Hello everyone. I have a Top Card pin. During play it skips ahead the score and I could hear relays chattering. I found that the EOS on the ones was snapped off. I've replaced that. Then the problem got progressively worse. I've cleaned all contacts in the backboard, target contacts, all male and female jones plugs. Checked rollover and ball lane switches. As I clean things, the problem gets worse. It starts up normal, resets to 0 then when I advance the ball, the score rattles up to around 8000 and all the score reel relays lock as well as the rollover relays. I will not have my schematic until next week. Any input would be appreciated. Thanks
