The car has a three-phase alternating current generator. Depending on the model and equipment, generators of different power can be installed.
Caution! If electrical devices with high power consumption are subsequently installed on the vehicle, it is necessary to check whether the power of the existing generator is sufficient. If necessary, a new generator with higher power must be installed.
The alternating voltage created by the generator is converted by the rectifier diodes into direct voltage, which is used to charge the battery. The regulator changes the charging current so that the operating voltage remains constant regardless of the number of revolutions.
Attention! The generator can be replaced. A damaged generator is accepted for credit when purchasing a repaired or new generator. Therefore, take the broken generator with you.
