I replaced the pin, rerouted the cable with zip ties but, still had "no connection" on the brake controller in the cab. So Vonnie watched the controller while I crawled all around wiggling wires and cables. It appeared that the problem was at the plug where it attaches to the truck. I filed all of the contacts and a "c" (connected) stayed lit on the controller. It appeared the problem ws solved. I wanted to have a guy in the Camping World shop double check it but they said it probably wouldn't happen that day. So we took it for a test drive and everything seemed to work. So off we went down the road. All in all it was a 2 hour delay but cost me nothing in cash so all is well.
A side note....about an hour down the highway, I'm doing about 60 mph. I had an idiot flip a u-turn from the north bound to the south bound lane on the 101 and pull right in front of me. I could not avoid him because I had a vehicle next to me so I had to get on the brakes (and the horn) real, real hard. If we had not seen and taken care of the trailer brakes, like we did, I would have never been able to slow down that fast and the outcome would have been very grim, indeed, for all parties involved. I have installed an exhaust brake in my truck last month as well and we used every bit of that. I think someone was really looking out for us on this particular incident. By the way, the exhaust brake is by far the best improvement I've made to our tow vehicle and I can't say enough good about it.
Got packed up and headed toward Pismo Beach in the morning. After driving several miles down the 101 I noticed my trailer brake controller was flashing "nc". This means not connected / no trailer brakes! Being that I'm pulling a 14000 lb unit behind me with no means of stopping it in any kind of safe distance, I would obviously have to pull off for repairs. We saw a Camping World a ways back so we headed back and pulled in there. This is when the whole trailer locked up and I was stuck in the middle of the parking lot. I was thinking I burned up a wheel bearing or something happened to one of the axles. Vonnie and I got out and were looking all over trying to figure out what the hell was going on. So I went from having no brakes to having nothing but brake. Turns out the run-away trailer safety pin pulled out at the pin box. (this is the pin that is pulled when a trailer accidentally detaches from the tow vehicle at speed and will lock up the brakes, ultimately stopping the trailer. ) I had the cable that holds it wrap itself around the sliding hitch. Freak accident.
