    摘要: 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.

    摘要: A generation control apparatus for vehicles comprises a voltage regulator circuit for controlling the generation of power by a vehicle generator. The power is supplied to the voltage regulator circuit through a first circuit including an ignition switch and a second circuit not including the ignition switch. The supply of power through the second circuit is dependent upon the generating condition of the generator thus allowing the control of the power generation by means of the current flowing through a charge indicator even if the detection of the power generation is prevented. In this way, even if a fault such as a break occurs in the first circuit, the generating operation is maintained until the engine is turned off and the generator has stopped.
