I have a new 2020 Thor four winds 31W. We decided to get it ready for a trip next month so I purchased a brake controller from e-trailer, tekoshna p-3'
Well I plugged it in, brake controller flashed , unplugged it and now coach won't start. Checked every fuse I could find, disconnected battery so computer could drain, swapped relays around....Nothing seems to work, dealer is even puzzled. Hope to find someone that knows more or may its happen to????
