Electrical System Operation

Electrical Supply

This Motorhome is equipped to operate with two electrical
systems operating 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 its power from either
the engine's battery and charging system while driving
or from the coach batteries when parked. An isolator
separates the two battery systems to prevent the engine
battery from being drawn down when parked and the
coach system is in use.
The 12 volt DC System operates from the coach batteries,
from shore power through the converter or from the
generator through the convertor. The coach batteries
are automatically charged when the unit is connected to
shore power, when the engine is running, or when the
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 connection.
Warning
Do not connect the external power cord until you have
checked with the owner/ attendant of the campground
as to proper polarity and grounding. Improper grounding
or reverse polarity can cause component failure, injury,
or death.
Shore Power
To operate on 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 curbside of the coach.
To connect the 30 amp power supply cable, rotate the
cover (1) counter-clockwise and lift up. Insert the power
cable (2) 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. A locking ring (3) can
be used to prevent accidental disconnection.
To connect the 30 amp power supply cable to a standard
15 amp socket, utilize the 15 amp connector cable (4)
(located in a kitchen drawer.)

the 3 o'clock position (5).
