Why Is The Voltage Not Increasing On A Tekonsha P3 When The Brakes Are Pressed?
Question:
Should the voltage number adjust as I press the breaks on the car? It will only move from zero when I use the manual override

Expert Reply:
As the Tekonsha Prodigy P3 Brake Controller # 90195 is a proportional controller, the voltage output will not increase unless the vehicle is also decelerating. This is due to there being an accelerometer inside the controller that, when the brakes are pressed, will sense how hard the vehicle is braking and apply the trailer brakes equally/proportionally. When the manual override is pressed, it will bypass the accelerometer and cause the brakes to engage.
With that being said, if this is happening when the vehicle is in motion, you will need to double check the red wire going onto the controller. This is the wire that is used to carry the signal when the brake is pressed up to the controller. If there is no power going through it when the brake is pressed, you will need to check to make sure you tapped into the correct wire if you had to hardwire the controller to your vehicle, or if you had a vehicle that had a port to plug into, you may need to see an auto shop for diagnosing it. Definitely check to make sure it is fully seated in the plug before doing this though.
