tested battery it is dead ,but I thought the battery would be out of equation when plugged into park power I have buddies that dont have there batteries in camper and they don't have issues.is there a fuse possibly up near battery or a reset button near frame up front?
It is out of the equation, but if you want to prove it, disconnect it and you should have all of the 12V stuff working. The battery supplies nothing on the modern converters when plugged into shore power. If you don't have 12V with the battery disconnected, the converter is bad. This is not rocket science.
