ELECTRICAL SUPPLY SYSTEMS AND COMPONENTS
Four 12-volt batteries, connected in series and parallel, deliver 24
The voltage regulator controls the supply of 24 vdc to the vehicle
vdc to the master relay. The MASTER switch on the drivers con-
electrical systems through the master relay. It also acts as a
trol panel, when turned to ON position, draws 24 vdc from the bat-
charger for the batteries when the engine is operating, keeping the
