ABSTRACT:
A generator voltage control apparatus includes a generator with a field coil and a battery which is charged by the output of the generator. A first transistor is provided for controlling the current passed through the field coil to maintain constant the voltage of the generator. A charge display lamp is connected in series to the first transistor. A second transistor is connected in parallel to the charge display lamp connected in series so that the second transistor is turned on by a voltage generated by the generator and is turned off by an overvoltage generated thereby.
