A control apparatus for an AC generator is disclosed in which a storage battery is connected to the field coil of the generator for supplying a current to the field coil, the battery being also connected through the rectifier to the armature coil of the generator so as to be thereby charged through the rectifier. A voltage regulator is connected between the generator and the battery for controlling the current supply from the battery to the field coil, the voltage regulator including a switch connected in series with the filed coil of the generator for turning on and off the current supply from the storage battery to the field coil so as to control the output voltage of the generator to a predetermined value. A detector is connected between the armature coil of the generator and the storage battery and between the rectifier and the storage battery for detecting the operating state of the generator and operating an indicator so as to indicate the detected operating state of the generator. The detector includes an indicator switch for turning the indicator on and off, an emitter follower transistor connected through the rectifier to the armature coil of the generator for switching over the indicator switch based on the generation signal from the armature coil, and a capacitor connected to the emitter follower transistor for smoothing the generation signal from the armature coil. In a preferred form, an adjuster is connected between the voltage regulator and the detector for detecting the output voltage of the emitter follower transistor and adjusting it to a value lower than the predetermined value to which the output voltage of the generator is controlled by the voltage regulator.
