RV Repair: slide electrical fault, zero volts, circuit breakers

Question
I have an Rvision Condor 2001 and the room slide suddenly stopped working.
I downloaded fault finding sheets from Powergear.
The first thing it said was to disconnect the wiring harness from the relay board and check the voltage between the red and black wires.
I did that and found zero volts.  It then said to check voltage at the battery – that was OK.  Then said to check for blown in line -fuse, bad connections or break in the wire.

I can’t see any of these things near the battery.  It would be useful to have a wiring diagram of the vehicle to try to trace the fault, but these seem to be hard to come by.
All the wiring is encased in conduit so it’s hard to trace.

Any suggestions would be much appreciated.  -  Geoff


Answer
Geoff, If you look near the batteries and to where they hook up you should see what appears to be a terminal block that has wires on both sides. These are circuit breakers and you might want to check both sides of each to be sure voltage is making it through. I would bet that one of them has been tripped. Some of them are even resettable. They will be at least 30 amp and usually no more than 50. Thanks, Bill
