Short in Brakes
I have a Primus IQ brake control unit. When I plug it in not connected to the trailer it says NC for no connection. When I connect the TM to the TV it says SH for a short in the system. I have disconnected the wires at the wheels. I have checked the wiring from the harness to the where the wires split to the two wheels. That wiring is good. (I connected the the positive wire at the split to another wire which I ran back to the trailer plug and tested continuity. There was no short in this wire. Same for negative). I then reconnected the wires to the drums: Short in System. Any suggestions?
