ABSTRACT:
A device of indicating the charging state of a battery including a series combination of a diode and an indicating lamp connected between an output terminal of a rectifying means of an alternator and a battery. A first switching means activates the indicating lamp when the battery voltage is less than a first lower predetermined value. A second switching means turns the first switching means off when the battery voltage rises above the first predetermined value. A third switching means reactivates the indicating lamp when the battery voltage exceeds a second higher predetermined value.
