General description of electrical equipment (Peugeot 305)

The electrical system of a car consists of three main components: (1) battery, (2) generator with voltage regulator and (3) starter. The remaining electrical equipment can be divided into 3 main groups: (1) lighting system, (2) auxiliary electrical equipment and (3) instruments and signal lamps.

The battery supplies the current needed to start the engine, operate the ignition system, lighting, etc., and provides backup power in case the current draw exceeds the generator's capacity.

The generator generates the electrical current necessary to keep the battery charged and to operate auxiliary electrical equipment.

The starter cranks the engine with the help of a pinion gear that meshes with the flywheel ring gear. The starter draws a very high current, and therefore it is connected directly to the battery using a special wire.

When charging the battery, it is necessary to disconnect the wires from its terminals, because. otherwise, you may damage the generator's internal diodes and other semiconductor equipment that may be used on the machine.

The electrical system has a negative "earth", which must be remembered when connecting the radio and other additional electrical equipment.

When starting the engine "smoking" Batteries are connected first with a positive and only then with a negative wire. Disconnecting the wires must be done in reverse order.
