Troubleshooting a short

The test lamp is the only way to go, but you also have the problem of making the dealer respond to a warranty issue that should not be ignored.
It is very easy for the assembler to trap a wire that will get crushed and short to the frame later. These can be very difficult to locate. But, if you are going to try, get the test light lit where it should be a fuse and start taking things apart. The easiest ever was a shorted bulb. So, turn each light switch. if you are not sure which is on or off, remove and disconnect the fixture. Do not reconnect it until you are done. If you get them all apart (remember those lights in hidden places - too) and the test light is still on, then you have a wire damage issue.
Before the depression, I did a lot of this sort of work both for boats and RVs. Things like this can be a real bear to locate. I have found that it worked best to try to start with the light that is closest to power first. They are typically "daisy chained". So, if you break the circuit there and loose the short, you can put it back together and keep going.
Good Luck
