m. BILGE PUMP.
The bilge pump is used to evacuate water from the engine compartment, usually after fording. The bilge pump
should not be operated for more than one minute in a dry compartment or 15 minutes in a flooded compartment,
unless the engine is running.
The bilge pump system consists of the bilge pump, bilge pump relay, bilge pump circuit breaker, circuit breaker
2, and associated wiring.
To operate the bilge pump, the MASTER switch must be turned ON. By turning on the MASTER switch, 24
vdc is supplied from the batteries through the MASTER relay, to circuit breaker 2. From circuit breaker 2, the
voltage is routed to the bilge pump switch. When the bilge pump switch is turned on, power is supplies through
the bilge pump circuit breaker to the bilge pump relay. The bilge pump relay sends the power to the bilge pump
and the bilge pump is energized.
