I pulled boat out of garage to park on street before heading to the lake. I always turn my blinking hazard lights on and noticed that my side clearance lights and my reverse LED white lights (that came with the trailer) where all blinking as well. The trailer back left was NOT blinking but the back right was blinking as it should. I also noticed the LED white reverse lights were on even when not in reverse and no hazards turned on.
I turn my trailer tongue to store my boat in the garage. When I stored boat Sunday, I checked this plug. Everything seems tight. No nicked wires of any sort. I have my hydraulic lines and wires spaced so there is not tightness or hard pulls of any kind when turning tongue.
Where is a good place to start for a guy with little understanding of this? Truck or trailer?
