This section contains guidelines, procedures
and information that will assist in understanding
the chassis electrical system and the operation of
various components. Refer to the OEM manuals
included in the Owner’s Information File box for
their respective, in-depth, individual component
operating instructions.
Battery DISconnect
Chassis
The chassis battery
disconnect is located on
in the curbside battery
compartment. The switch
controls the DC power to
the front electrical bay. Most chassis
and engine functions are interrupted when the
battery disconnect is turned off. Some electronic
components of the engine and transmission
require a constant power source and will
continue to draw power when the disconnect is
engaged.
Turn the chassis battery disconnect switch
off when the motorhome is going to be stored
or when performing electrical maintenance. If
possible, leave the motorhome plugged into an
AC source with the chassis battery disconnect
switch on to help prevent the possibility of dead
batteries.
If an AC source is not available, and the
motorhome is going to be stored more than 48
hours, it is recommended to turn the chassis
battery disconnect switch off.
WARNING
When welding is involved for
motorhome repair or modification,
only qualified, experienced technicians
should weld on the chassis. Improper
welding procedures and materials
may weaken the assembly or result in
damage that is not obvious and may not
cause an immediate problem or failure.
Unauthorized modifications or repairs to
the chassis could result in a forfeiture of
warranty coverage.
DANGER
Due to the sensitive nature of the
electronics on the chassis, the following
precautions are required to protect
electrical components in the motorhome
chassis:
1. Disconnect the (+) positive and (-)
negative battery connection.
2. Cover electronic control components
and wiring to protect from hot
sparks.
3. Disconnect the terminal plugs from
the engine Electronic Control Unit,
located on the curbside of the engine
block.
4. Disconnect all the plugs from the
transmission Electronic Control Unit
located in roadside front distribution
panel.
5. DO NOT connect welding cables to
electronic control components.
6. Attach the welding ground cable no
more than two feet from the part to
be welded.
Battery - cHaSSIS
The chassis battery is designed to produce high
amperage necessary to start the engine. Maintain
the chassis battery through regular electrolyte
level inspections and hydrometer readings.
High electrolyte consumption, or inconsistent
hydrometer cell readings, may indicate a
charging system problem. Perform a charging
system and current draw check if the battery is
exhibiting abnormal hydrometer readings.
NOTE
Replacement
batteries should
have the same
cold cranking
amp (CCA)
rating.
fUSe & cIrcUItS
The motorhome relies on three electrical
panels to control chassis functions and some
house operated items.
The front electrical panel (also called the front
run box) is located in the outside roadside front
compartment and contains fuses, self resetting
manual reset supply circuit breakers, solenoid
and relays for many chassis and house related
functions. The front distribution box, located
under the front electrical panel, controls front
chassis functions only. A rear distribution box,
located in a curbside rear compartment, controls
rear chassis functions only.
