I have a 2007 Fourwinds 33K (C5500). The orange marker lights on top in front and the side have no power. The fuses are all good in engine bay and behind dash. The mirrior markers,Hood turn singles, and trailer lights work. I did get mice this year but if they chewed a wire I would blow a fuse. I am looking for other ideas of things to check or does anyone know exactly where Fourwinds ran the wires and tied in.
Thanks

If they chewed wire it does not follow you would blow fuse.
Work backward from the lamps.. with a Volt meter until you find the problem.

I traced the wire all the way across the undercarage. Into the engine bay. through the fire wall. the wire was good but no power. I can't find were it ties into the truck with out tearing the cab apart. Fourwinds never answered the phone. I will go without lights before I rip into the dash.

Power box in Front is where they normally tap off for the lights.. check fuse box there.

I had the same problem with my marker lights on my Jayco Seneca. What i found was a blown bulb in one of the marker lights above the cab.What happened to mine was caulk failed and allowed water to get inside the light and blew the bulb. I replaced the bulb, re caulked the light and no more problems. Hope this helps--this is a common cause.

I had the same problem with my marker lights on my Jayco Seneca. I found a blown bulb in one of the three marker lights on the front. What happened was the caulk failed and allowed rain water to seep in and blew the bulb. replaced the bulb re-caulked the light. That was two years ago and still working. This is a common problem. Hope this helps.

You might check to see if GM/Chevie publishes a "body builder's book" which contains info (diagrams, connector data, etc.) on how RV builders are to interface to the chassis electrical system. Ford publishes one for each model year and I have found it a big help in isolating problems such as yours.

What were you using as a ground to check for voltage at the socket? If it was the socket's ground, you may have ground issues instead of + issues.

I checked all the bulbs and they are good. I checked the ground to the frame of the truck. That was good.
I will wait until I get home then check it all again. If I can't find it then I will have to take it in. I will post what I find when it is all said and done.
Thanks for the ideas.
