So it says it’s working, the “gain” line moves when the brakes are applied or the lever is moved but not doing anything to the trailer brakes.
Can only get about 6 volts to the plug with brakes applied.
Doesn’t seem like enough voltage.
Tried a different truck and the trailer stops fine.
Anyone know if that is a plug in unit. I have 2 17s, one is a 1/2 ton and is never going to pull trailer.
Is it possible to switch the controller?
