ABSTRACT:
A control apparatus for a charging generator capable of detecting a non-generating state, an uncontrolled state, and a state in which there is a break in connection at the primary output terminal of the generator. A bridge rectifier coupled to the outputs of the armature winding of the charging generator provides the output voltage on first and second output terminals. A voltage regulator controls the amount of current flow in the field coil of the generator in response to the voltage produced on the first output terminal. A diagnostic circuit detects conditions of the non-generating state, the uncontrolled state, and a break in connection at the first output terminal, while a start-up detecting circuit detects the start-up condition of the generator. A charge indicator lamp and a switching circuit are connected in series between the first and second output terminals, with the switching circuit being operated by the diagnostic circuit to turn on when any of the failure conditions have been detected and to the start-up detecting circuit for preventing the lamp from being turned on during the start-up condition of the generator.
