Ok, im a trouble shootinfg rookie here with old eyes and im going to revive this old post that i think i have tried everything already stated(i think). Plugs on the rectifier board were already replaced. All fuses check out good. I Just got the machine and everything worked until i replaced some bulbs. Now the two top hidden gi's are out, right slig gi and the kicker. Im sure these must be on one chain but they are very far apart. Any help, please
