Trailer interior dome lights not working
Wondering if anyone else has seen this. We have a 2004 Charmac 2 horse trailer and the 3 interior dome lights (1 in tack room and 2 in horse area) no longer work (all the outside lights work fine). Have checked the voltage on the 7 pin connector and they are OK. Thanks for any feedback to help me in getting this fixed.

Check underneath the trailer for a wire that was pulled taught across a sharp edge of the frame or in some other way got pinched off or frayed. Also check for an in-line fuse that would be blown. Another thing to check is the ground on the dome lights. The marker lights get their ground directly from the sheet metal or frame of the trailer, so look to see if the dome lights are the same. They could even be wired christmas tree style with a common ground for all three lights. Also check that the ground is good at the 7-pin plug.

Thanks for welcome. You can usually find me hangin out in the Super Duty/Heavy Duty forum. Always finding good info there for my '01 F250 
Had a quick question - what in-line fuse are you referring to? Truck or trailer? If trailer, where would I start looking for it?

Trailer. If the pigtail goes under the tongue, look there. Also the interior lights are probably not on the same circuit as the marker lights. They should get power from the 12V or auxillary pin.
