The main house battery disconnect switch turns the battery power supply
on or off. The domestic battery disconnect switch shuts off the 12 Volt DC
power to the following items: the inverter, the domestic fuse panel in the
bedroom, the domestic fuse panel in the front run box and the domestic
power supply in the rear run box(s). Turn the main battery disconnect switch
off when the motorhome is going to be stored or before performing electrical
maintenance on the motorhome. If possible, leave the motorhome plugged
into an AC source with the battery disconnect switch on. This will help pre-
vent the possibility of dead batteries. Use of the battery cut-off switch at the
entry door will not turn off all DC electrical items or other parasitic loads.
There are small parasitic loads that are present on the house battery. Some
are federal mandate items such as the LP-Gas detector. If an AC source is not
available and the motorhome is not going to be used, or is stored more than
48 hours, it is recommended to turn the battery disconnect switch off.
NOTE: The solar panels will charge the batteries with the dis-
connect switch off.
WARNING: When the frame or other welding is involved for
motorhome repair or modification, the following precautions are
required to protect electronic 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 wiring harness connectors at the transmission
electronic control unit. Open bed storage compartment, open
engine access door. The transmission ECU is located above the
transmission.
4. Do not connect welding cables to electronic control compo-
nents.
5. The welding ground cable should be attached no more than
two feet from the area to be welded.
