Trailer Running Lights Wont Work. The running lights worked on all trailers previous to the problem beginning. The Lights on the inside, and outside lights wont work, however the tail lights work and so do the flashers and turn signals.

Just run a Multi-meter on the connections mate.that will tell ya if your getting power to the plug.
