Hi DJ_Charette
"first" I would like You to look (once more) at some Jones-Plugs (on the male side AND on the female side: Wires soldered-on ?) - and some Switches on relays (Score-Motor).
"Second" do a little manipulation*** on the Make-and-Brake-Switch on the Game-Over-Relay.
"Third" (if no look): We use some Jumper-Wires for checking / forcing a No-Match-Replay.
From ipdb-schema (around 20-24, C-F) I made a snippet of the area. "Green" line: Replays are made by the Score-Reels - a Make-and-Brake-Switch on Game-Over-Relay is "as shown in the schema) -> the Credit-Unit steps up.
The "orange lines" show "reaching Game-Over -> the M+B-Switch on Game-Over-Relay is moved -> eventually Player-1 gets a "No-Match-Replay".
I encircled "red" the switches / Jones Plugs You should check. NOTE: In the lower right corner I show again the "Switch on Player-Reset-Relay". I believe: An Error in the drawing - I would like to have an Normally-Closed-Switch.
The little manipulation***: It is awful to ALWAYS PLAY 3 OR 5 BALLS until You reach Game-Over (for testing the No-Match-Unit) -> If You manipulate the M+B-Switch -> during play the No-Match would fire (we are looking for a fault - we do not want to play) whenever *Match" AND the Score-Motor turns (through SCM-4A. IF YOU MANIPULATE THE M+B-SWITCH ON GAME-OVER-RELAY: Wrap around the three solder-lugs of the 3 blades a blank wire -> -> Not only at "GAME-Over - ALSO during play "the No-Match does fire".
If "No luck" -> we will use Jumper-Wires -> forcing current to flow / checking switches ...
Greetings Rolf
