Looking for part for Williams scoremotor, it is a long dwell cam for the scoremotor.
Used for resetting the drop targets.

Thanks, already found one from a local repairman.
Think it was not overfused but someone used contact cleaner and tried it immediately.
So the unit "fired up", this could not happen with a short, the plastic on the contact side was still in good shape.
Machine is working for 99% now, only thing is the targets resetting and not kicking the ball out of the center kickouthole when it reaches 10,000 points.
