Tekonsha Prodigy P3 Brake Controller Shows Warning Output Shorted No Brakes with New Breakaway

Question

Question:

I have pro series breakaway kit installed on my trailer. It is showing a output short on my p3 tekonsha break controller. This only happens when the battery for the breakaway is installed when you take the battery out the warning goes away. It look like it was wired wrong so I followed the wire diagram for the breakaway and it is still causing the warning only when the battery for the breakaway is installed. Thanks

The "Warning Output Shorted No Brakes" error message on the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 per the manual can be caused by one of two 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 you have a short in the usually blue brake output wire or it is installed incorrectly. This can an issue on the vehicle/trailer or both. The only solution would be to recheck the wiring. It sounds like the issue is with the breakaway system. It could also be possible that the brake controller is incompatible with the breakaway system, especially if the brake output wire runs through a circuit board.

I would start by inspecting the connection on both your vehicle and trailer. This issue is often caused by corrosion on the 7-way connections. It probably wouldn't hurt to clean the connections one way or another. If this does not solve the…

If no trailer is connected and you test the brake pin on the 7-Way, there should be only be a tiny amount of voltage because that is how the controller senses if there is a trailer. But 3.5 volts sounds too high. If this is occurring without the…

Yes, it is indeed likely that your trailer breakaway batteries were depleted from the accidental tripping of the breakaway switch (but good for you for doing the yard work!). If your main trailer batteries have a charge line to feed the breakaway…

You can test the function of the slider's troublesome hydraulic actuator cylinder by swapping the wiring between the two cylinders. If the bad one now works (when connected to the wiring for the other) then you know the issue is not the cylinder,…

If you have a break away kit that does not include a charger, you can provide a charge to the battery using the 12 volt circuit or auxiliary circuit from the vehicle 7-Way trailer connector. However, using the 7-Way can overcharge a break away…

The brake controllers available now either are only on when they are activated, or a have a timed shut-off or idle state after a certain time period. Some of the older brake controllers never shut-off, but they did not drain battery power as the only…
