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.
IMPORTANT: Always store spare fuses in the boat for replacement.
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 dealer.
A circuit breaker provides protection for the engine wiring harness and the instrumentation
power lead. Test the circuit breaker by pushing the red button. If the circuit breaker is
functioning properly, the yellow lever appears. Push the yellow lever into the housing to
reset the circuit breaker.
