The purpose of the regulator is to limit the amount of current flowing in the generator field windings. There is basically three windings or parts to the regulator:
Cutout Relay - Controls the current between the generator and the battery. It closes the circuit when the generator is producing current. When the engine is off, it opens the circuit to prevent battery drain through the generator.
Current Regulator - Keeps the generator output withing the maximum level by rapidly opening and closing points based on circuit demands. For examplr, when you have a low charged battery, this winding kicks in to cause the generator to produce maximum output to charge the bateery and run circuit components, ignition, lights and accessories.
Voltage Regulator - Reduces the generator output level based on circuit demands. For example, once the battery charge level is increased, the current regulator kicks off, and the voltage regulator takes over to regulate the circuit based on demand.
