This section contains information, guidelines
and procedures on the operation of the house
electrical system. 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, 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 Volt AC and
12 Volt DC.
The motorhome 120 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. Two different sources supply the
main AC circuit breaker panel with power: the
shore power cord or the on-board generator.
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 supply charge
voltage to the house batteries. Conversely,
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 front electrical
panel and 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 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.
