It wasn't until it showed reversed polarity with the Generator running that I started to suspect a ground issue. My loose ground was at the ground bus bar right behind the meter panel above the door. It was actually the ground for the reversed polarity light causing the problem. There is another ground bus bar behind the TV above the drivers position.
Hope this helps.
