Front Light Blowing Fuse

BradS7535 · 05-10-2018, 07:30 PM

So on our last trip I turned the switch inside the vent for the two front lights, then manually turned on the front driver's side light and blew the fuse for the front shell. Had some spares and replaced it and turned on the passenger front light no problem. Tried the driver front again and POP! I replaced all my interior lights with LED bulbs and when I did the swap everything was working fine. What could have happened that is now causing that one light to blow the fuse?

I'll have some time this weekend hopefully to open it up and troubleshoot, but what are some steps I should take? I was going to first try another bulb, maybe something inside the LED bulb shorted?

Our front lights are also not working on our Trailmanor. They worked when we picked it up on Friday from the original owner, but now do not. The 15amp fuse sparks when trying to put in a new one. We assume a wire is crossed somewhere, but have not been able to find it in any obvious locations. Any advice would be appreciated.

Take the bulb out and see if it still sparks when you put in a fresh fuse (sorry about killing another fuse). If it no longer sparks, just replace the bulb. Sometimes they short when they fail.

We took out the bulbs in the four ceiling lights and the reading light on the front half. We were able to replace the fuse without sparks this time. However the ceiling lights still do not turn on after replacing the bulbs. The exterior light next to the door on the front half does work though. The interesting thing about the exterior light is that it is not connected to the white wire, it is just grounded to the frame of the Trailmanor. So the problem seems like it is not in the black wire running to the front half - seems like it is in the black wire in the roof or the white wire. Has anyone else dealt with a problem like this? Any suggestions would be appreciated.

Pull the switch for the porch lights and look at the wiring there. On my 3326 one of the screws got the oorcu light was so long that it was rubbing through the insulation and causing a short to ground.

Pulled the switch for the porch light, everything looks ok.

It sound like a direct short somewhere in the front light circuit. The Blue Book will show you where the wires are routed, but it is almost certainly a short in one of the fixtures. There is no way easy to check them, other than opening each fixture and visually looking for a short.

There are also two lights under the front cabinet, and sometimes a clock, and does the fan work?

We have a 2001 3023 model. It has 2 ceiling vents, each containing two separate lights and one ceiling fan. It also has one reading light by the front bed ( the 2nd reading light has been capped off), a clock and 2 speakers for the radio. The speakers and clock work, but the ceiling lights and fan do not work. These lights and fan all worked when we picked up the TM from the previous owner on Friday. We assume some wire came loose driving back to our home, but we have yet to find an obvious disconnect or exposed wire.

We will try looking at each individual ceiling light in the morning as was suggested. Any suggestions or advice is always appreciated.

i also had an issue with some of the wiring in the ceiling for the lights coming loose. They use scotch-locks or sometimes just twisted and taped wires at their splices. Some started coming apart.
