SECTION 6
ELECTRICAL SYSTEMS
6-1
(See also Safety Precautions, Section 1 of this
manual.)
Your coach is equipped with an electrical sys-
tem 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 from the
optional 110-volt generator or 110-volt inverter
system.
110-VOLT AC SYSTEM
The 110-volt system operates from an outside
110-volt utility service such as those at camp-
grounds, or from the 110-volt generator or 110-
volt inverter system. When the power cord is
connected to an outside power source, or when
the generator is in operation, the power con-
verter 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: central
air conditioner, refrigerator (when placed in 110-
volt mode), microwave oven, ice maker, vacuum
cleaner and other 110-volt electrical equipment
used at convenience outlets.
EXTERNAL POWER CORD
(Shoreline)
The external utility power cord (commonly re-
ferred to as a “shoreline”) is stored in a utility
compartment on the left (driver’s) side of the
coach.
The 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 prongs of the
power cord plug, the electrical connection can be
expected to carry rated load.
The 50-amp shoreline gives your coach extra
current handling capacity.
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 polar-
ity 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
