General description (Opel Ascona C)

The main components of a 12-volt, negative-ground electrical system are a 12-volt battery, an alternator driven by a belt from a pulley on top of the engine, and a starter motor.

The battery provides constant current for ignition, lighting and other electrical circuits, and also provides a power reserve when the amount of current consumed by electrical equipment exceeds that produced by the generator.

The generator is equipped with its own regulator, which ensures high output in the case when the battery is in a weakly charged state and the required current is very high, and vice versa, in the case when the battery is fully charged and the required current is not very high, the regulator will ensure low output of the generator.

When installing electrical equipment on negative ground vehicles, it is very important to ensure proper connections, especially if they contain silicone diodes or transistors, otherwise serious damage can occur to the equipment being installed. Electrical appliances such as radios, tape recorders, electronic y systems, electronic tachometers, etc. should be carefully checked for their polarity before connecting.

It is also very important to always disconnect the battery cables when charging it with a special high-speed charger. If you intend to perform body repairs using electric welding equipment, you must disconnect the alternator, otherwise there is a risk of causing serious damage to it
