ABSTRACT:
The alternating current output potential of an alternator is rectified by a main rectifier circuit to provide a first charging potential and by an auxiliary rectifier circuit arrangement of the type that is enabled only in response to the presence of electrical enabling signals to provide a second charging potential. The first charging potential is applied across two series connected storage batteries and the second charging potential is applied across only a selected one of batteries. The enabling signals for the auxiliary rectifier circuit arrangement are initiated by a free-running oscillator circuit and circuitry responsive to the potential across the two batteries in series and to the potential across the selected battery is arranged to disable the oscillator circuit when the potential across the selected battery is of magnitude greater than one-half that of the potential across the two series connected batteries.
