The majority of the factory-installed RV 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:
0
Power is supplied by the chassis alternator
when the engine is running.
0
The converter will supply interior 12-volt
DC power when the power cord is plugged
into a 120-volt external power source. The
converter will also charge the battery in
most situations.

The house battery powers many interior
12-volt components including the lighting
fixtures, water pump, 12-volt motors,
12-volt appliances, slide room, etc.
In addition to the 12-volt DC system

ISCONNECT
The 12-volt battery disconnect switch is
located near the entrance door. This
momentary switch controls a latching type
solenoid (located near the house battery),
which connects or disconnects the house
battery dependent upon the number of times it
is pushed. When energized, the battery
disconnect solenoid supplies battery power to
all accessories connected to the house 12-volt
fuse panel. The 12-volt battery disconnect
switch is used to disconnect the motorhome
from house battery power during periods of
storage or during service. The switch must be
located in the ON position for the 12-volt house
electrical system to operate.
The LP leak detector must be connected to a
constant power source. If the 12-volt battery
disconnect is in the OFF position it WILL NOT
PROVIDE power to the LP leak detector.

Your motorhome is equipped with an auxiliary
start switch which can momentarily connect
both the house (coach) and chassis batteries
should the chassis battery become
discharged. To operate depress the “Aux.
Start” switch (located on the front driver’s
dash) and hold. Now, use the ignition key to
start chassis engine. Release the “Aux. Start”
switch after the engine has started.

Your RV has many 12-volt DC loads. When
combined, their total is more than the
converter can produce. High demands for
12-volt power can be met by the house (or
coach) battery for limited periods of time. The
12-volt DC electrical system is designed for
usage with Group 27, deep cycle battery. In a
motorhome, the auxiliary battery is usually
referred to as the house (or coach) battery.
One house battery is installed to provide
temporary 12-volt power when 120-volt power
is not available to operate the power converter.
When drawing energy from the battery,
remember that there is a limited amount of
power available before the battery needs to be
recharged. This house battery is located in the
“house portion” of your motorhome.
To recharge the coach battery
1. When the motorhome engine is running,
the alternator will automatically charge the
coach battery through the auxilliary start
solenoid.
2. When parked at a campsite, plug into
shoreline power. With minimal or low load
on the 12-volt electrical system, the
converter will automatically charge the
house battery. This may take several
hours and depends upon battery condition
and the number of 12-volt devices
operated during the charging period.
Dry camping
Consider the charge condition of the house
battery when dry camping. If the house battery
is not being recharged and power is being
