Battery disconnect switch
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, etc. - all 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 to show you that your
batteries are supplying power to the coach.
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.
