Electrical mystery

Today I had a mechanic come to me to do some wheel bearing work. Put the slides in and all was well. When he finished, I went to put one of the slides out and it's no go. Fortunately I had a mechanic handy, and he checked the switch and discovered there is no power to the switch. Using a jumper from another switch that had power, we were able to move the slide. So, obviously no power from fuse panel to switch. Fuses all good. Wire from switch disappears into the wall and somehow makes its way to the fuse panel along with all the other wires in the switch panel. No signs of mice, or any particular reason to think a screw pierced the wire somewhere along the line, but I guess it is possible.
Trying to trace the wire would probably require removing cabinets, cutting holes, etc. to try and find the problem.

The mechanic pigtailed power to the switch so all is working. Guess I will never know unless I start tearing things apart, unless someone has any ideas....!
  • Roy was correct.

    Found 2 30 amp fuses coming off the batteries. One of them was blown. Guessing one fuse for each of the larger slides, and the smaller fuse in the breaker box probably goes to the small slide.

    Thank you again!
  • Slides usually have an auto resetting breaker someplace. It has probably failed or has loose/corroded connections.
  • Roy,
    There is nothing specifically listed in the fuse panel for the slideouts, although there is 1 12v fuse that is labeled "S/O Hitch". We assumed (right or wrong) that it is for the Slide Outs and the tongue jack. I'll take a look around the wiring coming off the batteries. Thanks.

    I have a small fuse block mounted on the wall where the battery is located for my slide-out on my 5th wheel. Fuses are not in the 12VDC Distribution panel...

    The newer trailers most likely will have reset type circuit breakers perhaps...

    Check in the near vicinity of your batteries.
