Abstract

A vehicular AC generator comprises a resistor for ground one-phase output terminal in an armature coil, a switch for connecting and disconnecting at least one-phase output terminal out of the other phases of the armature coil to and from the ground, and a control unit for controlling the switch. The switch is controlled ON and OFF in accordance with a voltage generated across the resistor. According to this configuration, in the event of occurrence of leakage current in the armature coil, the occurrence of the leakage current is detected based on the voltage generated across the resistor and the switch is closed, whereby the leakage current is allowed to escape to ground and an actual signal from the resistor is detected easily.
