Description & Operation

Generator is a 3-phase, field-sensed unit. An electronic voltage regulator controls output voltage by high frequency switching of rotor field circuit. Generator system uses a charge indicator warning light located in instrument panel. When ignition switch is turned to ON position battery voltage is supplied to charge indicator warning light, which illuminates as a bulb check. When generator supplied voltage to charge indicator warning light exceeds battery voltage, charge light ground is cancelled and it will go out. If generator supplied voltage becomes less than battery voltage, charge indicator warning light ground is restored, illuminating bulb to let driver know a malfunction has occurred in charging system.
