Trailer Wiring connection fubar
Have hooked up to three different trailers so the problem is with the truck.
Running lights and blinkers don't work (on trailer), but for some reason come on solid dim when Hazards are turned on. The trailer brakes hit hard with the blinking of the left turn signal, nothing with right signal...And trailer brakes hit hard as soon as you touch the brake pedal, no gradual braking....
I checked with a multimeter and I am getting intermittent voltage to the trailer brake connector on the 7 pin when the left blinker is on, and if you touch the brakes at all it goes straight to 12.XX volts as well. (KOEO) Which I would think indicates a short, yet there's no continuity between them with power off.
Anybody ever have similar problems?
Also I think this may be PART of the problem, it looks like a PO spliced both turn signal wires on the 4 pin into the running lights wire of the 7 pin...Is this factory, could one of y'all just take a look at yours?
