Charging System Components: Generator

The generator is a serviceable component. If there is a diagnosed failure of the generator, it must be replaced as an assembly. The engine drive belt drives the generator. When the rotor is spun, it induces an alternating current (AC) into the stator windings. The AC voltage is then sent through a series of diodes for rectification. The rectified voltage has been converted into a direct current (DC) for use by the vehicle's electrical system to maintain electrical loads and battery charge. The voltage regulator, integral to the generator, controls the output of the generator. It is not serviceable. The voltage regulator controls the amount of current provided to the rotor. If the generator has field control circuit failure, the generator defaults to an output voltage of 13.8 volts.
