7.1. General information

Fig. 7.1. System of power supply of the Mazda 6 car: 1–storage battery; 2–generator of an alternating current; 3–starter; 4–ignition coil; 5–spark plug; 6–high-voltage wires

Consumers incorporate to the "plusovy" power supply a wire, and with "minus" - through a car body ("weight"). Such method allows to reduce number of wires and to simplify installation.

The system of electric equipment consists of the storage battery, the generator, a starter, consumers of the electric power and electric chains.

Headlights belong to lighting devices, back lamps, fog lights, turn indexes, lamps of illumination of registration plate and lighting devices of salon.

The storage battery is charged from the generator which is put in action by a belt from a pulley of a cranked shaft.

The starter represents the electric motor of a direct current of smeshanny excitement with the electromagnetic traction relay. At start-up the traction relay enters a leading gear wheel into gearing with a gear wreath of a flywheel before the starter will receive a food from the storage battery. After engine start-up the coupling of a free wheeling disconnects a starter anchor from a gear wreath of a flywheel.

It should be noted that for prevention of short circuit and receiving burns at work with any element of electric equipment of the car always disconnect a wire from the negative plug of the storage battery.
