I have a short somewhere? How do I find it?
Just installed a new roof on my 1999 Coachmen Mirada. Problem is that I must have pinched a wire somewhere? 12v Ceiling lights in my RV don't work now. Checked the fuse, it was blown, replaced it and ...

OK Jim,
Yes you have a short circuit, they are much more difficult to locate than a break.
If putting the new roof on involved putting screws where none were before, that is where I would start. Get some way to put a light bulb where the blown fuse was. It will light. Get a friend to watch the light. You go up on the roof with a screwdriver and remove screws one at a time. If your watcher doesn't shout, go to the next one. When the light goes out (Hope-Hope), start putting all the loose screws back in. If the stays out, you only have to relocate one screw.
There are wire tracers that put a signal on a wire that you can trace with the receiver from the same set, but that won't get you much in this case. If could tell you the wire's path, but it would be very difficult to actually identify where the short circuit really is.
Good Luck
