Inverter/Charger:
The Inverter/Charger provides silent AC power when shore power is unavailable, and the generator is
not selected as a secondary power source. This device has limited AC power output, measured in
watts, and operates only selected appliances and outlets. The Inverter/Charger is an auxiliary 120 Volt
AC power source that inverts 12 Volt DC house battery power to 120 Volts AC. The Inverter/Charger
also converts 120 Volts AC power, supplied from either shore power or the generator, to 12 Volts DC
power, to recharge the batteries. When dry camping, the Inverter/Charger may be used to supply power
to selected outlets.
BATTERY DISCONNECT - HOUSE
The main house battery disconnect switch turns the house battery power supply on or
off by disconnecting 12 Volt DC power to the following items: inverter, domestic fuse
panel in the bedroom, domestic fuse panel in the front run box and domestic power sup-
ply in the rear run box(s). Turn the house battery disconnect switch off when the
motorhome is going to be stored, or before performing electrical maintenance. If possible,
leave the motorhome plugged into an AC source with the battery disconnect switch on to
help prevent the possibility of dead batteries. Use of this battery cut-off switch will not
turn off all DC electrical items or other parasitic loads present on the house battery.
Some are federal mandate items such as the LP-Gas detector. If an AC power source is
not available, and the motorhome is going to be stored for more than 48 hours, it is rec-
ommended to turn the house battery disconnect switch off.

ARNING:
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.
