Abstract
A control for an electrical charging system for selectively connecting a single alternator with two stator coil sets producing charging current at each of six outputs to the output of a first battery and the output of a second battery serially connected to the first battery output. The control comprises a plurality of switchable full wave bridge rectifiers for connecting each of the alternator outputs to one of the first battery output and the second battery output so that the one battery is charged by the alternators. The switchable rectifiers are alternatively switchably connectable to the other battery output so that the other battery is charged by the alternators. The control also includes a switching circuit for switching first one, and then the next of each of the switchable circuits as the voltage across the other battery is increasingly less than the voltage across the one battery so that the rate of charging of the other battery is determined by the amount the voltage across the other battery is less than the voltage across the one battery.
