ATTERIES
Each OEM chassis is built with batteries to
provide energy to start the engine and
operate devices supplied with the chassis.
The OEM chassis battery is furnished and
warranted by the chassis manufacturer (as
applicable).

OLENOID
When house batteries are installed in parallel
circuitry with the OEM chassis battery, the
charge level in both connected batteries will
naturally equalize. An isolator solenoid is
incorporated to break the connection between
the house batteries and the OEM chassis
battery when the ignition key is in the OFF
position.
Breaking this connection prevents discharge
of the OEM chassis battery (used to start the
engine) when using the 12-volt devices in the
house section of your RV. When the engine is
running the isolator solenoid engages
allowing the house batteries to be charged by
the vehicle alternator.

The 12-volt fuse panel is labeled to indicate
the fuse sizes, positions and components
powered. At the beginning of camping
season, inspect all the 12-volt fuses and
replace as needed.
Replacing a fuse
Before replacing a fuse, always turn OFF the
electrical component(s) protected by it.
1. Disconnect the power cord.
2. If so equipped, disconnect the house
batteries negative cable at the battery.
3. Remove the fuse panel cover to check
fuses.
4. Pull the fuse straight out of the fuse block.
If the fuse is not blown, something else
must be causing the problem. Please
contact your dealer for further assistance.
5. Insert a new fuse of the same specified
voltage, amperage rating and type in the
original location.
Never use a higher
rated replacement fuse.
The fuse panel label should be kept
permanently affixed to your RV. The fuses will
not offer complete protection of the RV
electrical system in the event of a power
surge or spike.

The factory-installed generator (also called a
genset) will produce 120-volt AC power for
use when camping in areas where shore
power is unavailable. 120-volt power from the
generator is output to the AC distribution
center by way of a factory-installed automatic
transfer switch. In the default mode, the
automatic transfer switch connects the
generator to the AC distribution center when
the generator is operating and shore power is
disconnected.
When the generator is operating it will power
the converter, which in turn will charge the
Replacement fuses must be of the same
voltage, amperage rating and type. Never
use a higher rated replacement fuse; doing
so may cause a fire by overheating the RV
wiring.
Always wear eye protection when
working with batteries.
Keep sparks,
cigarettes and flames away from the
battery because the battery may explode.
Do not use a booster battery or any other
power source that has an output that
exceeds 12-volt. Use adequate ventilation
when charging or using the battery in an
enclosed space.
Always leave the ignition key in the "OFF"
position unless the engine is running.
