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 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 precau-
tions 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 passenger side of the engine block.
4. Disconnect all the plugs from the transmission Electronic Control Unit, located
in the storage bay between the frame rails.
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.
BATTERY - CHASSIS
The chassis battery is a crank type battery 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 charg-
ing 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.
Battery with cover removed. Cut plastic to
remove cover.
