Note: The electrical equipment of the engine management system is discussed in a separate chapter ("Engine management system").
The car is equipped with a maintenance-free battery with a capacity of 55 Ah. It ensures the operation of the starter when starting the engine, as well as the operation of the car's security system when parked, and the operation of the electric door lock drive (central lock) and other electrical equipment when the engine is not running. While the engine is running, electrical power is supplied by the generator. Part of the energy generated by the generator is used to recharge the battery.
For most electrical consumers, power supply voltage will be supplied through the ignition switch (lock). Switches and toggles for the main and additional electrical equipment are installed on the instrument panel trim, on the central console of the instrument panel and on the steering column.
Power supply chains for powerful consumers of electricity (headlights, windscreen wiper, heated rear window, electric fan of the radiator of the engine cooling system, fog lights) are switched via a relay. The windshield wipers, hazard warning lights and direction indicators are also activated via the relay.
Weight of electrical circuits of the car (except for the power circuits of the starter and generator) protected by fuses.
The rated operating current of the fuse is indicated on its body. In addition, the color of the fuse body corresponds to a specific current value:
- 5 A - beige;
- 7.5 A - brown;
- 10 A - red;
- 15 A - blue;
- 20 A - yellow;
- 25 A - white;
- 30 A - green;
- 50 A - red.
Fuses and relays are installed in the mounting block.
The electrical wiring is assembled into bundles of copper wires with multi-colored insulation.
Most electrical connections of electrical equipment are made on plug-in terminal blocks.
