Electrical System Overload Protection‑Carbureted Engines
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 dealer.
1. A circuit breaker provides protection for the engine wiring harness and the
instrumentation power lead. The circuit breaker can be tested by pushing the red
button. If the circuit breaker is functioning properly, the yellow lever will appear. Reset
the yellow lever after testing, or if tripped, by pushing the yellow lever back into the
housing.
