Two years ago I bought a used, 2001 Coleman Fleetwood Niagara folding camper. This spring I am having a problem with the 12V system.This camper has a kill switch under the folding galley. That switch, when open, disables the over head lighting and plugs.My 12 volt system that is below the galley - porch light, internally controlled marker light, etc. - is working fine.Nothing above the galley is working. I tried replacing the kill switch - no help.I checked, with an ohmmeter, all of the 12V fuses, no help.I checked the wires that come to the switch, and there is no voltage at that point.there are two 110V circuit breakers. One controls the converter. It is on, and the converter is getting power.What can I try next?

Broken ground wire, from the upper level to lower portion of RV? Should be in the same channel as the power wire. Maybe connection at top or bottom, as there would be movement when the roof is raised or lowered.Beverley and Ken

Might have a broken wire. Check where it flexes. PS: the break may be inside the wire and not readily visible.Check each end with your meter.

Check the connector and wiring that's by the rear/left roof support, it's tucked behind a flap with velcro in the tenting.

You seem to have done a good job of pin-pointing the problem. Somewhere between the kill switch and the converter a connection is lost. If the wires are color coded, as in the link below, you should be able to look at the wires on the kill switch and check that that same wire is hot at the converter. If not, it is likely the fuse, or just a connection on the hot side of the fuse - I say this as the other 12v outputs from the converter seem to be working OK. (outside light, water pump, etc.)Link to Wiring Diagram

The wires at one of my roof supports are always coming disconnected. They supply 12V to the roof lights and fan. I'll bet Beverley&Ken and Leaf-Peeper hit the nail on the head.

Apparently there is! Glad you got it figured out.

THIS WAS THE PROBLEM!!!

Thank you. I hadn't checked that spot. As soon as I climbed up I saw that the connector had come undone, plugged it back in, and... SUCCESS!!

Thank you to all who offered ideas and suggestions.

Happy Camping

Techwriter, I think the member status is more about how many posts/replies rather than calendar time. Just get into some lengthy discussions with RoyB, Oldman2, and Bondebond and you'll be a senior member in no time!

JLTN_James, Side-bar discussion. Your post shows you as as senior member while mine says new member, yet we both joined in 2009. Do you know what causes this to be displayed? I've checked the account settings and cannot find any way to change this.

Agree with the broken wire/broken connector. The power wires to the roof can easily get pinched and broken when the roof is lowered. If yours is like mine, the connector will be near a corner post and low near the box. Mine is at the left-rear post. I've had to repair it once already.
