Electrical System Overload Protection
If an electrical overload occurs, a fuse will blow or the circuit breaker will trip open. The cause
must be found and corrected 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 accessories
connected to the engine and instrumentation wiring. Reset the circuit breaker. If the breaker
remains open, the electrical overload has not been eliminated. Further checks must be
made on the electrical system. Contact your authorized Mercury MerCruiser dealer.
1. A red circuit breaker provides protection for engine wiring harness and the
instrumentation power lead. Reset by pushing the “RESET” button IN.

nothing happens (and circuit breaker is not tripped).
