I took a look in the owner's manual for the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 for you and the error message, "Warning! Output Shortage" can be caused by a few different things. I have listed these for you below:

1. Detects brake output wire shorted to ground. Short during idle condition.
2. Use of some test lights or non-Tekonsha testers can cause this problem.

Therefore, it sounds like there is a short in the usually blue brake output wire that runs from the braking assemblies to the brake controller through the trailer connectors. We do offer new wire part # 10-1-1 which is sold by the foot if you need to replace any sections.
