Hi and Merry Christmas everyone! I have a Gottlieb Top Score. I'm just really not sure where to start or look for a solution as I am pretty new to the EM world. Anyways, my Top Score will not score any points from the playfield, no matter what the ball hits or comes in contact with. No chimes either. But it will add bonus balls in the BG and it will score those bonus balls after the ball has drained. I have replaced a few broken switches on the score reels that I've located. Logically to me, it seems like there should be one switch or unit that is prohibiting PF scoring? Any help would be greatly appreciated.
Thanks,
Scott

Thanks folks! Off to try a few things..

Hi. Flippers work fine.
Something new to add, of course. Player 2 does score except for the occasional reel sticking. Player one does not score.
Rolf, can I ask a question about schematic reading. I'm getting better but still a little confused. So on the right side of your pix, following your red line, it passes over several dots. Does that mean the current can travel left at each of these dots? Like a sort of intersection? Or will it go that way relevant to what is supposed to happen next? Flowing where switches are open or closed. Basically, what are/do these dots represent?
Thanks for any clarification on this matter.

Thanks Rolf. And yes, I do have the schematics for this Top Score. It's a learning experience for me at this point. I have some things to try & hopefully some stuff will connect in my brain & I'll get one of my favorite em machines cooking.
Happy New Year!
