Information on seat belts:

for consumers of the Republic of Belarus: according to the Resolution of the State Committee for Standardization of the Republic of Belarus dated July 14, 2011 No. 46 “On introducing amendments and additions to the Resolution of the State Committee for Standardization of the Republic of Belarus dated December 16, 2008 No. 60”, it is mandatory to equip cars of categories with seat belts N2, N3, issued for circulation on the territory of the Republic of Belarus, introduced on January 1, 2012.

for consumers of the Russian Federation: according to “Changes No. 1” to the “Rules for carrying out work in the certification system of motor vehicles and trailers dated April 1, 1998 No. 19”, approved by Order of the Federal Agency for Technical Regulation and Metrology No. 3453 dated December 10, 2007, mandatory installation of seat belts on cars of categories N2, N3, put into circulation on the territory of the Russian Federation, was introduced from the date of entry into force of the specified “Changes No. 1”.

Cars manufactured before the entry into force of these regulations were equipped with seat belts at the request of the consumer.

Retrofitting cars with seat belts can be done at service stations. When equipping cars with seats manufactured by MAZ OJSC on a torsion bar suspension (mechanical), the driver and passenger workplace must be converted to seats manufactured by MAZ OJSC with air suspension. At the customer's request, the passenger seat can be equipped without suspension.

Before repairing the electrical equipment of a truck, it is extremely important to study the MAZ wiring diagram. As a rule, it describes the power supply system for all devices in vehicles that require power.

Making changes to the power distribution can cause serious damage.

Below we will note all the components that make up the MAZ Zubrenok 4370 wiring diagram.

We remind you that if you need to buy spare parts for MAZ electrical equipment, you can use our catalog.

Purpose of the MAZ block

Thanks to the modern BSK 4 MAZ (multilayer printed circuit board), the electrical equipment circuits of Belarusian trucks are protected from overvoltage.

The manufacturer of the part is JSC MPOVT.

The high quality of the block meets international standards.

Thanks to well-established production and the use of the latest technologies, the BSK 4 MAZ unit has the following characteristics:

• Voltage - 24 ±6 V;
• The operating mode of the part is nominal S 1;
• Complies with GOST 3940;
• Temperature range – from -55 to +60 degrees Celsius;
• There is a function of increased protection against the ingress of liquid, dust and other foreign bodies;
• Weight – 6.8 kg.

About the BSK-4 block diagram

On many forums, owners of dump trucks and MAZ trucks often ask to see a photo of the BSK 4 diagram.

However, this diagram is not included in vehicle operating manuals.

Usually it is necessary to repair the unit.

The process of troubleshooting and resoldering parts is extremely complex.

The fact is that even a professional is difficult to replace all the components with a guarantee of further work.

Therefore, if your BSK-4 unit is broken, we advise you to buy a new one. Repairing a spare part is extremely dangerous.

Fight for a lorry

Gas 51A was good for everyone and suited everyone. Its huge gas mileage and pre-war design with a lower-valve Dodge engine did not in the least bother the automotive companies where he worked, much less the manufacturers and management. The most inventive drivers installed carburetors from Gas-12 (Zim) on a low-power 70-horsepower engine, as a result of which the consumption increased even more and reached a cosmic 40 liters per hundred, but the power increased significantly. Some sources talk about an increase of 20 forces, but this is hard to believe.

Sooner or later, the 51st still required replacement, and the factory understood this very well. NAMI also understood, so they were actively looking for constructive solutions for building a car with similar characteristics. Let's say right away that all the titanic efforts of the most talented designers went to waste. Many years of work to create a practical truck for the national economy was shattered into pieces by a bureaucratic barrier that neither US nor the designers of the plant itself could overcome. In contrast to the excellent developments, which are worth a separate story, the country's farms have been receiving the same Gas 51 with minor changes for 50 years. Gas 5312 is a typical example of this.

A few words about the replacement

However, we will tell you an approximate algorithm for replacing a part using the BSK 4 scheme.

Typically, part failure occurs as follows:

• Pieces of multilayer boards and tracks burn out;
• There is a short circuit in the conductive harnesses or wiring;
• Block BSK 4 fails.

If you want to try to restore the part, do the following.

• Having previously studied the diagram of the BSK 4 MAZ block, remove the part. Then look closely at the damage.

If you find burnt tracks, carefully trim their channels so that they do not touch each other/

• If there is a small hole, seal it, for example, with epoxy.

Start soldering the elements from the back cover.

• With proper repair, all elements should come together.

We would like to emphasize once again that saving on BSK-4 is stupid, because by repairing it, you cannot guarantee the proper operation of the element.

If one of the new jumpers becomes disconnected, a short circuit will occur and therefore a fire.

All this can lead not only to the purchase of a new BSK-4 MAZ unit, but also to the replacement of more expensive parts.

You can make many mistakes during the renovation process.

For example, even after thoroughly studying the BSK 4 MAZ diagram, most repairmen forget to remove the cuttings of the tracks.

In the future, leakage will occur through the board material. And there may be smoke coming from under the car.

Work on studying the diagram of the BSK-4 block, then subsequent repairs will require about 5,000 - 8,000 rubles.

In fact, half the cost of a new unit.

Therefore, we recommend that you buy only a new BSK 4 for MAZ. This is the only way you can be sure that over time a short circuit will not occur in the truck’s electrical equipment.

To avoid failure of the BSK 4, we recommend monitoring the compliance of the fuse ratings and the condition of the electrical equipment of the vehicles.

Maz 5440 and Maz 6430 are the general designations for two series of truck tractors of the Minsk Automobile Plant produced from 1997 to the present with various modifications and changes (643008, 6430A8, 643005, 6430A5, 6430A4, 631208, 6312A8, 544009, 5440A9 , 544008, 5440A8, 544005, etc.) and generations (Euro 3 4 5 6). In this article you will find a description of the most popular fuse and relay blocks Maz 5440 and Maz 6430 with diagrams and their locations.

Disassembling the generator

We disassemble the device as follows:

Unscrew the pulley mounting nut and remove the pulley

You should pay attention to the key - it is better to immediately remove it and put it in a safe place so as not to lose it; Unscrew the two screws securing the brush assembly and dismantle the assembly; Unscrew the three screws of the rear plug; We unscrew the long tightening screws on the rear cover of the generator; they tighten both parts of the housing together. Remove the back cover and disconnect the wires on the cover near the diode bridge.

The fourth generation of the GAZ 3307 medium-tonnage truck was born in 1993 and completely replaced its predecessor, the GAZ 52/53, on the assembly line. As has been customary all these years, the car was largely unified with its platform, but it also had some differences that made it more modern.

Power supply and electric starting system

The vehicle's power supply system consists of two sources: batteries and an alternating current generator set. In addition, the system includes a number of intermediate relays, a battery mass switch and a key switch for instruments and starter.

The electric starting system includes batteries, a starter, a battery disconnect switch, a key switch for instruments and the starter, an electric torch device (EFD), a vapor-liquid heater (SHL), and intermediate relays.

Rechargeable batteries

MAZ vehicles are equipped with batteries of the 6ST-182EM or 6ST-132EM type. The nominal voltage of each battery is 12 V. In a vehicle, two batteries are connected in series, which increases the operating voltage to 24 V.

Generator set

The generating set GU G273A is an alternating current generator with a built-in rectifier unit and an integrated voltage regulator (IVR)

After 50 thousand km of vehicle mileage and subsequently at each maintenance-2, it is necessary to remove the control unit from the engine, disassemble it, and check the condition of the ball bearings and electric brushes. Damaged bearings and heavily worn brushes should be replaced.

Starter

On MAZ vehicles, a starter type ST-103A-01 is installed.

Battery disconnect switch

The VK 860B type switch is designed to connect batteries to the vehicle ground and disconnect them.

Electric flare device (EFD)

The electric torch heating device does not require separate maintenance work. Failures that appear in the electronic control unit are eliminated by replacing the faulty element.

Pre-heater electrical equipment

During operation, the electric spark plug, thermal electric heater and fuel electric valve may fail. These devices are non-separable and can be replaced when they fail.

The transistor switch is made of electronic elements, hermetically sealed, does not require maintenance and is also not repairable.

The electric motor of the pump unit is not maintained during operation. Since the electric motor operates for a short time, it ensures normal operation of the heater when the vehicle runs for several major repairs.

Verification Recommendations

Many novice car enthusiasts are interested in learning how to remove the ignition coil, because the procedure must be carried out with the device removed. It is worth knowing about the main types of problems that arise during the operation of this module.

Basic faults

It is quite easy to find the device in old cars, because it was installed within the driver’s field of vision. If you start your search with the central conductor of the ignition distributor, then there will be no problems. You can also quickly find individual coils, most often located above the candles.

Among the main signs of malfunction of this module, the following should be noted:

• There is no spark and the engine cannot start.
• The power plant throttles during operation, and this is especially noticeable at high humidity.
• During computer diagnostics, misfires were detected in some cylinders.
• There are drops in traction when you press the accelerator pedal.
• The power plant struggles and primarily at low air temperatures.
• The device is experiencing serious overheating.
• The conductors suitable for the device have changed color.

Often, vehicle owners are partly to blame for problems with this element. Wanting to save money, many decide to use non-standard spare parts. If we talk about the most common malfunctions, we can note:

• Reversing the battery polarity.
• Frequent coil overheating.
• Electrical wiring shorted.
• Mechanical damage to the device.
• Sudden temperature fluctuations.

Carrying out diagnostics

It is also necessary to familiarize yourself with the information on how to test the ignition coil with a multimeter, because this information will be useful to all owners of mechanisms equipped with gasoline power plants. This measuring device allows you to monitor voltage and resistance. The switch of the measuring device must be set to the “200 Ohm” position and, applying probes to the “+” and “K” contacts, measure the resistance value of the first winding of the coil.

Most often, difficulties arise when diagnosing dual coils, since the primary winding in them is connected to the connector. To check it, you can use a multimeter only if the user is familiar with the coil circuit. Diagnostics of the secondary winding is carried out between two high-voltage conductors.

Without a certain set of knowledge in the field of radio electronics, it will be quite difficult to determine the malfunction of individual coils, since it is necessary to assemble an electrical circuit. However, there is one way that always works. If the power plant is tripping, then you should start sequentially disconnecting the coil terminals while the engine is running.

If after this the engine starts to double, then there is no spark in this cylinder. To solve this problem, you can carry out computer diagnostics. But even if during the test the cylinder number without a spark is indicated, this does not allow us to speak unambiguously about the coil’s malfunction. Knowing how to check the resistance of the ignition coil with a multimeter, you can quickly determine the source of the problem and replace the failed element. Many car enthusiasts replace branded coils on foreign cars with devices from VAZ, since they are much cheaper.

Overview of the MAZ 5440 electrical circuit design

A separate part is allocated to indicate light signaling and lighting equipment: flashlights, spotlights, headlights, fog lights, lighting in the cabin.

Power supply is required for instruments located on the driver's panel, as well as an audible alarm that informs about problems with pressure in the brake system.

A significant part of MAZ electrical equipment is the mounting block, which contains fuses.

The device includes a multilayer printed circuit board, and if there is a short circuit in the MAZ electrical wiring and current-conducting harnesses, the unit fails. Sometimes the unit can be repaired, but more often it needs to be replaced.

When removing and installing the unit, it is important to carefully monitor compliance with the connection rules.

Current-consuming devices should be connected in accordance with the Euro MAZ electrical diagram.

Do not forget that electrical diagram drawings do not reflect the actual location of elements.

The graphic representation shows the connection of the components with each other.

The nodes can be connected in series or in parallel, the components are located in the circuit in a certain order established by the manufacturer.

However, before repairing the system, we advise you to carefully study the MAZ diagram, because if the elements are connected incorrectly, a significant breakdown of the system may occur.

Features of GAZ 3307

This model was considered a transitional model, so the automaker did not consider it as an object for serious modification. The following was inherited from its predecessor:

1. Chassis;
2. Power unit;
3. Body, including its cargo modifications;
4. Basic controls.

New cabin

A new element of the GAZ 3307 car was a modern cabin. She was different:

In addition, thanks to the installation of a new cabin with increased functionality on the chassis, the electrical wiring of the GAZ 3307 was also modified. This was required by the appearance on the car:

1. Efficient ventilation and heating systems;
2. Power steering;
3. New instrument panel.

Electrical equipment

As for the electrical equipment, in connection with the manufacturer’s experiments trying to select the optimal power unit, the engine compartment wiring of the GAZ 3307 also underwent modernization.

1. Instead of the previously used DC generator, the car received an alternating current generator model G250-G2;
2. To protect the electrical equipment, a voltage regulator model 222.3702 was integrated.

The ignition system has also undergone a slight modernization:

1. Instead of the old B114-B ignition coil, a more powerful B116 was installed;
2. The old distributor R133-B was replaced with a modernized 24.3706;
3. An electronic ignition switch model TK102A appeared. Later, instead of it, the car was equipped with a universal switch 13.3734, as well as its modification - 13.3734-01;
4. The circuit uses a resistor SE107, and on a number of models the universal 14.3729 was installed (see also the Gazelle wiring diagram).

Lighting and light signaling systems

The lighting system includes headlights, spotlights, fog lights, front and rear lights, reversing lights, cabin and bed lights, an engine compartment light, lamps and a set of switching equipment (switches, switches, relays, etc.) .

The light signaling system includes turn indicators, brake signals, a road train identification sign and equipment for turning them on.

Starter repair

I decided to replace the brushes and bushings at once, and to do this, I repressed the copper-graphite bushings in the starter housing, and unwrapped them at a turner I knew. I sequentially rang the armature winding and the stator shunt winding - everything was normal.

After that, I installed the armature in the rear housing and assembled the bendix. Then, I installed the new brushes in place and closed the front starter cover.

Next, I disassembled the front cover of the solenoid relay, turned the contact washer over with the clean, unburnt side, and brought the contact bolts into one plane using a stone.

Then, I assembled the solenoid relay, installed it on the housing and checked the starter from the battery - turning on the Bendix worked easily and the starter turned at idle. I didn’t find any more faults and began to install the starter in place.

Mounting block MAZ - BSK-4

The electrical equipment system of modern MAZ-6430 vehicles uses a mounting block of fuses and relays (on-board system block) brand BSK-4 (TAIS.468322.003) produced by the Minsk plant OJSC “MPOVT”. The design of the mounting block uses a multilayer printed circuit board to attach electronic components, relays and fuses. In the event of short circuits in the vehicle's electrical wiring and current-carrying harnesses, the unit fails. An analogue of BSK-4 with the name BKA-4 can also be used.

Repair of the BSK-4 mounting block in case of defects in a multilayer printed circuit board is carried out by our specialists. If repair is not possible, replacement is required. To avoid failure of the BSK-4 mounting block, you must first monitor the compliance of the fuse ratings, as well as the condition of the electrical wiring of the truck.

Autoelectrics (electrics) and electronics of a MAZ vehicle have their own characteristics, disadvantages and advantages, and these features must be taken into account when operating a MAZ truck. A master specializing in the repair of MAZ auto electrics has extensive experience in repairing auto electrics (electrics) and knows the weak points in the electrics of MAZ cars. Skills and experience are very important in the work of a good truck electrician (electrician) on the road in order to minimize the financial losses of the customer due to downtime.

Broken shunt winding terminal

Again I dismantled the starter and disassembled it. The armature rang, but there were no breaks or short circuits in the windings to ground on the armature. The brushes had already rubbed into the commutator and the commutator itself was even and smooth.

After inspection, it became clear that the cause of the problem lies in the stator. It turned out that there was either a break in the winding or a short circuit of the winding to ground.

To be sure to ring the winding, it was necessary to disconnect it from the stator mass, and to do this, I unscrewed the 10-point bolt with which the second end of the winding was screwed.

Carefully bending the winding terminal away from ground, I tried to ring it. The winding was completely intact and the light of the probe lamp convincingly signaled this. There was also no electrical contact to the ground of the winding. Therefore, I had to screw the winding terminal into place.

I started to remove the terminal of the second winding and it turned out that it was loosely tightened. I completely unscrewed the bolt and removed the washer, and saw the tip of the terminal falling off the washer. I did not expect such a turn of events.

I tried to shake the winding and check the movements, but it sat rigidly on the pole. Then, I also rang this shunt winding, but found no breaks or short circuit to ground in the stator.

In a hurry, I wanted to simply solder the broken end of the terminal, but on reflection, I came to the conclusion that the reliability of such a solution would leave much to be desired.

I decided to simply install a washer with a larger outer diameter in order to press the remains of the terminal over a larger area. I found a suitable washer and, having stripped the end of the terminal, screwed it into place, using Grover's new washer.

The process did not take much time and installation of the starter in place also went quickly. Having finally tightened all the bolts and turned on the engine ignition, I started the engine. It started up at half speed and, barking as usual, blew smoke out of the chimney.

This repair turned out to be successful and I have not had to deal with a starter malfunction for a long time. And I have never had such a breakdown again.

However, thanks to this experience, I made it a rule to check the strength of the fastening of the shunt windings to the stator every time I repair the starter.

A modern starter for YaMZ 238 236 models is necessary to start the internal combustion engine. This function is performed by the primary rotation of the crankshaft at a certain frequency. In this article we will tell you about the main features of the device.

We remind you that in the YaMZ MAZ catalog you will find everything you need to quickly repair a truck.
