Maybe A simple Solution, But..
Not for me. The fuse in the truck that handles the trailer running lights keeps blowing. The turn signals and brake lights work just fine. When I replace the fuse the running lights work but then the next trip the fuse is blown again.
I always unplug the lights before backing down,
How do I find and solve the problem? It just occured to me that I'm probably using the wrong board but oh well.
forgot something...does your fuse blow immediately???

I your vehicle has one of those cable converters (plug in) that converts from 2 bulb, to 1 bulb signal and brake also go bad. If you are wired directly into vehicle wiring, check brown wire here too....
Do you have a volt-ohm meter?
