With no trailer attached remove the fuse and reconnect the terminals with a 12V bulb. Then when the light is on then move, tap etc various areas to help isolate the problem. It could be anything that doesn't work including wires. A wire tracer can help and a DC clampon ammeter can help to isolate which connection to the fuse is drawing excessive current.
