This section contains knowledge and instruction regarding various components
of the Chassis Electrical System. Following the guidelines and procedures will
assist in understanding and operating the motorhome. Individual component
instructions for chassis electrical items and their respective operators manual are
included in the Owner's Information File box.
The 12 Volt DC panel that services a majority of the chassis system functions
is located outside by the roadside front wheel. The engine battery supplies 12 Volt
DC power to the front distribution panel. This panel contains mostly engine system
fuses and wiring such as headlights, taillights, dashboard functions, gauges, etc.
WARNING: When frame or other 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.
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, and any electronic control ground wires
connected to the frame or chassis.
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 passenger side
of the engine block.
4. Disconnect all the plugs from the Allison Electronic
Control Module located in the Electrical Bay at the
driver's side front of the vehicle.
5. Disconnect the 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.
