I had a burnt CN1 on my JP power supply, and had a hack to make a connection from the back of the board. This was what I thought was causing resets. I used a replacement kit (from action pinball) that cost $10, and the game runs great now. So I agree, worth just trying to replace the burnt connector, but if your a novice to board work (like I am) be careful when replacing the male part on the board. I tried this on my TAF, and ripped the through holes. On JP, I used chipquick to keep the solder liquid and that worked for me.
