The MotorHome living area electrical system is
designed for utmost convenience. It is capable of
supplying the vehicle with power from at least two
sources (three, if equipped with a motor generator),
these are the batteries or external power.
All electrical components except the water
heater, the roof mounted air conditioner
(if
equipped), and the plug receptacles, are powered by
the 12 volt living area battery which is automatically
charged each time the vehicle's engine is running.
In addition, the vehicle may be plugged into a
120-volt external power source which will supply
120-volt power throughout the living area., power all
12-VOLT LIVING AREA FUSE
BLOCK
The 12-volt living area fuse block is located in the
electrical compartment, next to the hall closet, along
with power converter and main circuit breaker
panel. (figure 1) In the event of an overloaded circuit,
the cause should be corrected and a new fuse of the
same capacity installed. For explanation of 12-volt
fuse block number code, refer to Figure 2 or the
Specifications at the end of this section.
GENERAL INFORMATION
LIVING AREA ELECTRICAL 24B- 1
12-volt components through a power converter, and
charge the living area battery.
If the MotorHome is equipped with a motor gen-
erator, the vehicle will be supplied with 120-volt and
12-volt power throughout the living area, and the
living area battery will be recharged any time the
power converter and motor generator are running.
Both the 12-volt DC and 120-volt AC circuits in
the Motor Home living area are designed to be pro-
tected by a series of fuses and circuit breakers . The
12-volt living area circuits are protected by automo-
tive-type fuses, and the 120-volt circuits are pro-
tected by circuit breakers like those found in modern
homes.
ELECTRICAL COMPARTMENT (FIGURE 1)
120-VOLT CIRCUIT BREAKER
PANEL
The main circuit breaker panel, also located in
the living area electrical compartment, contains cir-
cuit breakers to protect the 120-volt MotorHome
circuits from overloads. These circuit breakers are
designed to snap to the center position in the event
of an overloaded 120-volt circuit. Once the cause of
the overload is corrected the circuit breaker switch
may be moved back to the "ON" position .
