Now that I finally have the trailer registered I am towing around town to get used to it. On the first day, the brake controller (Tekonsha Prodigy) read .nc., which according to the manual means no trailer connection is seen by the controller. Next day there were no brakes
AND no turn signal/running lights
. I took the trailer to the shop that installed the new brakes
and repaired the trailer wiring. They found no shorts in the trailer wiring. Next took the truck to the UHaul
dealer that installed the brake controller. He found a 15amp fuse burnt out in the trailer turn slot under the hood. Now I have lights
but still no connection from the brake controller. He didn't have the fuse to replace the relay containing the electric brake fuse, so on to the Nissan dealer. They checked the elecric brake fuse (a 30amp) and it checked out fine. I hooked up again yesterday. I have lights
but when I applied brakes
while idling I got SH4 from the brake controller. That supposedly means the controller detects a brake wire short while idling. I drove the trailer a few miles and sometimes when I braked I got numbers (presumably showing proportional braking occurring), sometimes a nc code, sometimes SH4. It appears I have a short!
I described the problem to the UHaul
guy and I am taking it back this morning to have him check the wiring he installed. If that checks out OK, I will take it to Nissan and have them check the factory wiring (now I find out how good Nissan warranty is). If that checks out OK, I'm stumped! I would take it to a trailer place, but don't have time now before I head out next week. Camping world has a 3 week backlog in their service department! (I thought with the season and the economy, they would be hurting for work!)
Any suggestions as to possible causes?
If I can't get the wiring fixed, is it OK to drive to Arizona with the plug in (for lights) but no brake connection? I mean, the trailer stops OK without brakes, but will I be damaging or risking anything if I have no or intermittant connections?
