the power plant compartment. A coolant pump circulates coolant through tubing to
the engine and battery box heat exchanger. The control box is mounted to the left of
the driver. It has a three-position RUN-OFF-START switch, HI-LO switch, and
indicator light. Coolant shutoff valves, at heater and engine block, control flow of
coolant into heater.
