Abstract
A controller of a generator for a vehicle in the invention includes a battery voltage detecting circuit and an output terminal voltage detecting circuit of an AC generator. A value of a detected voltage of the output terminal voltage of the AC generator is set to be higher than a value of a detected voltage of the battery voltage. A diagnosis alarm signal is outputted when the detected voltage of the battery voltage is lower than the set value while the detected voltage of the output terminal is higher than the set value.
Claims6
A controller of an AC generator for a vehicle for rectifying an output of the AC generator and supplying an electric load with electric power, the controller comprising:
- a battery voltage detecting circuit for detecting a charging voltage of the battery;
- and
- an output voltage detecting circuit for detecting the output terminal voltage of the AC generator, wherein
- a detected voltage value of the output terminal voltage of the AC generator is set to be higher than a detected voltage value of the battery voltage and
- a diagnosis alarm signal is outputted when a detected voltage of the battery voltage is lower than the set value and a detected voltage of the output terminal voltage is higher than the set value.
