I have a boat trailer with surge actuated disk brakes. I have a 7-5 pin adapter. Last week the truck got backed in a little too far and I had water pouring out of my adapter. Ever since, I can' not back up the trailer - the brakes lock up on the trailer. I checked all of the fuses in the fuse panel - all of them. I replaced the 7-5 pin adapter. I checked all of the wiring on the trailer and am able to release the lock out mechanism by flipping my 5 pin plug upside down and turning on my lights. What am I missing? Is there a fuse somewhere that I am not finding?
