Controller AC generator for vehicle
First Claim
1. A vehicle AC-generator controller characterized by:
- a storage battery to be charged by a rectification output of an AC generator having a field coil;
a voltage regulator for controlling an output voltage of the AC generator to a predetermined value by controlling a field current flowing through the field coil;
detection means for detecting a power-generation state and a no-power-generation state of the AC generator;
an indicator lamp for indicating the power-generation state and the no-power-generation state of the AC generator;
indicator-lamp driving means for turning on and off the indicator lamp in accordance with the detection result of the detection means;
power-supply driving means for driving a power-supply circuit of the voltage regulator in accordance a turn-on-lamp output of the indicator-lamp driving means; and
power-supply cutoff means for cutting off the power-supply driving means by controlling the turn-on-lamp output to a ground potential when the AC generator is brought into the no-power-generation state.
