ABSTRACT:
There is disclosed a testing device for a voltage regulator incorporated in a generator assembly for controlling the output voltage of the generator assembly to a predetermined value, the generator assembly including an AC generator having a field coil and an armature coil, and a rectifier for rectifying the output of the AC generator. The testing device comprises a DC power source, a variable voltage generator for supplying a variable voltage to the input of the voltage regulator, and a resistor connected between the DC power source and the field coil, whereby presence or absence of failures of the voltage regulator may be judged from a magnitude of the input variable voltage and a change in voltage at a junction between the field coil and the resistor, as the input voltage is gradually increased.
