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 switch
controls DC power to the
roadside 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 the
circuits will remain active with the disconnect
switch off.
Turn the chassis battery disconnect switch
off when the motorhome is going to be stored
or when performing electrical maintenance. If
possible during storage, 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 firewall.
4. Disconnect all the plugs from the
Transmission Control Module
located in the roadside front
electrical bay.
5. Disconnect wiring from the
alternator
6. Do Not connect welding cables to
electronic control components.
7. 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
batteries are exhibiting abnormal hydrometer
readings.
NOTE:
Replacement
batteries should
have the same
cold cranking
amp (CCA)
rating.
fUSeS & cIrcUItS
The roadside
electrical bay (also
called the front run
box) contains fuses,
self-resetting and manual reset circuit breakers,
solenoids and relays for many chassis and
house related functions. The front distribution
panel controls chassis and house functions.
Chassis fuse box 1 and 2 control chassis
functions only.
Battery with cover removed.
Cut plastic to remove cover.
