ABSTRACT:
A control device for an AC generator having an armature coil and a field coil includes a rectifier for rectifying an AC output of the AC generator, which is driven by an engine, to excite the field coil. A storage battery is adapted to be charged by the rectified output of the AC generator rectified by the rectifier for supplying power to the field coil when the engine is started. A switching element switches over a connecting condition of the storage battery in such a manner that the storage battery is connected through the rectifier to the field coil to supply power to the field coil when the engine is started, the switching element being connected to an AC output of the AC generator for supplying the AC output voltage of the AC generator as a drive voltage to the second switching element. An output-voltage regulating circuit detects an AC output voltage of the AC generator and for intermittently controlling a field current to the field coil to regulate the AC output voltage of the AC generator to a predetermined value. An indicating lamp is connected between the switching element and the storage battery for indicating a state of electricity generation of the AC generator. An indicating-lamp control circuit turns on and off the indicating lamp based on the state of electricity generation of the AC generator.
