Re: Cylinder numbering for UMZ 417

The voltage sensor consists of a rotor and a stator. The second terminal of the winding is electrically connected to the housing in the assembled sensor-distributor. 6. Install the distributor sensor cover, check the correct installation of the ignition wires to the spark plugs in accordance with the operating order of the engine cylinders 1–2–4–3, counting counterclockwise. After each ignition installation, check the accuracy of the ignition timing by listening to the engine while the vehicle is moving.

Numbering from the radiator. Remove the spark plug from the first one, tighten it to compression (check with your finger to see how it hisses), turn it until the moment of ignition (according to the marks on the pulley), and look at the slider. Insert the first wire where the slider is, and the rest are in order according to the direction of the slider.

I apologize for the lame question, but the previous owner of the automobile claims that the numbering of the cylinders in the UMZ 417 does not come from the radiator, but from the passenger compartment. I have encountered this in the French.

And both valves of the first cylinder are closed? Timing gears by marks?

Set the TDC in cylinder 1, remove the distributor from the drive (a boot in common parlance) and look inside. Sometimes the distributor drive is installed incorrectly. Try setting the ignition very early, if it gets better, move the distributor drive gear by 1 tooth. Just carefully reinstall the oil pump drive.

Driving without interference: set the ignition on the UAZ

The operation of a car engine is impossible without correctly set ignition timing. Remove the cover from the ignition distributor. For example, for a VAZ-2106 car, the switch can be installed in the free space between the washer reservoir and the left headlight. Drill 2 holes and screw the switch with self-tapping screws. Correctly setting the ignition timing in a contactless ignition system makes it possible to operate the car in comfortable conditions. Set the crankshaft to a position that corresponds to the ignition timing of 5 degrees. Check the order of connecting the high-voltage wires of the engine cylinders.

The ignition system is fundamental to the normal operation of a car engine. If any actions were incorrect, this will be reflected when the engine is started by the starter and the car is moving. All you need to do is adjust the spark supply - set the ignition correctly on the contactless system. Tighten the bolt at the pointer on the sensor-distributor housing. Be sure to check how the ignition wires are installed to the spark plugs, taking into account the order of operation of the cylinders 1-2-4-3. If there is no detonation, we increase the ignition timing.

Serves to turn on and off the current in the primary circuit of the ignition system and to turn on the starter.

The UAZ distributor is considered one of the important components of the ignition system in a vehicle. What is the connection diagram for electronic or contactless ignition on a UAZ 417, how to convert contact ignition to contactless? Why does the coil heat up and how to adjust and adjust the advance angle? The ignition system can also be electronic. First of all, you must lock your car in one place by pulling the parking brake lever.

The ignition must be installed if the ignition distributor is removed from the engine or if the ignition timing is incorrect. TDC according to the mark on the engine crankshaft pulley (Figure 15.13). The following characteristic malfunctions are possible in the ignition system: the ignition system does not work, the ignition system works intermittently, the ignition timing is incorrect.

This will be the beginning of the compression stroke in the 1st cylinder. 5. Tighten the locking screw and check the gap between the contacts again. 6. Install the rotor and secure the distributor cap.

With the help of an emergency vibrator, the contactless battery ignition system of the UAZ can operate in the event of a failure or breakdown of the transistor switch or stator coil of the sensor-distributor. To switch to working with an emergency vibrator, you must disconnect the wire from the short-circuit terminal of the switch and connect it to the output of the emergency vibrator.

This is visible not only when starting the engine with the starter, but also when the car itself is moving. Afterwards, you need to check the installation of the ignition wires according to the basic order of operation of the cylinders one-two-four-three, counting counter (hours). After you have installed the ignition, you need to check that it is installed correctly while driving.

Operating principle of the ignition system

Ensuring that the fuel-air mixture ignites at the correct time for efficient operation of an internal combustion engine is the primary task of ignition. This occurs in strict accordance with the predetermined operating sequence of the engine cylinders. The ignition coil 16 is connected in series with an additional resistor 14 in an electrical circuit. It closes automatically when the engine is started by the starter.

This leads to a significant increase in the breakdown current of the primary circuit. Ignition coil 16 generates high-frequency pulses in the vehicle's on-board electrical system. Flashes of high voltage interrupt the spark on the spark plugs 12, screwed into the top of each cylinder, where the working fuel mixture is compressed.

The coil consists of a primary winding and a secondary winding. The primary winding is wound onto the secondary. This is how the UAZ 469 ignition system works. Inside the coil there is a core and a ring magnetic circuit. Both of these components are made of special electrical steel. The reel is closed with a carbonite cover in a housing with a rubber seal.

Transformer oil is poured into the cover for cooling. This material significantly increases the winding insulation and effectively removes heat from the coil body. To avoid damage to the coil and overheating, it is not recommended to leave the ignition on when the engine is off.

Distributor 8 distributes high-voltage pulses to all cylinders of the internal combustion engine strictly sequentially. The distributor or breaker-distributor is installed in a standard location on the left side of the engine cylinder block. This mechanism is driven by the oil pump shaft. From the cover side, the shaft rotates counterclockwise.

What kind of ignition system is there for UAZ 469?

Contact ignition on the UAZ 469, which is now considered obsolete. However, domestic manufacturers still use it. The system delivers a pulse of a certain power. This pulse appears in the ignition distributor. The contact ignition circuit of the UAZ 469 is simple and straightforward. This is its advantage. The driver can fix any malfunction and make adjustments with his own hands. Prices for components are low.

Transistor or contactless ignition system in the UAZ 469. The contactless ignition system is installed on many types of cars. It has a number of advantages compared to the contact design. The spark created by such a device is much stronger. This occurs due to an increased level of electrical voltage in the secondary winding of the ignition coil. The transistor ignition system is equipped with an electromagnetic mechanism. It ensures stable, continuous operation of the entire system, smoothly transferring energy to components, parts and mechanisms. Correctly adjusted ignition with a working internal combustion engine guarantees high power and significant fuel savings. Long-lasting and reliable operation is ensured by following the drum motor's maintenance intervals. It should be lubricated and adjusted every 10,000 km. The disadvantage of a contactless ignition system is the difficulty of repair. It cannot be repaired yourself, since this requires specialized diagnostic equipment, available only at service centers and stations.

Electronic ignition system of the UAZ 469. This type of ignition is the most technologically advanced, but at the same time it is not cheap. Modern car models are equipped with such devices. It has advanced technology that provides not only high torque, but also a number of other engine parameters. Advantages: easy adjustment of the advance angle, no need to check contacts for oxidation. In engines equipped with electronic power take-off, the fuel mixture burns up to 100%. Repairs may only be carried out at a service station.

Underwater ignition on the UAZ 469 This is a sealed ignition system that is not afraid of being flooded with water, falling into deep holes, or driving in the open air during snow and rain. With normal ignition - contact or non-contact - 50% of the spark power is lost inside the barrel, between the cap and the guide. Let's find out why this happens.

There is a small space between the electrical contacts, which are the distributor cap and the guide. The flow of electricity in this space absorbs most of the additional current. In the case of contact ignition, an additional part of the energy is spent for this purpose due to the operation of the cam.

The underwater ignition is designed in such a way that the spark from the coil goes directly to the spark plug. During this process, it does not lose its main power, except for the resistance of the high-voltage wires. The power losses here are very small, so they can be neglected.

It is worth noting that in most foreign-made cars, a coil is installed separately for each cylinder, which is located directly on the spark plug, and the losses, accordingly, are quite insignificant.

We install and configure the ignition, change the distributor drive on UAZ vehicles

The UAZ distributor is considered one of the important components of the ignition system in a vehicle. Correct adjustment of this mechanism ensures optimal operation of the power unit as a whole. You can learn more about the principle of operation of the ignition system and how to set it up correctly with your own hands from this material.

Review of SZ on famous UAZs

UAZ ignition order - how to set, order of spark plugs

The UAZ distributor is an important part in the ignition system of this vehicle. Its optimal adjustment guarantees efficient operation of the unit as a whole, increases its performance and efficiency, and allows the engine to be operated in any conditions and situations.

Setting up the ignition system so that it works correctly is not as difficult as it seems at first. But first of all, it’s worth understanding exactly how UAZ systems are structured as a whole and understanding their circuits. And if you do everything according to the recommendations, in the right order, then adjusting everything will not be difficult.

Review of SZ on famous UAZs

What is the connection diagram for electronic or contactless ignition on a UAZ 417, how to convert contact ignition to contactless? Why does the coil heat up and how to adjust and adjust the advance angle? First, let’s look at the main points regarding the action and types of SZ.

Operating principle of SZ

Contact system diagram

The ignition system, or rather its correct setting, plays a big role in the operation and starting of a car engine. With correct adjustment, the combustible mixture will burn correctly in the power unit as a result of the supply of charge through the spark plugs. A spark plug is placed on each cylinder of the UAZ engine, each of which is turned on in a certain order, in turn, delivering a discharge to the cylinder after a certain time. It must be taken into account that any SZ makes it possible not only to deliver the required discharge, but also determines its strength.

Due to its technical characteristics, the car’s battery cannot produce the voltage and current required to ignite the mixture. This is due to the fact that the battery can only produce a current of a certain strength. And thanks to the correct operation of the system, the current value increases significantly, which allows you to successfully ignite the air-fuel mixture.

The operating principle of the system consists of several stages:

First, the driver inserts the key into the ignition and turns it, electrical energy is stored in a coil.
Then the coil converts the low-voltage voltage in the on-board network of 12 volts into high-voltage. As a result, the voltage value increases to 30 thousand V.
After this, the discharge is distributed and supplied to one or another spark plug.
The candle itself produces a spark that ignites the mixture.

Diagram of the UAZ contactless system

What types of SZ are there?

Domestic UAZ vehicles can use one of three ignition systems; let’s look at each of them in detail:

Contact view. This type of SZ is outdated, however, it is used on most machines. In such a system, the principle of operation is to issue a certain impulse that is formed in a distributor - a distribution device. The contact system is considered one of the simplest in terms of design, which is an advantage, since if a malfunction occurs, the car owner will be able to independently check and repair the system. In addition, prices for structural parts of the contact system are usually affordable, which is good news. The contact SZ includes a coil, a switchgear, a breaker, a capacitor and spark plugs.
Non-contact type, also called transistor type. Compared to the contact system, the contactless system has more advantages. The resulting spark has a higher power, which is achieved due to the formation of high voltage in the secondary winding of the coil. Also, contactless systems are equipped with an electromagnetic device, which makes it possible to achieve more stable operation of the engine. Ultimately, if the UAZ power unit is configured correctly, then by using a contactless system you can not only increase its power, but also achieve fuel savings, albeit insignificant. Also, such systems are easier to maintain. One of the main nuances in terms of maintenance is the need to periodically lubricate the distributor drive - at least every 10 thousand kilometers. One of the main disadvantages is the difficulty of repair. In practice, repairing a contactless SZ will be problematic, since diagnosing the system will require equipment that is usually available at a service station.
The ignition system can also be electronic. This option is currently considered one of the most progressive and expensive; it is installed mainly on new cars. Compared with contact and non-contact systems, the electronic system has a more complex structure. The main advantage of this system is that, if necessary, the process of adjusting the ignition angle will be much easier. In addition, there are no contacts in the electronic system that are susceptible to oxidation. It should also be noted that in practice, the combustible mixture in the cylinders of a power unit with an electronic system almost always burns completely. But despite all the advantages, electronic repair systems also have their disadvantages, which relate to device repair. It is almost impossible to repair such an SZ with your own hands, since to perform this task, again, you will need equipment (video published by Nail Poroshin).

Expert recommendations on how to configure correctly

So, how to set the advance angle yourself in order to achieve proper operation of the UAZ engine:

First of all, you must lock your car in one place by pulling the parking brake lever. Rotate the crankshaft so that the piston of cylinder 1 reaches TDC (top point). In this case, you need to ensure that the hole on the crankshaft pulley coincides with the mark marked on the timing gear cover.
After this, remove the cover from the distribution mechanism. After dismantling, you will be able to see the slider, which is located inside the cover itself, opposite the contact. If there is no slider, you should turn the crankshaft 180 degrees again, and then set the octane corrector to 0. Using a wrench, you will need to screw the pointer to the distribution mechanism housing so that it aligns with the middle mark. When these steps are completed, the fastening bolt with which the plates are attached to the distributor body must be loosened slightly.
Then, holding the slider in one place with a finger to prevent it from rotating, you need to carefully rotate the housing itself, this will allow you to remove possible backlash in the drive. The housing must be rotated until you achieve alignment of the sharp end of the stator mechanism petal with the red mark located on the rotor device. After this, the plate itself must be secured to the body using the appropriate bolt.
Once you have completed these steps, you need to replace the controller cover and check the high voltage cables. You need to make sure that these wires are installed in the correct sequence, taking into account the firing order of the cylinders. When you manage to correctly adjust the lead angle, you need to make sure that the entire procedure was performed correctly.
To diagnose the correctness of the actions performed, you need to start the engine of your UAZ and wait about 5-10 minutes until the power unit warms up. The operating temperature of the engine is about 90 degrees; you can wait until the internal combustion engine warms up to 80 degrees. Then you need to drive onto a flat road and accelerate the car to 40 km/h, after which you should sharply press the gas. At this moment, the car will accelerate and if, when the speed increases to 60 km/h, a short-term detonation (metallic knock) is heard from under the hood, then this indicates that all actions were performed correctly. If the detonation is too long, the system will need to be adjusted. To do this, the housing of the distribution mechanism will need to be turned one notch or half, and it must be turned counterclockwise. If the diagnostics showed that there is no knocking of the “fingers” at all, then the advance angle should be increased. To do this, the mechanism should be turned in the opposite direction.

Why turn on the ignition?

Connection diagram for ignition system components

In order to properly configure and adjust the engine cylinders on a UAZ-469 vehicle, you must have certain skills. We will talk about them later, but first we invite you to find out for what purposes it is necessary to correctly adjust contactless ignition and what this may entail. After connecting the key to the ignition switch, numerous components and mechanisms are activated, without which the operation of the engine is impossible.

So why set this parameter:

The engine will operate optimally and stably in all modes. Otherwise, its operation will be unstable and cause inconvenience to drivers.
Cold engine starting will be significantly improved. Of course, if you want trouble-free starting of the engine in thirty-degree frost, you must also fill the engine with the correct oil and check the suitability of the spark plugs.
Fuel consumption is normalized, otherwise it may be increased.
The drive power will be optimal, as indicated in the service book (the author of the video is the Smotri Vidik channel).

How to set the ignition correctly

To install the ignition in a UAZ 469 car, you must follow the following recommendations:

Remove the drum cover with the rotor. Check the gap between the contacts. It can be adjusted. There should be a gap of 0.35 - 0.45 mm between the contacts at maximum expansion. It is best to make adjustments using a set of measuring sensors. Too small a gap produces a weak spark. If the gap is too large, there may be no spark at all. If the clearance is normal, the rotor can be installed in its normal position.
Using a spark plug wrench, remove the spark plug of the first cylinder. Cover the spark plug hole with your finger. Use the crank to turn the crankshaft until compressed air pushes the pin out. This moment is called the beginning of the compression stroke of the first cylinder.
Continue turning the crank until the hole on the pulley and the pin on the camshaft cover line up. The rotor should be located against the internal contact on the cover, connected to the high voltage wire from the spark plug of the first cylinder.
Rotate the octane corrector plate together with the drum so that the mark coincides with the center mark on the scale of the plate.
Turn the distributor body slightly counterclockwise. Turn until the drum contacts close.
Connect the indicator light to the connector. Connect one terminal to the low voltage terminal of the tram circuit breaker and the other terminal to the machine ground. The indicator light can be connected to the car body.
Turn on the ignition and carefully turn the drum clockwise. Turn until the indicator lights up, then stop turning. It may happen that the light bulb does not light up. Repeat all steps from the beginning.
Tighten the distributor mounting screw. Place the cover in place, focusing on the center line. Check the adjustment starting with the first cylinder. The check is performed counterclockwise.

A guide to replacing a distributor with an oil pump drive

Before installing a new distributor with a drive, you need to weigh your strengths, since it is not recommended to make mistakes when performing work.

So, how to replace and install the distributor:

Turn off the ignition and remove the distributor cover; the tips and high-voltage cables are connected to it.
Then you need to disconnect the wire connected to the switch from the distribution mechanism. You also need to disconnect the pipe connected to the vacuum regulator.
Taking a 13mm wrench, unscrew the two nuts securing the device and remove the mechanism along with the oil pump drive from the power unit.
After completing these steps, you will be able to see the gasket located under the drive. If as a result of these actions the position of the crankshaft has not changed, then simply install a new mechanism, making sure that the slider is located opposite the mark. All actions are performed in reverse order. When the installation is completed, the advance angle is adjusted.
If, as a result, the location of the shaft has changed, then before installation it is necessary to move the piston of cylinder 1 to top dead center. You need to ensure that the marks on the pulley align with the pointer on the motor itself.

How to check the ignition coil

Checking is necessary in the following cases:

The mechanism does not stall when the ignition is turned off.
A short circuit has occurred.
The spark plugs in the ignition system have failed.
The coil heats up, causing the system to overload.

In order to check the ignition coil, you need to turn off the power unit and open the hood. Then you need to find the coil. To do this, it is recommended to follow the wires that lead from the distribution mechanism in the opposite direction. After this, you need to disconnect 1 high-voltage wire from the spark plug. Before the procedure, you must wait until the engine has completely cooled down. This may take 15-25 minutes.

Then you should dismantle the spark plug using a special nozzle. This must be done carefully and make sure that debris does not get into the hole, because. this will lead to malfunction of the power unit. You need to connect the wire back to the spark plug. To perform this operation, it is recommended to use pliers with insulated handles.

After this, you need to touch the threaded side of the candle to the bare metal. When the ignition is turned on, all elements of the vehicle’s electrical equipment will begin to work, which means that the coil is functioning properly. The driver performing repair work should see a blue spark. If it is not there, then the system is faulty. If an orange spark occurs, it means that insufficient voltage is being supplied. This may be due to poor contact, low current, or defects in the coil body.

Another way to check the ignition coil connection:

Remove the coil from the car. To do this, you need to disconnect the wires of the distribution equipment, remove the fasteners from the coil body using a wrench.
Determine the condition of the mechanism using an ohmmeter. You need to touch the probes to the primary winding, touching 2 contacts at the same time. After this, it is necessary to measure the condition of the secondary winding and compare the obtained indicators with the factory ones, which are in the repair manual.

Before starting work, it is necessary to place the transport on a flat surface and secure it with special locking devices. When checking the device, it is recommended to wear protective clothing (mask and goggles, as well as gloves).

We carry out the wiring diagram for electronic ignition on a UAZ

Classics of the domestic auto industry

Many UAZ vehicles are equipped with a contactless ignition system. It makes it possible to save fuel, reduces the amount of harmful substances in gases, and makes it much easier to start the car in winter.

The connection diagram for electronic ignition on a UAZ is not as complicated as it might seem at first glance. A person who has at least a little knowledge of technology will be able to repair and correct problems himself, if any arise.

Ignition system on UAZ 469

The ignition system for the UAZ 469 can be made not only at a service station, but also with your own hands. It consists of:

ignition coils or distributor;
switch;
emergency vibrator;
variator (additional resistor);
spark plugs.

Today, contactless ignition systems are most often preferred. The most interesting thing about them is the switch.

If the crankshaft rotates at a frequency of 500 revolutions per minute, it turns out that the signal at the sensor output will change too quickly. This mode is used if you start the engine with the starter. At this time, there will be not just one spark on the candles, but many, which will make it possible to start the car easily and quickly. Ignitions on UAZ have a simple design.

Contactless ignition is more convenient to use than contact ignition.

Installation instructions

Installing contactless ignition on the UAZ 469 is quite easy. It is easy to configure and install, and the reliability of the UAZ ignition can only please us. It works very accurately, even in the cold season, when starting the car is quite difficult.

Once a new system has been purchased, it must be installed. To install you will need:

drill;
self-tapping screws;
drill;
key to 38;
open-end wrench 13;
Socket and socket wrenches for 10 and 8.

Ignition on the UAZ 469 is done as follows:

First, the engine must be set to the TDC mark using a 38 key. Before you do anything with the equipment, you need to remember the location of the parts before replacement.
We look at how the slider and distributor are installed, so that we can then install a new one in the same position. Next, we find the place where the ignition coil is located, on which we find the B + mark and look at the location of the wires and what is attached to what. After everyone has looked, you can unscrew the coil. We remove the distribution lock, place the switch, and also install the ignition coil and attach it to the body. We connect standard wires. From the switch, wires labeled + are attached to terminal B, and a second wire is attached to terminal K.
You connect the distributor, but the nut is not tightened completely. You need to connect the wires from the switch to it. After this, you need to check the location of the slider and distributor, put on the cover and connect all the wires in the order in which they were before replacement.
When everything has already been replaced and secured, you should start the engine, check how it works, and adjust any inaccuracies.

Adjusting the ignition of a UAZ is a fairly simple task. With the engine running, you need to turn the distributor very slowly to find the position at which the engine will run smoothly and the speed will be high.

The UAZ 469 car has an ignition coil, which is also a kind of transformer that converts low voltage to high voltage. When the engine is running, current flows through an additional resistor into the primary winding of the ignition coil. It is located between the legs of the fastening brackets - in the insulator.

When the engine is started using the starter, the resistor is turned off, and the current flows into the primary winding without entering it, which makes starting the engine much easier due to the enhanced spark.

How to connect the ignition switch

Replacing the ignition switch involves dismantling the old one and installing a new mechanism with its subsequent connection. To remove the old lock you will need a Phillips and flathead screwdriver.

The procedure for dismantling the old vehicle ignition system lock:

Remove the fasteners from the lower trim panel of the steering column.
Insert the key into the lock and set it to the zero position, at which the steering mechanism will be locked.
Remove the steering column.
Unscrew the ignition switch mounting bolts.
Insert a flat-head screwdriver into the small technological hole and press the latch that holds the lock.
Push the lock out of its seat.
Disconnect all system wires.
Install a new lock, connect the wires and reassemble the mechanism, performing all the steps in reverse order.

All wires are connected in a clockwise direction.

To terminal number 50 you need to connect a red wire, which is responsible for the stable operation of the starter device.

To terminal number 15 you must connect a blue wire with a black stripe, which is responsible for heating the vehicle interior.

A pink wire is connected to pin number 30, and a brown wire is connected to 30/1.

The black wire must be connected to the INT connector, which is responsible for the operation of the side lights and headlights.

After all the wires are connected, you need to connect the battery terminal. A black wire should be connected to the top of the terminal. Then you need to start the engine and check the serviceability and functionality of the entire ignition system. First, it is recommended to check the operation of electrical devices, and then the serviceability of the starter mechanism.

If all wires are connected correctly, then when the ignition system key is in the zero position, all elements of electrical equipment will be disconnected from power. When the key is turned to the first position, the system is activated, which controls the internal combustion engine, generator set, headlights and brake lights, as well as washers and windshield wipers. When the key is moved to the second position, the starter is activated, the anti-theft system rod extends and retracts when the key position is changed.

If this does not happen, it means the wires are connected incorrectly. It is necessary to disassemble the mechanism and repeat the connection procedure.

UAZ 31514 wiring diagram for ignition conversion

Many UAZ owners know about the vagaries of classic ignition, which sometimes presents unpleasant moments. And often craftsmen find ways to modernize a problematic unit or an entire system. And one such method of improving the launch system with your own hands will be discussed in this publication.

In the photo, UAZ 31514 is a reliable all-terrain vehicle for many purposes.

General concept

The contact ignition circuit itself is not bad, because humanity has been using it since the advent of the first car. But, of course, it is far from the capabilities of contactless ignition. Therefore, many UAZ owners, in an effort to improve the performance of the power unit, reconfigure it.

General ignition circuit for older UAZ models

And not only UAZs, but also other domestic cars, for example, the wiring of the Moskvich 2141 and a number of other brands and models are subject to alterations.

Effect of modernization

What is important is that the engine compartment and interior electrical wiring of the UAZ 31514 remains virtually unchanged, and the alteration itself is characterized by the installation of new elements under the hood.

As a result:

The engine begins to operate stably in all modes;
Improves cold starting;
Fuel consumption is normalized;
The engine power will reach the passport data.

Differences between ignition systems

The main difference between the two systems is the moment of sparking:

In classic ignition, a slider under the distributor cover is responsible for this when it comes into contact with the output contact on the spark plug wire. In this case, the supply of a high-voltage pulse occurs with an increase. It seems to be lubricated, reducing the spark power at the spark plug electrodes.
In contactless ignition, the switch generates a charge and releases it almost instantly upon receiving a signal from the Hall sensor. As a result, the candle produces a more powerful spark. Among domestic off-road vehicles, the Niva has a similar contactless ignition system - see the VAZ 21213 wiring diagram.

The electronic switch is often mounted in UAZ vehicles on the partition on the left side.
Please note! More powerful sparking promotes self-cleaning of the spark plug, because The fuel burns intensively, leaving no deposits.

What to buy

In fact, you don’t need to buy much, and if you have a working distributor and reel, then the list of purchases will be minimal.

So, you need to buy:

Hall Sensor;
High-voltage wires (preferably silicone);
Switch from VAZ 08.

Advice: If your UAZ is already many years old, then we recommend that in addition to the already indicated list, you buy a new distributor, a coil, and you will also need UAZ 31514 wiring with connectors for the switch.

For reconfiguration and operation, you will also need a new UAZ 31514 wiring diagram, which is shown in the photo below, and which you can print for convenience.

For a new ignition - a new circuit

You can also make your ignition system more powerful by upgrading it with two kits at once:

Two switches;
Two Hall sensors;
Two ignition coils.

With this approach, each subsystem will be responsible for sparking 2 cylinders at once:

First and third;
Second and fourth.

Most often, UAZ cars that take part in competitions or are used by professional fishermen and hunters are subjected to such serious modifications. The video below shows how an engine works with such a system.

Advice: if you use your UAZ 31514 in everyday life, not related to extreme sports, then it is enough to limit yourself to alterations with one set - it’s easier to maintain it. After all, domestic all-terrain vehicles use a proven UAZ wiring diagram.

Material

Polyvinyl chloride or polyvinyl chloride is often used as insulation for high-voltage wires. These are the cheapest materials. Higher quality ones have elastomer insulation with a temperature range from -30 to +1800 °C.

The best insulation for high-voltage wires is silicone. Excellent parameters and a high range of operating temperatures, from -50 to +2500°C, long service life, these are the best recommendations for choosing it.

The weak point of some modern GDPs is the conductor. If you pull the wire, it may break or jump out of the clamp. It can also burn out during operation. On injection engines this is not always noticeable and its resistance must be checked periodically.

Look at the structure of the high-voltage wire.

Materials and arrangement of high-voltage wires

Rework

Actually, the work itself comes down to remaking the distributor, which will no longer have a high-voltage part - an electronic switch will generate high-voltage pulses for it . The photos below show the location of two sensors at once.

The sensors are attached to the base and the contact plate has curved edges

Pay attention to the shape of the contact plate:

It has curved ends - the sensors are located vertically;
Flat – the sensors are mounted horizontally.

Flat plate option
Flat plate option

Both options are working, it all depends on the design of the distributor. In the future, you only have to adjust the ignition. The instructions are simple - you must remember that sparking begins when the edge of the plate is in the center of the Hall sensor.

The order is as follows:

Rotate the crankshaft until the piston in the first cylinder reaches TDC;
Rotate the distributor body until the contact plate is in the sensor slot;
Carefully tighten all mounting screws to eliminate any play.
Start the engine.

How to set the ignition

In order to correctly adjust the UAZ ignition the first time, you should adhere to the following recommendations:

First you need to remove the cover that belongs to the distributor with the rotor. After this, the size of the gap between the contacts is checked and checked against established standards. Its maximum size can be from 0.35 to 0.45 mm, no more and no less. This plays an important role here and directly affects the operation of the engine. If the gap is too small, it will produce a small spark and because of this, the unit may operate intermittently. And if it is too high, the spark will not occur at all. If the gap deviates from the previously stated standard, it can be adjusted. Adjustment is best done using a set of feeler gauges. Having made a normal gap and checking it again, the rotor can be returned back and proceed to the next steps.
Next, you need to carefully unscrew the spark plug of the first cylinder with a specially designed wrench. The resulting hole must be closed with your finger and held, while turning the crankshaft with the starting handle. When the compressed air begins to push the pin out of the hole, which means the start of the stroke, you need to continue turning the handle until the holes on the pulley and pin coincide. The rotor should be located opposite the internal contact of the cover, connected to the high-voltage wire from the spark plug of the first cylinder.
Then you need to turn the octane corrector plate with the distributor. It is necessary to ensure that the mark coincides with the middle mark on the scale of the plate. Then, having completed this operation, you should slightly turn the distribution mechanism housing counterclockwise. Do this until the contacts of the distributor connect to each other.
Next you need to connect the control light. The first contact must be connected to the low voltage terminal, and the second to the machine ground. It is possible to connect the lamp to the vehicle body.
Next, you need to activate the ignition and start turning the distributor to the left until the lamp lights up. After this you need to stop. If tanning does not occur, then you should repeat everything all over again and wait for a positive result. You can't move on without it.
Then, when everything works out, you need to tighten its mounting bolt on the distributor. When the cover is in place, you need to check how everything is adjusted. This must be done starting from the very first cylinder, to the right. At this point the work can be considered complete, and if everything is done correctly, the motor will function correctly and without interruption.
