Just bought my first AS, it's a 1970 27' in great shape.
I have a Prodigy electric brake controller in my Tow vehicle.
I have used this unit on two previous trailers (non Air Stream) and it works fine, just plug and go.
I hooked my AS up for the trip home and immediately the back up lights came on, without the tow vehicle even starting, just plugging it in, they stayed on the trip home.
As soon as I got on the road I also noticed that the trailer brakes were not working. I stopped at the first rest stop and checked all of the wires in the mail plug from the AS, they were all connected properly to the corresponding color tabs.
I also noticed, that I can not back the trailer up (as the brakes lock up), unless I disconnect the plug, then it works fine, this must be a hill hold device with AS?
Sooo, the brakes seem to be working, but it must be wired improperly from the AS. Any suggestions???
