OK, so last time out last fall, I dragged my 7 wire cable (the one that connects the TV to the Trailer). I dragged the cable, and damaged some of the wires. I was ready to buy a new cable from eTrailer, but watching their how-to video, he cut the cable off and connected the new one using crimp-on butt fasteners. And I thought, I only really need to replace about 8" of cables, so, I cut the cable and reconnected all 7 wires using a crimp-on for each and matching it color for color.
So, after testing it, the night time lights work, but I still don't have turn signals. And haven't tested the brake lights.
But for the turn signals, what is the next likely thing to check?
