Prodigty brake controler

I keep getting a short or over load signal.not all the time.I have soddered all the connections I can find.I wonder if I should add a ground for the hitch since it is mounted on a spray in liner.

Inspect the wiring leading to the brake magnets, looking for a nick in the insulation. Pay particular close attention to places where the wiring goes through a grommet or is strapped to the frame with cable ties.

Nicked insulation coupled with high humidity and/or rain could easily result in an intermittent shorting condition. When the Prodigy is indicating a short condition it's telling you the current is flowing but isn't seeing the resistance of the magnet coils.

ditto on what richard says. that is the biggest problem area.

I made a run this week end to Kentucky.Same thing it even showed a no connection a couple of times.It is weird I can hit the brakes and look down to an ol code hit the brakes again and it works fine.It showed a sh code comming into the yard I moved a couple of feet and it went back to normal.I set my inital power setting at 6.0 like the instructions say and run on boost 3 but she still does not want to slow down very quick if I get in a bind.

I can almost guarantee that what Richard said is correct. I have had the exact same problem and if you have brakes like mine (12x2) you will find that the wires inside the brake drums have metal clips holding them to the actuator arm, not to mention the wires wrapping around the arm, both of these places wear through the insulation and cause the problem you are seeing. Also I have found magnets off the actuator arms and laying in the drum both times I have taken the drums off. I'd almost bet that is where you'll find your problem.
