Maintenance, repair

Of all the car’s electrical appliances, only power supplies require maintenance:

Battery (periodic recharging using chargers, monitoring the level and density of the electrolyte);
Generator (periodic check of drive tension, replacement of worn graphite brushes).

It is also important to monitor the condition of the wire insulation and prevent it from being damaged to avoid a short circuit. Oxidation of contacts often occurs at the wiring junctions, which can lead to failure of electrical appliances.

Most of the electrical network components are maintenance-free and must be replaced if they fail. Such elements include light bulbs, small electric motors, switches, relays, fuses, and sensors.

In the starter, generator, electric. In the heater and cooling system fan motors, mechanical breakdowns may occur - wear of bearings, bushings, brushes. All these components are repairable and it is often possible to restore their functionality by disassembling, troubleshooting and installing new parts to replace worn ones.

Common electrical faults

Common problems with electrical equipment on VAZ-1111 and 1113:

Failure of external lighting devices. A common cause of failure is burnt out lamp filament; the unit must be replaced. If the light bulb is intact, then there may be a defect in the electrical wiring, due to which a short circuit occurs and the fuse fails. The fuse link is replaced with an identical one; it is prohibited to use parts designed for a higher current. It is also unacceptable to install homemade jumpers (“bugs”), as this can cause a fire. If a repeated burnout occurs, it is necessary to check the circuit and eliminate the wiring fault.
Wire breaks occur at points where the insulation is subject to bending or friction against moving surfaces. An example of such a point is the junction of the door and the body. Damaged areas must be replaced with products made of similar material with an identical cross-section.
Oxidation of contact surfaces due to moisture or aggressive liquids (for example, battery electrolyte). It is necessary to clean the surfaces down to metal, restoring the transmission of electric current.
Relay failure associated with burnt contacts or coil breakage. The unit cannot be repaired; it must be replaced with a new one. In the event of a rapid re-failure, the vehicle's electrical system must be checked at a car service center.
Sudden battery discharge is due to an internal short or current leakage. In winter, a partially charged battery may lose capacity due to low air temperatures. You need to charge the battery and check the condition of the wiring. If necessary, the power source must be replaced.
Pulsating operation of external lighting lamps with an unusually bright glow indicates a breakdown of the relay regulator on the generator. Repair requires removing the unit and replacing failed components.
Insufficient battery charge (the warning light does not go out when the engine is running). The cause may be wear on the brushes or commutator, or insufficient tension on the drive belt. The generator needs to be repaired, since the battery charge is enough for 150-200 km during the daytime.
Poor contact between the ends of the cylindrical fuses and the spring-loaded elements in the mounting block. It arises due to the design features of the unit. Many owners, tired of dealing with the defect, install homemade blocks for knife inserts. Usually a short section from the GAZ-3110 is used, designed for 13 seats. There are self-assembled units designed for fuses and relays.

Starter relay VAZ-1111
Heated rear window relay

The front wiper relay (RS-514 (2101-5205150)) is located under the upholstery, left side panel. The parking brake warning lamp relay (RS-492 (2101-3803150)) is located behind the instrument cluster, next to the turn signal relay. The ignition relay (90.3747-10 / 113.3747-10 / 2105-3747210-20) is secured with a self-tapping screw from inside the instrument panel. The hazard warning and direction indicator relay (494.3747 / 2105-3747010-01) is located behind the instrument cluster.

Separation by purpose

By purpose, the equipment is divided into:

Power supplies;
Protective means;
Controls;
Instrumentation;
Actuators;

Some circuit components have dual purposes. These include relays, which are both control elements and protective devices.

Power supplies

Power sources include the battery and generator. The battery powers the electricity. devices and ensures their operation when the power unit is turned off. After starting the engine, the on-board network is powered from the generator, which also ensures that the battery is recharged.

Protective components

Protective means prevent burnout of electrical appliances and electrical circuits during short circuits. The main protective elements are fuses. For convenience, all protective elements are collected in one place - the fuse box, which in Oka is located under the front panel on the driver’s side.

Controls

Control elements include all components responsible for turning on, switching and turning off electrical appliances. This category combines the ignition switch, all kinds of switches and switches. Most of these elements are located within direct reach of the driver - on the front panel, steering column. But there are switches that the driver acts on through certain components - brake light switches, a sensor for turning on the choke warning light, etc.

instrumentation

Control and measuring devices provide the driver with information about the operation of certain components and mechanisms, operational indicators - fuel level, coolant temperature, oil pressure, etc. Some types of these devices display accurate information, while others are presented in the form of warning lamps that are triggered only when an emergency occurs. malfunctions.

Measuring instruments combine sensors installed on the required components and mechanisms, and signal elements located on the dashboard.

Actuating devices

Actuators are components that perform one or another function - they illuminate, operate components, etc. These include electric motors, lighting lamps, a sound signal, a cigarette lighter, etc.

Basic Switch Elements

The switch circuit is quite simple, but making this unit yourself is pointless, since buying a ready-made version will be much easier. Installation must be carried out as competently as possible, otherwise the device will not operate correctly. In addition, when using transistors, you need to carefully select them according to their parameters, and for this you need to have high-quality measuring equipment. Unfortunately, for two identical semiconductors, the spread of characteristics can be very large. And this affects the operation of the device.

The switch is. Switch diagram. How to check the ignition switch

The switch is an electronic component to ensure the operation of a contactless ignition system. It is transitional between contact and microprocessor. The latter, the most advanced, allows you to control the torque using data read from sensors - oxygen, speed, engine speed and others. But there are still many cars on the roads that have both contact breakers and contactless ones. Therefore, for maintenance and diagnostics, you need to know the purpose of all elements, as well as troubleshooting methods and their main symptoms. Before testing the switch, review all parts carefully.
