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 switch is located
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, and the Monaco 4 box. Both
are located in the rear curbside
compartment. Unscrew and lift
off the black box to access the
transmission electronic control
disconnect unit.
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.
