ABSTRACT:
An apparatus for controlling a charging generator having armature coils and a field coil includes a rectifier for rectifying an a.c. output induced in the armature coils, the rectifier having a first rectifier output terminal, a second rectifier output terminal, and a ground terminal. The control apparatus has a storage battery chargeable with an output from the first rectifier output terminal, a voltage regulator for turning a current flowing from the second rectifier output terminal to the field coil on and off to control an output voltage from the charging generator to a first preset value, and a charging indicator lamp and a switch device which are connected in series between the storage battery and the second rectifier output terminal through a key-operated switch. A diagnostic device detects the absence of power generation by the charging generator by establishing a second preset voltage value lower than the first preset value, detects an uncontrolled voltage output and disconnection of the first rectifier output terminal by establishing a third preset voltage value higher than the first preset value, and energizes the charging indicator lamp in response to such detected malfunctions.
