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.
