Overload Protection—Port Side Power Distribution Box
If an electrical overload occurs, a fuse will burn out (blow) or a circuit breaker will trip open. Find and correct the cause for the
electrical overload before replacing the fuse or resetting the circuit breaker.
NOTE: In an emergency, when the engine must be operated and the cause for the high current draw cannot be located and
corrected, turn off or disconnect all the accessories connected to the engine and instrumentation wiring. The circuit breaker
should automatically reset. If the breaker remains open, the electrical overload has not been eliminated. Further checks must
be made on the electrical system. Contact your Mercury Diesel authorized repair facility.
Circuit breakers provide protection for the engine electrical system as indicated. The circuit breaker panel is located within a
power distribution box mounted on the engine control module.
After finding and correcting the cause of the overload, connect the starting battery and turn the ignition switch to the run
position. The circuit breaker should automatically reset. If a circuit breaker fails to reset, contact your Mercury Diesel authorized
repair facility.
