Maintenance
Before using your motorhome, inspect the circuit breakers
and replace them as needed. Test each circuit breaker by
moving the individual switches to the OFF position, and then
back to the ON position. Circuit breakers may degrade over
time and, as part of your motorhome’s maintenance, must be
replaced as needed.
12 Volt Fuse Panel
The circuits that receive power
from the 12 volt DC section
of the Power Load Center are
protected by automotive blade-
type (ATC) fuses. The 12 volts
DC fuse panel label indicates
fuse sizes, positions, and the
electrical components powered
by the 12 volt circuits. To
determine if a fuse has BLOWN
(unable to pass electricity), it
must be pulled from its socket and visually inspected. A blown
fuse will have a distinct, open gap in the wire or conductor
between the fuse blades.
Only replace blown fuses with fuses of the same size and cur-
rent rating of the fuse that was originally supplied in the fuse
socket. Each socket is labeled with the correct current rating.
Replacing any fuse with a higher current rated fuse will create
an unsafe condition, possibly causing circuit damage and a
fire.
A blown fuse indicates a problem with the circuit that is asso-
ciated with the fuse. You must determine the cause and take
corrective actions whenever a fuse is blown. Possible causes of
blown fuses are:
• Too many devices attached to the circuit, causing circuit
overload.
• The circuit may be overloaded by a device that demands
more energy than what the circuit is designed to deliver.
• A short-circuited or defective device attached to the
circuit.
• A short-circuited wire or outlet associated with the
circuit.
Before replacing a fuse always shut OFF the engine, generator,
and all motorhome electrical systems completely. Make sure
the electrical components listed on the fuse label are in the
OFF position:
1. Shut OFF the chassis engine.
2. Disconnect the shore line power cord.
3. Shut the generator OFF (if equipped).
4. Turn the inverter OFF (if equipped).
5. Turn OFF the Master Battery Disconnect Switch.
6. Remove the fuse panel cover.
7. Turn OFF the electrical device identified on the fuse label.
8. Pull the fuse straight out of the fuse block. If inspection of
the fuse confirms that it is not blown, some other electri-
cal problem may exist.
9. Insert a new fuse of the same specified voltage, amperage
rating, and type in the original location. Never use a high-
er rated replacement fuse. Additionally, lower-rated fuses
will likely blow, for they will not allow adequate current
to the device(s) on that circuit.
The fuse panel label should be kept permanently affixed to
your motorhome. The fuses will not offer complete protection
of the motorhome electrical system in the event of a power
surge or spike. Fuses are maintenance components and must
be replaced as needed. Please contact your selling dealer’s
service department for further repair assistance.
Take corrective action to repair any defective electrical circuit
or device. If help is needed, seek assistance or repairs from a
qualified RV electrician or technician.
NOTE: Blade-type fuses come in several sizes; mini,
standard and large. The fuse sockets of the Power
Load Center only accept standard ATC-size blade
type fuses.
Keep a supply of properly rated blade-type fuses on
hand in case a fuse needs to be replaced. Replace-
ment fuses can be obtained at auto parts stores or
auto repair facilities.
Replacement fuses must be of the same voltage,
amperage rating, and type. Never use a higher rated
replacement fuse as it may cause a fire by overheating
your motorhome’s wiring.
