Note: The electrical equipment of the engine management system is discussed in a separate chapter (see "Engine management system").
The car is equipped with a low-maintenance (or unattended) 55 Ah battery. It provides the starter when starting the engine, as well as the car's security system when parked, and the electric door lock drive (central lock) and other electrical equipment when the engine is not running. When the engine is running, electricity is supplied by the generator. Part of the energy produced by the generator is used to recharge the battery.
For most consumers of electrical energy, the supply voltage is supplied via the ignition switch (lock). Switches and switches 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 electrical energy (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 turn signals are also switched on via a relay.
All electrical circuits of the car (except for the power circuits of the starter and generator) protected by fuses.
The fuse's rated operating current is indicated on its body. In addition, the fuse body's color corresponds to a certain current value: 5 A - beige; 7.5 A - brown; 10 A- red; 15 A - blue; 20 A - yellow; 25 A - white; 30 A - green. 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.
