Glacier Bay Fiver - Electrical Short - Need Help

The other night a breaker popped. I reset it and a 1 minute later it popped again. We began unplugging things and eventually everything on that living room circuit was unplugged and the breaker would still pop, only now after only 10 or 15 seconds. The local service guy, who is very good at this sort of thing, said there is a short somewhere but he could not find anything obvious. Two of the outlets are in slide-outs but the curly wires did not look chewed at all. He will be back when he can dedicate more time to this mystery.

My question is, does anyone know where a wiring diagram might be obtained? As far as I know, Glacier Bay trailers are still not being produced.
  • I continue to learn from my mistakes.

    I talk to the tech this morning on the phone. He explained to me that those two curly pairs of wires going to each of the slide-outs are made up of one 110 volt line and one 12 volt line. They do not daisy chain the circuits like in a house. It is not 110 volts out and 110 volts back in as I wrongly assumed.

    Armed with my new found knowledge, and knowing that disconnecting the juice to the street side slide-out results in the breaker not popping, I concluded that I would leave the street side slide-out circuit open, close the breaker, and check the other five outlets. Sure enough, the other five outlets are working again.

    Now that I know about the basic way the circuits run, I know how it was that I fried the 12 volt breaker. The factory made a connection of an orange wire to a black wire, which was okay because both were at 12 volts. But when I connected that orange wire to a black 110 volt wire the sparks flew.

    There is a problem with monkey see, monkey do. I guess the breaker will have to be replaced. Much to my surprise, none of the light bulbs blew.

    Until my service guy can come back out, we will be dining by candlelight. All of the other lights in the trailer work fine. There just isn't any light over the kitchen table.
  • I found the junction boxes for both of the rear slide-outs. Disconnected the juice to the last outlet and the ceiling fan that is connected in the junction box on the passenger side. I still had a short.

    Disconnected the juice for the other slide, which also includes all 4 of the outlets in the television/surround sound cabinets, and the short disappeared.

    NEXT - Reconnected just the wires to the slide-out (which only has one outlet) and the short reappeared. So the problem is in the street side slide-out.

    I should have stopped with this amount of success and turned it over to the tech. But no, I had to try and bypass the slide-out with the short circuit so everything else would work again until it was totally fixed.

    But I had one white wire, and then another white wire with an orange stripe. So I put white to white, and white/orange to black.

    Well that shot sparks out of the 12 volt panel and now my 12 volts lights in that one slide-out do not work. I assume I fried the protective relay.

    Time to hit the shower and wait for my tech to come back.
  • On a short circuit you can remove the circuit from the breaker and wire a DC turn signal flasher to it. Then you can travel down the circuit with a compass and identify the spot where the short is located.

  • Problem number one. The outlets do not seem to have any "extra" wire. So you cannot pull them out of the wall. But I'll try again on some different ones.

    The tech used a continuity tester downstream of the breaker and after 10 or 15 seconds the tester beeped indicating it saw a short. That is the same kind of timing for when the breaker pops. Switching the breakers might be something to try even though the breaker seems to be working they way it should.

    I might add the trailer was stored in Florida for the summer and there are countless squirrels in Rock Crusher Canyon RV Park.

    I ran a heavy duty extension cord to the unused 20 amp outlet on the pedestal, and brought it in the window. So we are fully functional.

    But this has to be fixed somewhere along the line. My service guy will be back next week when he can schedule more time for me. He is one busy guy with all of us snowbirds coming to town. In the meantime I will do some snooping around of my own.
  • did the service guy replace the breaker? If not, an easy test would be to take another breaker from your breaker panel with the same rating and exchange it for the breaker that's tripping. If the replacement trips you know you've got an electrical issue, if not, then you have a bad breaker that you need to replace.
    If you're comfortable working with electrical it's something you could do yourself.
  • This is going to be time consuming but you need to find the shorted outlet/wires.

    Open the AC circuit breaker that is causing the trip.
    Check the wiring at the CB.....good tight connections.
    Then go to first outlet in the string and pull it out of wall. Check wires on that outlet.....the outlets in RVs are poor design. They use clips that the wire press into. The clips can get loose making poor connections or wires can come out of clips.
    First outlet checks good...then the next one and next one and next one until you find the loose/bad connection.

    Pain in the rear but it's obvious that it's a wiring/outlet problem (trips without anything plugged in)

    Wiring diagrams........HA
    The installers just run wires from AC panel to the various circuits where they can.
    So you have to identify which outlets are not working and then go from there.

    Good luck!
  • I would start by looking at each outlet to verify the wires were tight. If that is not it, I would next replace the wires under the slide out. It is quite possible there is a wire broken inside and not visible.
