ELECTRICAL SYSTEMS
12-VOLT DC SYSTEM
The DC voltage system consists of the auto-
motive batteries and the 12-volt coach auxiliary
batteries.
Auxiliary Battery (Aux. Batt) Switch
The AUX BATT switch disconnects the aux-
iliary (coach) batteries from the 12-volt system of
your coach to avoid long-term battery drain by
electrical items that are hooked directly to the
coach batteries, such as clock displays and radio
memories, etc.
Always leave this switch ON except during
storage periods. Some electronic displays and
memory functions may need to be reset after
power has been reconnected.

12-VOLT CIRCUIT BREAKERS
All 12-volt circuits and equipment in the
coach area of the motor home are protected by a
circuit breaker panel. When a circuit is over-
loaded or a short developed in any part of the
system, a breaker will shut down that circuit. If
this happens, turn off all affected lights or appli-
ances and reset the breaker.
A label on the panel states the amperage rat-
ing and circuit protected for each breaker.
The House 12-Volt Breaker Panel is located
behind the small cabinet door near the galley or
below the refrigerator.

The voltage inverter changes 12 volt DC cur-
rent into 110 volt AC current to operate your TV
and DVD/VCP while traveling or when shoreline
hookup is not available.
