Well I found one problem I must have over-looked. Usually I catch things like this before a power up. The diode seems to have been damaged. Not sure if it was by a person or some other issue. Either way, I will replace. Another issue I noticed when I first had it apart was that someone has played with the yoke. I did find some damage to the analog where the yoke plugs in. I bet someone tried to fix things but missed the obvious burn marks. Although I am not sure how adjusting centering would have helped.
