One possible option. (If others don't chime in with an alternative.) If you have a diagnostic key (After first writing down the options / settings as a precaution) Would you be able to clear the safestore and the cabinet memory and set it up again?

Hello all,

Not sure if this is allowed or if this is thread to share this, but thought some might appreciate it. I love Pinball have an S  Pinball machine. I have been filming when we get the 100 credits in the bottom in the hopes of capturing the top bonus with all balls in the bottom since (as far as I’m aware), there aren’t any videos of this publicly/readily available for the older cabinet Pinball. Never really thought we would hit anytime soon, but got super lucky and got the top bonus! I posted the video on YouTube for documentation purposes, so I’m providing the link if anyone is interested in checking it out. It was a pretty cool animation when it hit! Thanks to this group as well to help me get the machine up and running smoothly!

Thank you.  I can contact member lookes.  He just helped me with a different MPU from a different game.  Are there schematics available for the mother board so I can ohm it out?  Thanks!

Thanks for the feedback.   It is 0 ohms with the plunger pulled out.  I guess the next step is to try another MPU board or mother board.  Does anyone on here test MPU boards?

Thank you for the diagram.  I have traced it out and I believe I have all the connections from the mother board to the switches correct.  Further, I have tested each switch with my ohm meter and they seem to be working correctly.  Unfortunately, I am thinking the problem is in the motherboard or the main MPU board now.   I am struggling a bit here because I do not have another main MPU board or motherboard to try out.  Any suggestions?  Maybe I need to send either of them out for testing?

Also, I see that only 3 of the 5 yellowish LEDs are illuminated on the main MPU board.  Is this an indicator that something may be wrong with it?
