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.

WARNING
Do not connect the external power cord until you
have confirmed 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.
SHORE POWER
To operate using shore power, connect the 120 volt
AC power supply cable (stored in the driver’s side rear
exterior storage compartment) to the external receptacle
located on the driver’s side of the motorhome.
To connect the 30 amp power supply cable, rotate the
cover

counterclockwise and lift up. Insert the power
cable

into the socket by aligning the locking tab on
the connector pin with the slot in the socket. Turn the
socket clockwise to lock in place. Use a locking ring

to prevent accidental disconnection.

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
5
to disconnect the batteries. Rotate to 3 o’clock position
6
to connect the batteries.
