They were not getting to the battery. I noticed a low bat even though we were plugged into 110. Tried hooking up TV still no 12 volt. No matter what I tried could not get 12 v to the bat. Just out of nothing else to try removed the 12 volt panel with the fuses in it and low and behold one of the main leads was out just lying there and the other one was lose. All OK now.
We have been haveing strange problems for some time. This could have been it all along. So if you are haveing trouble with 12 volt check that out.
