ABSTRACT:
A voltage regulator includes a first normally closed switch arranged for releasably connecting the field coil terminal of an engine-driven DC alternator or DC generator to its appropriate positive or negative output terminal. The first switch is controlled by an electric actuator having an electric circuit arranged for connection across the output terminals of the alternator or generator and is operable at a predetermined lower 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 significant consumption of water. A second switch in the electric circuit of the first switch actuator is controlled by an electric actuator arranged for connection across the output terminals of the alternator or generator and is operable at a predetermined higher level output voltage to close the second switch and activate the first switch actuator to open the first switch and reduce the charging voltage to said lower level from 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.
