Brake Controller Replacement Recommendation for Controller Losing Voltage

Question:

HI, what is the typical voltage output testing directly at the brake controller. Im getting 12.7V input and max 11.3V output at full gain. This a older reese brake controller. At truck Im getting 10V and trailer near axle 8.9V.

There really shouldn't be any voltage loss between the input side of the controller and the output. Sounds like your is slowly failing and will eventually stop working. It would be time for a new controller sooner than later.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.
