When a RV house battery is installed in
parallel circuitry with an 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 battery 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 battery 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
battery 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
house and chassis batteries. The generator
requires 12-volt power from the house battery
to start, and draws fuel from the chassis fuel
tank. If the fuel tank drops to or below 1/4 full,
the genset will automatically shut off to keep
the RV from being stranded. Be aware the
generator, when operating, gives off carbon
monoxide.
Always leave the ignition key in the "OFF"
position unless the engine is running.
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.
