12-Volt DC System
The majority of your recreation vehicle lighting is powered by 12-volt electricity. The 12-
volt DC system is composed of components that will operate when the following conditions
are met:
Power is supplied by the tow vehicle alternator when the engine is running and the
7-way trailer plug is connected. This powers the RV’s running lights, brake lights,
turn signals and brakes. In addition, the 7-way trailer plug provides a common
ground and a 12-volt charge line to charge the auxiliary battery.
The converter will supply interior 12-volt DC power when the power cord is
plugged into campground power. The converter will also charge the RV battery in
most situations. (Refer to
Battery Disconnec
t)
The auxiliary battery powers many interior 12-volt components including the
lighting fixtures, water pump, 12-volt motors, 12-volt appliances, etc. It also pow
-
ers the breakaway switch.
12-Volt Fuse Panel
The 12-volt fuse panel is labeled to indicate fuse sizes, positions and the components pow-
ered.
Fuses are located in the load center.
Replacing A Fuse
Before replacing a fuse, always turn off the electrical components protected by it.
1.
Disconnect the shore power cord.
2.
Turn “off” the inverter (if so equipped).
3.
Disconnect the house or auxiliary batteries main negative battery cable.
4.
Remove the fuse panel cover to check fuses.
5.
Pull the fuse straight out of the fuse block.
6.
Insert a new fuse of the same specified voltage, amperage rating and type in the original
location.
The fuse panel label should be kept permanently affixed to your recreation vehicle. Fuses
will not offer complete protection of the electrical system in the event of a power surge or
spike.
12-Volt DC Outlet
There may be one or more 12-volt DC power outlets in your recreation vehicle. When the
12-volt DC outlet is used as a power source for an electric appliance, make sure the appli-
ance operates on 12-volt DC power and that it consumes less than 60 watts (5 amps) of
power.
Keep the protective dust cap on the 12-volt DC outlet when not in use to pre-
vent ingestion of foreign material and potential short circuit conditions.
Replacement fuses must be of the same voltage, amperage rating and type.
Never use a higher rated replacement fuse;
doing so may cause a fire by
overheating the RV wiring.
