I have one of the first model (I guess they called it the P1) and it is not applying any brakes. It shows voltage and looks to be working but I am not getting any results. Has anyone ever had the same issue? I checked the plug in my bed with a light tester and when I did the manual override it lit my tester. My poor little mind is spinning and not stopping as to what the problem might be. I don't want to invest in another controller if mine isn't bad. I noticed it not braking much with my other unit but I thought the brakes needed adjusted so when I replace the tires I adjusted them but it didnt change the outcome. Now my new 321 is doing the same
.. Any and all help/info would be greatly appreciated in advance..
