Before starting the engine using the ECU, turn on the instruments on the engine compartment panel with switch 9 Fig. The assessment of the starter condition may be incorrect if the voltage drop in all starting circuits exceeds the permissible value. The state of charge can be assessed by measuring the density of samples taken from the battery. With this voltage drop, the current shown by the ammeter should be recorded. Relay P1 is activated, contacts P1 through the turn signal switch connect the indicator lamps to the positive power supply terminal of the system. How to Read Car Wiring Diagrams

For measurements, you need an accurate voltmeter designed to measure low voltages. Based on the test results, the battery can be considered serviceable if the cell voltage is not lower than 1.5 V, i.e. It is turned on by the toggle switch on the left side.

Therefore, it is advisable to start checking by measuring the transition resistances in the places shown in Fig. The brake signal lights 6 are turned on by relay K4 of block 1. When you press the switch button 7, the indicator lamp of the light 9 should light up. When the measurement voltage is 24 V, the indicator lamp should light up, since transistor G4 is open to full excitation. Alarm. Device and principle of operation.

Specifications

When analyzing the main parameters of this model, it is advisable to mention that they can vary significantly and depend on the specific modification. It makes sense to study the most characteristic technical indicators, which are similar in most modifications of this model:

• the gross vehicle weight is 3225 kg;
• fuel tank volume 64 l;
• the design uses a single-plate clutch equipped with a hydraulic mechanism;
• Fuel consumption per 100 km averages 12.3 liters;
• tire size 175R16-185/175 R16 depending on the model;
• All modifications are equipped with a 5-speed manual transmission;
• The vehicle's carrying capacity is 965-970 kg.

This vehicle operates on a 4x2 wheelbase and is capable of carrying 12 passengers, not counting the driver. Thanks to its good cross-country ability, the model is often used as a suburban public transport.

Steering gear

Combined with power steering into one unit. The car's power steering reduces the force that must be applied to the steering wheel to turn the front wheels, softens the impacts that occur when the car moves on uneven roads, increases traffic safety, and allows you to maintain control over the direction of the car in the event of a front wheel tire break.

The steering mechanism has two working pairs: a screw with a nut on circulating balls and a piston and rack that engages with the toothed sector of the bipod shaft. The steering gear ratio is 20:1.

The steering gear housing is also a power steering cylinder in which the rack piston moves. The rack and sector teeth have a variable thickness along the length, which allows you to adjust the engagement gap by means of axial movement of the bipod shaft.

The axial position of the bipod shaft is set by an adjusting screw, the head of which fits into the shaft hole and rests on the washer. The axial movement of the adjusting screw relative to the bipod after assembly should be 0.02....0.08 mm. The bipod is installed on the shaft according to the marks.

Summing up

As a result, we can say that the steering unit in a car is the main component of the entire mechanism. Do not postpone repair work and diagnostics if any deviations appear. At the slightest incomprehensible sound or vibration, you need to go to a service station and get a diagnosis done.

Because this barely audible sound while the car is moving can turn into a big problem, especially if the Volga is driving at high speed along the highway.

Electrical circuit diagrams for the PAZ-32053 bus

The air supply to the brake mechanism is carried out by Fig.

A positive potential is formed at the emitter of transistor T1 relative to its base, and it closes. When the measurement voltage is 24 V, the test lamp should light up, since transistor G4 is open to full excitation. Checking other electrical appliances and equipment Electrical signal beeps.

Buses typically use acid-acid batteries. Trouble-free operation and accuracy of instrument readings can only be ensured if the electrical contacts are perfect, therefore, every time the instrument panel has been removed for any reason, the fastening of the instruments and wire fixing screws should be checked and, if necessary, tightened.

When the doors are opened, the switches automatically close the power supply circuit for the lights. The prescribed colors for them are clear, white or orange, only red is allowed at the back. Typically, the flashing frequency is 60 min-1; — the serviceability of the turn relay is checked by removing one lamp; if the flashing frequency does not change, the relay is faulty.

The sound signal and instrument lighting should be checked during regular maintenance. The generator is excited by the central switch through the charging indicator lamp, so a prerequisite is the constant serviceability of this lamp. In this way, not only the activation of the alarm is monitored, but also the serviceability of all lights.

The brake signal lights 6 are turned on by relay K4 of block 1. The assessment of the starter state may be incorrect if the voltage drop in all starting circuits exceeds the permissible limit.

Turn signal and hazard warning lights. Executive relay P1 is de-energized and its contacts are open. The voltage regulation of an alternating current generator, like that of a direct current generator, is carried out by regulating the excitation current. The protection circuit works as follows. The operation of the system is ensured by a unified contact-transistor relay-breaker.

Typically, a so-called load fork is used for measurements. Anti-lock brake system diagram on page This relay has two windings with one controlled contact pair. Sometimes it becomes necessary to turn the headlight in a vertical plane perpendicular to the direction of movement, since the reflected line delimiting the light and dark zones converges with the reference line on the screen at an angle.
