The consumers are connected to the positive power source by a wire, and to the negative power source - through the car body («mass»).
The electrical system is 12 volt negative ground and consists of a battery. generator, starter, electricity consumers and electrical circuits.
The lighting system includes: headlights, taillights, fog lights, turn signals, license plate lights and interior lights.
The battery is charged from the generator. which is driven by a belt from the crankshaft pulley.
In an electrical system, the battery performs three main functions. Firstly, the battery is the source of energy to start the engine. Secondly, it acts as a voltage stabilizer in the system. Thirdly, it can be a source of power supply for a limited time when the electrical load exceeds the output power of the generator.
