Accumulator battery
On vehicles with 5-cylinder engines, a battery with a nominal voltage of 12 V and a nominal capacity of 6.3 Ah is installed, on vehicles with 4-cylinder engines and a manual gearbox, a battery with a capacity of 45 Ah is installed, on vehicles with 4-cylinder engines and automatic transmission with a capacity of 54 Ah. The positive terminal of the battery is connected to the starter and through the mounting block to the rest of the electrical equipment.
Always on (regardless of the position of the key in the ignition switch and after removing the key) power supply circuits for side light lamps, a ceiling lamp, luggage compartment lighting, a sound signal, a clock, a cigarette lighter, a radio receiver and a centralized door lock system.
Generator
The cars were equipped with a three-phase Bosch brand alternator with a built-in rectifier unit with nine valves (six rectifier diodes and three additional diodes) and electronic voltage regulator. The stator windings are star connected. The rotor consists of an excitation winding, two slip rings are pressed onto the rotor shaft. The generator is cooled through the holes in the covers and with the help of a fan mounted on the drive pulley. The generator is driven by a V-belt.
