12 VOLT SYSTEM FUSES
Interior
A 12 Volt DC distribution panel is located next to the 120 Volt circuit breakers. The panel contains circuits with
replaceable fuses for protection of motor home 12 Volt lines. If any line is shorted, the fuse will ‘"blow". Replace
the fuse with the same size fuse. DO NOT replace with a larger fuse than indicated.
If this action does not solve the problem, there may be a "short" somewhere along the 12 Volt line, or at a
non-fused 12 Volt component on the line. Check the 12 Volt line and any components along the line. Locate
the “short” and take necessary steps to repair it. If you cannot locate the problem, have a qualified electrician
check it out.
It is a good idea to keep additional fuses on hand in the motor home. Replacement fuses are available at filling
stations, hardware stores, or automotive supply stores. Remember that the replacement fuse must be the
same amperage rating as the original.
automotive
Your motor home chassis is equipped with an automotive 12 Volt fuse panel located below the dash near the
steering column and/or under the hood. You should refer to the chassis owner’s manual for details on these
fuses.
The Class A motor home also has a 12 Volt fuse panel, electrical distribution box, located on the fire wall under
the hood. These fuses protect the automotive features which are installed by Thor Motor Coach. There is a
complete breakdown on the various fuses printed on the backside of this fuse panel cover. The class C fuse
panel can be located under the bed, in the dinette base or kitchen base, depending on the model of your motor
home.
CIRCUIT BREAKERS
The 120 Volt system is protected by circuit breakers which automatically shut the circuit off if the circuit load
is too heavy, or a short circuit occurs. If a circuit breaker has been tripped, do not reset the breaker until the
cause of the problem is identified and corrected.
The generator also has one or two AC circuit breakers, and a DC fuse on the generator control panel. If
an interruption in generator operations occurs, check to see if any of these have been tripped. Consult the
manuals provided with the generator before attempting maintenance on the generator.
Note:
Some electrical appliances may have their own circuit breakers. If there is an
interruption in electrical service of an appliance, consult the manual for that
appliance to determine what action to take.
