Pic. 13.1. Location of the main elements of electrical equipment and the ignition system in the engine compartment of the car: 1 - rechargeable battery; 2 - starter; 3 - generator; 4 - high-voltage wires; 5 – breaker-distributor of ignition; 6 – a bolt of fastening of the coil of ignition; 7 - spark plug
The electrical equipment system consists of a battery, a generator, a starter, consumers of electricity and electrical circuits (pic. 13.1).
The lighting system includes headlights, rear lights, fog lights, direction indicators, license plate lights, and interior lights.
The battery is charged by the alternator, which is driven by a belt from the crankshaft pulley.
The starter is a mixed-excitation DC motor with an electromagnetic traction relay. When starting, the traction relay engages the pinion gear with the flywheel ring gear before the starter is powered by the battery. After starting the engine, the freewheel disconnects the starter armature from the flywheel ring gear.
It should be noted that when working with any element of the vehicle's electrical equipment, always disconnect the wire from the negative terminal of the battery to prevent short circuits and burns.
