PURPOSE:To obtain an output current detector of small size inexpensively by disposing a current detector element for detecting the output current of an automotive generator in an insulating bush for insulation between the output terminals of the generator. CONSTITUTION:An automotive generator 33 consists of an AC generator 34, a rectifier 35, a regulator 15, an output current detector 11, and a resin terminal 39, while the detector 11 is disposed in an insulating bush for insulating between the output terminals of the generator 33. In this structure, the output of the generator 34 is rectified by a rectifier 35 to charge a battery 31 and to supply power to an electric load 32. The detector 11 outputs a voltage equivalent to the output current at this time, the output voltage is amplified by an amplifier 37f, and an F/V converter 37h inputs one phase voltage of the generator 34 as a pulse signal to convert the frequency of the signal to a voltage. A comparator 37i judges whether the speed of the generator 34 and the speed of an engine operating in conjunction with the generator 34 are set value or lower or not from the output voltage of the circuit 37h and a reference voltage V1. |
