    Sounds like ground. Clean the connection where the white wire goes on to the tongue for starters.
    If you have integrity, nothing else matters. If you don't have integrity,
    nothing else matters.​

    my old mans boat trailer was doing the same thing. his problem was a running light wire had rubbed the coating off and was grounding out on the trailer. try looking where the wires comes out of a hole and go to marker lights or brake lights.

    Its going to be a ground somewhere for sure. On mine, It was the one on my trucks end. I unscrew the ground screw, took a dremel tool with a small sanding wheel and it did the trick in 2 seconds.

    Let me recommend that when you hook up the boat to "TEST" the lights, hook it up fully, not just the light harness.

    In other words, put the trailer safety chain on the truck, and the hitch and everything, this further helps it ground. I found that out the hard way too, after resanding all grounds, and nothing changed, brakes still went out. Then I hooked up everything else and it was fine. (My boat was on gravel and the Truck on concrete)

    Not sure if that had anything to do with it either, but oh well. This has happened to me twice, once it was the ground, the other time, I just didnt hook everything else up.

    Hope it helps a little.
