Electrical System Overload Protection
If an electrical overload occurs, a fuse or circuit breaker opens.
Locate and correct the problem before replacing the fuse or
resetting circuit breaker.
• A circuit breaker protects the engine wiring harness and
instrumentation power lead. Reset by pushing the reset
button.
• Four fuses are located at the upper rear of the engine
containing 5 and 15 amp fuses.
