1. Do not simultaneously operate the generator
and a power vent, which could draw exhaust
gases into the vehicle.
2. Do not open windows or vents on the end or
side of the vehicle where exhaust pipe of the
generator is located.
3. Park the vehicle so that the wind will carry the
exhaust away from the vehicle. Also, note the
position of other vehicles to be sure their
exhaust will not enter your vehicle.
4. Do not operate the generator engine while
parked if vegetation, snow, buildings,
vehicles, or any other object can deflect the
exhaust under or into the vehicle.
NOTE: Check auxiliary generator oil level
frequently during periods of use.
Refer to the generator manufacturer’s
maintenance information in your InfoCase for
specific recommendations.
ELECTRICAL SYSTEM –
HOUSE 12-VOLT DC
The DC voltage system consists of the chassis
battery, the 12-volt house batteries, and the 12-
volt power converter.
Converter
See “Power Center.”
Chassis Battery
The chassis battery is used to operate the
engine starter and automotive accessories and
controls found on the instrument panel. The
slideout room systems and the electric step are
also connected to the chassis battery.
See your chassis manual for further
information on chassis batteries and chassis
electrical system.
House Batteries
House batteries are “deep-cycle” type
batteries specially designed for recreational
vehicle use. They will provide longer lasting
power than standard automotive starting batteries
and will withstand the frequent drain-and-
recharge cycles that occur under the demanding
conditions of a camping outing.
The house batteries supply power to 12-volt
equipment located in the living area of the
motorhome. This includes the following 12-volt
powered components (if equipped): interior 12-
volt lighting, range exhaust fan, propane furnace
fan, fresh water pump, systems monitor panel,
refrigerator, roof vent fans, and 120-volt
electrical generator starter.
House batteries are automatically charged by
the chassis alternator while the engine is running.
HOUSE/COACH BATTERY
DISCONNECT SWITCH
(COACH BATT)
The House/Coach Battery Disconnect switch
lets you disconnect the house batteries from the
12-volt system of your coach during storage
periods to avoid battery drain by electrical items
that are hooked directly to the house batteries,
such as clock displays and radio memories, etc.
Always leave this switch ON while using the
coach.
NOTE: Some electronic displays and memory
functions may need to be reset after
power has been reconnected.
See also “Battery Care” elsewhere in this
section.
