Question:

I have a act 3 controller and have replaced the 10gauge wire from trailer to plug and am showing an output of 1.6v, with truck off and no application of brakes, Im am thinking the controller has a fault?

If you can verify that the red wire of the controller does not have any voltage on it and the controller is still putting out 1.6 volts with the manual lever not slid at all then yes it is bad and needs to be replaced. You can try sliding the override lever a few times to see if that will clear out any bad contacts inside of it. Most likely it is time to replace the controller though.

For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. 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.
