Hey , I know I started this post, but I given up on the tailgater or maybe coach wiring. I took the coach to CW were I got tail gater & motor home . They seem to know nothing about get it working.
I just am not leaving the motor home there for a week or so for them to play with , when I can be on the road enjoying the time I have. They seem to be too busy or they just don't know what to do . Tried two different recivers still no sound. Just venting and wanted to let you know what has happened. The tech told me that the tail gater had to small of a dish to get good reception. I think he just doesn't know. Thanks for all the suggestions of help.
