Abstract

PURPOSE:To enable an inexpensive device to surely detect an engine to be in operation or stopping by providing a capacitor, which allows a ripple component contained in a charging current to a battery to pass through while inhibiting a DC current from its flow when the engine is in operation, and detecting the ripple component. CONSTITUTION:An output of an AC generator 1, driven by an engine, is rectified but not completely in a charging circuit 2, and in its output current, a ripple component is contained. For detecting this ripple component, lead wires 11a, 11b, having input terminals 10a, 10b connectable to contacts 5a, 5b of a cigar lighter or the like connected to power supply wires 4a, 4b, are provided. And providing a capacitor 12, which allows only the ripple component to flow while inhibiting a DC component, to be interposed in the one lead wire 11a, the picked up ripple component is input to a rectifier-amplifier circuit 13, and a detection signal, obtaining a high level when the engine is in operation, is output to utilization circuits 17, 18 from output terminals 16a, 16b.
