Quoted from FrankyP:Bally nip it. first im new to ems and playing with this as a repair project. Everything was working fine dropped a bulb near scoring mech gently fished it out now suddenly ball counter is not advancing consistently sometimes goes to two player game lots of weird issues that i did not previously have. At end of ball randomly starts scoring continuously, what did I break?
Hard to say, you should probably just ship it to me . I’ve found slow motion videos to be helpful, maybe upload one to YouTube and link it.
Have you reviewed the schematic to see what steps up the player count and score reels? Here’s a link to the manual
