BATTERY DISCONNECT SWITCH
The 12 volt DC electrical supply to the coach portion of
the motorhome is controlled by the battery disconnect
switch located in the coach doorway. The switch
reduces the demand on the coach batteries to a limited
residual draw when the motorhome is not in use or in
short-term storage. Rotate the switch to the 12 o’clock
position

ELECTRICAL SYSTEM
OPERATION
ELECTRICAL SUPPLY
Your motorhome is equipped with two electrical
systems that operate on separate voltages: an
internal 12 volt DC system (coach batteries) and an
external 120 volt AC system (shore power).
The 12 volt DC system draws power from the
engine’s battery and charging system while driving.
When parked, the 12 volt DC system operates from
the coach batteries, from shore power cable through
the inverter/charger or from the generator through
the inverter/charger. The coach batteries charge
automatically when the unit is connected to shore
power or when the engine or generator is running�
The 120 volt AC system operates either from the
optional 120 volt AC generator installed in your
motorhome or from the outside shore power cable
connection. 120 volt inverted AC power is available
in designated receptacles restricted to the inverter
wattage limitations�
Do not connect the external power cord until
you have conrmed the campground has
the proper polarity and grounding. Improper
grounding or reverse polarity may cause
component damage or failure and/or personal
injury or death.
