6.7 DC Circuit Protection
General
Power is distributed to most of the 12 volt acces-
sories through individual “push to reset” circuit
breakers located the battery switch panel in the
head compartment or fuses in panels near the
battery switches. A heavy duty, main circuit
breaker near the battery switches protects the
system from an overload. Other heavy duty circuit
breakers near the battery switches protect the
main circuits for the windlass and stereo amplier.
There could also be circuit breakers for the igni-
tion systems, auxiliary charging circuits and power
steering assist pump. The breaker protection will
vary with the engine options selected.
Some 12 volt accessories are operated directly by
the circuit breaker or fuse. Switches fed by the cir-
cuit breakers or fuses activate other accessories.
Accessory Breakers and Fuses
Circuit breakers or fuses are labeled for the acces-
sory circuit they protect. Circuit breakers labeled
ACC are reserved for additional accessories not
usually installed by the factory.

If an accessory breaker trips, the reset button
pops out and can be felt through the silicone pro-
tective cover. Press the button to reset the tripped
breaker. If the breaker trips again, nd and cor-
rect the problem before resetting the breaker.
If a fuse blows, it must be replaced with a fuse
of the same amperage as the original. The fuses
are labeled and some are color coded. Never try
to correct a problem with a 12 volt accessory
by installing a larger fuse. This could cause the
accessory or circuit with a problem to overheat,
which could result in an electrical re.
PROPER FUSE OR BREAKER PROTECTION MUST BE
PROVIDED FOR ALL 12 VOLT EQUIPMENT ADDED. DO
NOT OVERLOAD THE ACCESSORY CIRCUIT BREAKERS
OR OTHER CIRCUITRY THROUGH ADDITIONAL 12 VOLT
EQUIPMENT.
