Hi miatawnt2b
starting a game makes the Coin-Relay to pull-in - this then makes the Reset-Relay to pull-in. The Reset-Relay closes its Self-Hold-Switch (encircled red in the JPG) --- the Reset-Relay stays pulling until all of the Score-Drums open their "Information-Switch(es) 'Have reached position Zero' " - then the Reset-Relay let go. You could inspect ALL Score-Drums for their "Position-Zero-Switch(es)" to be truely open. You can cheat for the moment by sneaking-in a stripe of paper inbetween the Switchblades of the Self-Hold-Switch (encircled red) on the Reset-Relay. This switch is easy to be found: A short wire runs from one side of the coil on the Reset-Relay to an "switch mounted on the Reset-Relay" - THIS is the switch. This cheating (stripe of paper) is just to learn about "does the Start-up proceed - does the pin kicks out a ball and You can play (?)". Greetings Rolf
