Section 7
Electrical Systems
Your motor home is equipped with an electrical system consisting of two separate voltages; a 12-volt DC
system and a 110-volt AC system. The 12-volt system consists of two internal power sources, while the 110-
volt system is operated from an outside power source or the optional 110-volt generator. All systems operate
through a single power converter control center to provide electrical power to the motor home.
110-VOLT AC SYSTEM
The 110-volt system operates from an outside 110-volt utility service such as those at campgrounds, or from
the optional 110-volt generator. When the power cord is connected to an outside power source, or when the
generator is in operations, the power converter automatically changes a portion of the 110-volt current to 12-
volt DC current. All equipment in the motor home that is normally powered by the auxiliary battery is then
powered through the converter.
In addition, the following equipment is entirely dependent on 110-volt current: roof air conditioner,
refrigerator (when placed in AC mode), microwave oven, and any 110-volt electrical equipment used at
convenience outlets.
EXTERNAL POWER CORD (SHORELINE)
The external detachable 30amp utility power cord (commonly referred to as a “shoreline”) is stored in the
one of the exterior compartments in the coach.
WARNING
Do not connect
the external power cord to any receptacle
until
you have contacted the owner
and/or attendant of the premises to verify proper polarity and grounding.
It is the responsibility of the owner of the electrical receptacle to ensure that the receptacle is
properly wired and grounded.
Reverse polarity and improper grounding of the vehicle can cause personal injury or death.
To connect to an external power source, remove the cord from the storage compartment and plug it into and
secure it to the exterior connection on the motorhome and the other end to a suitable power receptacle.
The three-prong power cord is designed to ground the electrical system through the receptacle. It is also
designed to carry the amperage output of most campground outlets. If the electrical receptacle to be used is
designed to mate with the three prongs on the power cord plug, the electrical connection can be expected to
carry rated load.
WARNING
Do not
plug the power cord into an outlet that is not grounded, or adapt the plug to connect to a
receptacle for which it is not designed.
Be sure that all three prongs of the supply cord are properly plugged into the receptacle.
Do not
plug the power cord in while the generator is already running if so equipped.
