ABSTRACT OF THE DISCLOSURE A voltage regulator includes a first normally closed swi- tch arranged for releasably connecting the field coil terminal of an engine-driven DC alternator or DC generator to its appro- priate positive or negative output terminal. The first switch is controlled by an electric actuator having an electric cir- cuit arranged for connection across the output terminals of the alternator or generator and is operable at a predetermined lo- wer level output voltage to open the first switch, whereby to limit the output charging voltage to said lower level which is predetermined to effect charging of the battery without signi- ficant consumption of water. A second switch in the electric circuit of the first switch actuator is controlled by an elec- tric actuator arranged for connection across the output termi- nals of the alternator or generator and is operable at a pre- determined higher level output voltage to close the second sw- itch and activate the first switch actuator to open the first switch and reduce the charging voltage to said lower level fr- om said higher level which is predetermined to effect charging of the battery quickly, whereupon charging continues at the lower level until the engine is shut down.
