I have a Tekonsha Primus IQ brake controller connected to my one month old
Scamp. When I set the power level on the controller I can't get lower than a 6.0. or so. The trailer
brakes seem to work both manually from the controller and if I set the power value higher than 6, say 7.5 or so.
I called Tekonsha and they had me me look at the brake controller display both when it was hooked up to the trailer and when it was not. Tekonsha says that I have a "slight" short in my trailer-side brake circuitry that could be anywhere from the plug-in all the way back through the trailer. They also indicated, because of what the display was saying, that it wasn't on my tow-vehicle side or with the controller itself.
So I'm wondering where to look first for the short. While poking around and checking everything, I also notice that my back-up
lights on the trailer are not working. Could that be connected to the brake-wiring short issue?
All other exterior and interior trailer
lights work, including the brake
lights.
Thanks for any advice you might have.
