All alternators Possess a voltage regulator circuit which keeps the voltage at The best 13.eight to fourteen.two volts necessary to operate the vehicle and cost the battery. Most more recent autos Have a very voltage regulator that's A part of the alternator, but more mature autos contain the regulator for a separate aspect.
