Attention! If electrical appliances with a high consumption of electricity are subsequently installed on the vehicle, it is necessary to check whether the power of the existing alternator is sufficient. If necessary, install a new generator of higher power.
The alternating voltage created by the generator is converted by the rectifier diodes into a constant voltage, which charges the battery. The regulator changes the charging current in such a way that the operating voltage is kept constant regardless of the speed.
Attention! The generator can be replaced. Damaged generator when buying a repaired or new generator is taken into account. Therefore, take the failed generator with you.
