The voltage regulator transforms the current generated by the alternator to the right current for your car. This normal voltage is subsequently directed towards energy-consuming components such as the headlights or car radio. The main task of the alternator regulator is to control the alternator. It also ensures that the battery is not overcharged because it keeps getting charged by the dynamo. The alternator voltage regulator furthermore ensures that the electrical components, such as the tail lights, are supplied with the right amount of current. This prevents a short circuit or that parts burn out. Just like most car parts, this part can also break. If it breaks, it is time to replace it.
