Powered Alternator

Have you ever wondered what part your car can't work without? The answer is one word ALTERNATOR.

The alternator constantly produces the required amount of electricity to power all consumers, while also storing its surplus in the battery and replenishing it. Today, all cars have alternators because they have the ability to generate enough electricity to charge the battery at the lowest RPM.

The alternator components are:

rotor
stator
electronic voltage regulator-regler
rectifier
housing
bearings

In order for the alternator to function, it must be driven by a gear belt over the crankshaft. Before every check we will check the belt or sprocket.

See the ALTERNATORS category

As the alternator supplies power to the vehicle's electrical system when the engine is running, and with excess energy it replenishes the battery first, we can check that the charging voltage on the battery is within the required range. The charging voltage must be between 13.8 and 14.7 V. If the voltage is lower or higher, the voltage regulator is malfunctioning.

The cause of the instrument lamp on the instrument panel may be a faulty voltage regulator or controller, wear of its brushes or failure of the electronic part of the controller. In some cases, brushes can be replaced and the cost of repair reduced, but most often the entire regler needs to be replaced. During the aforementioned failure, the intensity of the lamp in the engine operation will be more pronounced red. If the indicator light is not bright, then the diodes may be a problem, then open the bonnet and check the battery's upper surface, which must not be damp. If so, the acid is ejected from the battery due to overcharging and the regler needs to be replaced. If you do this yourself, be sure to disconnect the battery cables to avoid further damage to the car or better, see a professional.
