The circuitry within the device prevents back
feeding of electricity from the chassis to coach
battery so if 120-volt power is interrupted, the
chassis battery will not be discharged.
House Batteries
The house batteries supply current to 12-volt
equipment located in the living area of the coach.
This includes interior lights, range exhaust fan,
water pump, water level and holding tank gauges,
120-volt generator starter, refrigerator, and bath
roof vent fan. The house battery may also be used
to start the engine if the automotive battery is
discharged. (See "House/Coach Battery
Disconnect switch" or "Battery Boost switch" in
Section 3 - Driving Your Motor Home).
The house batteries are automatically charged
by the chassis alternator while the engine is
running.
NOTE: House batteries are AGM (Absorbed
Glass Mat). Because of their
construction, AGM batteries do not
require an addition of water to the cells.
HOUSE/COACH BATTERY
DISCONNECT SWITCH
The House/Coach Battery Disconnect switch
disconnects the house batteries from the 12-volt
system of your coach during storage periods to
avoid battery drain by electrical items that are
hooked directly to the house batteries, such as
clock displays and radio memories, etc.
Always leave this switch ON while using the
coach.
NOTE: Some electronic displays and memory
functions may need to be reset after
power has been reconnected.
See also "Battery Care" elsewhere in this
section.
House/Coach Battery Disconnect Switch
(Located near entrance door)
-Typical View
• These switches illuminate when the House/Coach
Battery Disconnect switch is ON.
NOTICE
If the House/Coach Battery Disconnect
switch is OFF when 120-volt AC current is
present (from either the auxiliary
generator or shoreline), the green
indicator lamp on the disconnect switch
will be illuminated, but the house batteries
will not be connected and will not be
recharged. The coach is not intended to
be used in this manner. Always switch
the House/Coach Battery Disconnect
switch to ON when 120-volt AC current
is present.
BATTERY ACCESS
House/Coach Batteries
The house/coach batteries are located within
the basement of the coach, which is accessible
through a removable floor panel inside driver and
passenger side mid-coach compartment doors.
