Abstract
A generator operation indicating apparatus for vehicle generators having a protective circuit against abnormal voltage, includes a drive circuit for turning an indicating device on from the time of closing of a key switch until the time that a vehicle generator attains a predetermined operating condition to indicate the generator operation and a control circuit for forcibly rendering the drive circuit inoperative in response to the occurrence of an abnormal voltage between the indicating device and the drive circuit. When the generator attains the predetermined operating condition, the indicating device is turned off and the supply of current to a load circuit is started. In this case, the drive circuit is also forced to come out of operation upon occurrance of an abnormal supply voltage.
