Hey all, thanks for your help. I checked all fuses but none were blown. Then I remembered that when I installed trailer harness years ago there was a fuseable link. I had to take the spare out to get to it but it was fine as well.

Long story short, I took the boat out to gas it and it was still acting up. By putting a nickel in trailer brake slot it deactivates the trailer brakes so that is what I did. Then when I took the boat out for the season it started working fine. I suspect it was a ground issue so might not know where the ground fault might be. Thanks for all of your help.
