Battery Disconnect Switch
Battery disconnect switch on
The battery disconnect switch turns the coach battery power off
and on. When off, it prevents your coach batteries from being
drained while the Roadtrek is not in use. The lights, the water
pump, the fan, the refrigerator, even the igniters for the propane
cooktop need 12 volt power from the batteries. If something
electrical in your Roadtrek doesn't work, the first thing to check
is to make sure the battery disconnect switch is on.
The battery disconnect switch is on the bottom left corner of the
monitor panel. To its immediate right is a blue indicator light
which illuminates when the switch is on.
You will hear a "clunk" as the battery disconnect switch is
pressed - this is a big relay connecting the coach batteries to the
electrical loads.
If you hear a clunk-clunk, or nothing at all, it's possible that your
batteries are depleted to the point where they cannot drive the
relay. Take steps to charge your batteries, such as starting the
vehicle engine, and try again after building the batteries up to a
charge level where they will power the relay.
Inverter Switch with 1250 Watt Inverter
Just as the battery disconnect switch powers the lights, fan, and other 12 volt electrical loads, the inverter powers some of
the 120 volt alternating current loads. This is the regular electricity you have in your house.
The inverter takes 12 volt power from your coach batteries and changes it into 120 volt electricity. It powers the television
and home theatre system, plus some other outlet or outlets, depending on model. With this inverter, you can watch television
or play a DVD while you are camping, without the need to plug into shore power or run your generator.
The inverter is rated for 1250 watts maximum output, larger loads such as the air conditioner are too big to run on the power
produced by the inverter, and will not operate unless you plug in or start your generator. The inverter will shut off if you try to
draw too much power through it.
