Mercury MerCruiser Owner's Manual page 33

NOTE: In an emergency, when the engine must be operated and the cause for the high
current draw (overload) 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 dealer.
1. A circuit breaker protects the engine wiring harness and the instrumentation power
lead. Test the circuit breaker by pushing the red button. To reset the breaker, push the
yellow lever back into the housing.
2. A 90 amp fuse is located on the large post of the starter solenoid. This fuse protects
the engine wiring harness if an electrical overload or a reversed battery condition
occurs.
3. Four fuses are located on the port side of the engine. These fuses protect various
Electronic Fuel Injection (EFI) circuits.
