6. Battery Service
A. General
Twelve-volt DC power is supplied by two pairs of 6-V batteries (four batteries
used). Each pair is connected in series to produce 12-V DC. The two pairs are
connected in parallel to provide maximum amperage for engine cranking. The
12-V DC system provides power for operation of the engine electrical system,
governor system, 400-Hz generator protective relay system, and all DC lights
on the unit.
B. ' Battery Location and Accessibility
Batteries are mounted on a support tray located in the body cn the left side of the
vehicle, just to the rear of the left, front fender (see Fig. 15). They are easily
accessible, by loosening two screw type fasteners and opening two hinged access
doors. Open the left door first.
C. Battery Care
(1) Never allow a battery, which has been removed from the vehicle, to sit on
concrete, ground, or metal unless proper insulation is provided. A wooden
platform or board will provTde sufficient insulation.
