2413- 4 LIVING AREA ELECTRICAL
EXTERNAL POWER
GENERAL INFORMATION
The external utilities compartment located in the
left side of the MotorHome contains the 21 foot
power cord used for external power connections (See
figure 3) .
To make an external power connection, remove
the cord from the compartment and plug it into a
suitable power receptacle . No internal switching is
required . When disconnecting from an external
power source the power cord should be plugged into
the motor generator receptacle within the external
utilities compartment. This connects the motor gen-
erator to the MotorHome electrical system . If the
vehicle is not equipped with a motor generator sim-
ply coil the power cord neatly within the external
utilities compartment.
The MotorHome's external power cord contains
two 120-volt circuits, each rated to carry 40 amperes
total. The electrical connection to be used must be
suitable for these requirements. If the receptacle is
designed to mate with the prongs on the power cord
plug, the electrical connection can be expected to
CARRY RATED LOAD . It is recommended that
the power cord not be plugged in if the receptacle is
not designed for the plug . In this event use the op-
tional motor generator.
CAUTION : If the available power supply is
other than 120/240 volt, 60 cycle rating, or
All the lighting throughout the MotorHome is on
the 12-volt system and is powered by either the living
area battery, the power converter when the vehicle is
connected to an external power source, or when the
motor generator is running (if the vehicle is so
equipped). Some of these lights contain a three-way
switch which allows a choice in the amount of light
given off. The switches to these lights are located on
the light fixture itself.
A panel of light switches is located near the en-
trance door . These switches operate the porch light,
the kitchen sink light, the aisle lights, and the water
pump (figure 4) . The water pump switch is il-
luminated when the pump is turned on .

is not properly grounded, it is essential that
no attempt be made to plug in. The Motor-
Home's electrical system is not designed for
such electrical systems and connection
could result in serious personal injury or
property damage .
CORD REPLACEMENT
Should it ever become necessary to replace the
external power cord for any reason, refer to the 120-
volt wiring diagram later in this manual . Care should
be taken that the new cord is properly wired to panel.
