CIRCUIT BREAKERS AND FUSES
CIRCUIT BREAKERS
Circuit breakers are resettable electrical circuit
protection devices that stop the
fl
ow of current
in the event of a circuit overload. Once a circuit
breaker is tripped, allow breaker to cool and
then press the reset button to manually reset the
breaker.
If the overload that caused the circuit breaker to
trip is still there, the circuit breaker will continue to
stop current
fl
ow until the problem is corrected.
The circuit breakers are located inside the battery
compartment next to the hour meter.
The chart shows the circuit breakers and the
electrical components they protect.

NOTE: Always replace the fuse with a fuse of the
same amperage.
