I know what the dots mean and i know that is normal, but I have a manual and the way I read it when there is no trailer the NC should only light if I slide the manual brake control. Mine was showing NC all the time after I disconnected my trailer. And it did not turn off after more than 30min of sitting.
I pulled the fuse and put it back in and for now it is working right. I will see tomorrow after towing the trailer home if I start having the constant NC lit again.
I was hoping someone with this controller could tell me how their units acts.
I agree with what you are saying here. Mine works that way: if unplugged from the trailer, all I get is the two dots, and I do not get the NC ( not connected ) unless I pull the manual lever.
Mine goes off after shutting the truck off after about ten minutes. Unless I touch the brake pedal, as that is what wakes it up again.
Call teckonsha and ask them about it.
Your output voltage sounds about typical for normal braking. If you were to go into a full on panic stop, you will see higher voltages going to the trailer.
