The circuit for the “Add Player Unit” coil that steps up between players and balls is one of the more complex on a multiplayer game. Do you have the schematic? The pathway during startup and regular gameplay are different.

Also: greetings, neighbor! I life in Afton, which is right next to Woodbury, as I’m sure you are well aware.

EJS I’m free tomorrow afternoon (and will actually be in Woodbury around noon) and all day on Sunday. If you want another set of eyes, give me a call. I’ll DM my phone number to you.

I stopped by @EJS’s house yesterday and we looked at his Vulcan issue. Two switches on the P (Add Player) and BX (Last Ball) relays needed cleaning and adjusting. Working now! It went well having two sets of hands and two sets of eyeballs.
