This section contains guidelines, procedures
and information on the electrical system and
operation of various components. Refer to
the OEM manuals included in the Owner’s
Information File box for respective, in-depth,
individual component operating instructions.
General Overview:
The motorhome can utilize various sources
of electrical power: shore power connection,
generator, inverter, chassis batteries and
house batteries. All of these electrical power
sources, while independent of each other, can
be combined in a variety of ways to provide
a highly efficient electrical operating system.
Two types of electrical systems are used:
120/240 Volt AC and 12 Volt DC.
The motorhome 120/240 Volt AC system
can be operated from three different power
sources: shore power, on-board generator or
the inverter. Shore power is the most efficient
and should be used whenever possible. The
generator can be used when shore power is
unavailable. The inverter supplies silent AC
power by using the house batteries to power
select outlets and appliances. However,
inverter AC power output is limited and should
be used sparingly to conserve house battery
power. Two different sources supply the
main AC circuit breaker panel (Load Center)
with power: the 50 Amp shore power cord or
the on-board generator. The transfer switch
automatically selects between shore power and
generator power.
WARNING:
The electrical system is engineered
and tested for safety. Circuit breakers
and fuses protect the electrical circuits
from overloading. When planning
modifications or additions to the
electrical system, ensure safety of the
electrical system. Please note that any
modifications may void the warranty.
WARNING:
Water is electrically conductive. Do
not use any electrically powered item
or outlet that may be exposed to a
water source. Such use can result in a
serious shock causing injury or death.
12 Volt DC System:
The motorhome has two 12 Volt DC systems:
chassis and house. These two systems, for
the most part, are separate from one another.
The house system does not operate engine
functions; the engine system does not operate
house functions. However, within the two
systems there are some inner connections. For
example: While the motorhome is driven the
alternator on the engine will maintain a charge
to the house batteries. Likewise, while the
motorhome is plugged into shore power, or
the generator is running, the chassis batteries
are being charged. Each system will supply 12
Volt DC power to the 12 Volt DC distribution
panels.
Chassis and House System:
The chassis and house systems have their
own sets of batteries. The chassis batteries
supply 12 Volt DC power to the chassis fuse
boxes and the front distribution box. These
panels contain mostly engine system circuits
and wiring such as headlights, taillights,
dashboard functions, gauges, etc. The house
batteries supply 12 Volt DC power to the house
distribution panel. This panel contains fuses
for the house, interior lighting and appliances.
Become familiar with these panels and the
items they operate.
Maintenance:
It is important to keep the 12 Volt DC
systems in good working order as many of
these systems use electronics. These systems,
with their incorporated electronics, are voltage
sensitive. Some items can be damaged if
the DC voltage is not maintained within the
designed specifications.
Why Batteries are Important:
A majority of the lighting and appliances are
designed to operate from 12 Volt DC (direct
current) power. This is why the batteries
play such an important role in the function
of the motorhome. There are exceptions
with appliances such as the microwave or
television; however, indirectly they still
operate from 12 Volt DC power, as they can
be operated from the inverter. The chassis
functions (engine, transmission, dash air, etc.)
are also 12 Volt DC.
