I just got a new Prodigy, but I think mine might be defective. It shows n. c. (not connected) even with the trailer hooked up. I know I got the wiring right because it works with the old controller. It also doesn't show the indicator that is supposed to tell you when the controller is set too high or low of an angle. It am thinking of sending it back for a new one. Do any of you guys think that I got a defective controller?
