ABSTRACT:
A charge indicator circuit for a battery charging system is disclosed. The battery charging system comprises an alternator, a rectifier, a voltage regulator, and a battery. The rectifier comprises first and second rectified output terminals and a grounded rectified terminal. The field coil of the alternator is supplied by the second rectified output terminal of the rectifier. The regulator is coupled serially with the field coil and cuts off the field current when the voltage sensed at the second rectified output terminal exceeds a first predetermined level. The charge indicator circuit comprises a serial connection of a diode and an indicator lamp coupled between the second rectified output terminal and the battery, and a detector and switching network coupled between the junction between the lamp and the diode and a ground terminal. The detector and switching network detects the voltage at the second rectified output terminal and when the network senses the voltage at the second rectified output terminal to be less than a second predetermined level, which is set lower than the first predetermined level, the network becomes conductive to energize the lamp, which thus indicates the non-charged state of the battery.
