Hi have a Stern “pinball” em that is technically a Chicago coin. There is a stepper unit see (pictures) that the board that the swipes run along is completely burned up. I guess I could try to repair with conductive epoxy but hoping someone has one of those hiding in their parts bin. Also need a schematic having trouble locating that as well. Thanks for your help looking forward to getting this machine up and running once again.
Regards
Al
