Hi Dylan
see my JPG - encircled green, B --- look up in the schematics at E33 to E43 and You will see that for stepping the Score-Drums of Player-1 and Player-2 BOTH ( #1 and #2) Reset-Relays are involved. Also You will see that for stepping the Score-Drums of Player-3 and Player-4 BOTH ( #1 and #2) Reset-Relays are involved. In post-1 You write "... but Player-1 and Player-2 Score-Reels do not zero-out ..." - what exactly does happen ? Please toggle-off the pin, unplug the 110VAC plug (Safety Reasons) and step all the Score-Drums of Player-1 and Player-2 to "position one" - then plug-in, toggle-on, "start" a game - wait until no Score-Drum of Player-1 and -2 is stepped anymore - WHAT do the Score-Drums show ? (theoretical example 38610, 43720)
I am not familiar with Bally pins - look here (WILLIAMS) https://www.ipdb.org/files/415/Williams_1968_Cabaret_Instruction_Manual_no_schematics.pdf on page-15 (ori-13) on the bottom: Three switches do actuate --- in my JPG "green A, green B, green C" I show on Air Aces, tens-Score-Drum of Player-1 the three switches and also I show the colors of the wires soldered-on. Please take-out the tens-Score-Drum of Player-1 - try to locate these three switches - see how they operate (open / close) when You manually step the drum ?
See in the JPG "blue stuff and brown stuff" --- when the Score-Motor is running (trying to reset, to step the Score-Drums forward to position-zero) --- within a full revolution of the motor: #1-Score-Reset-Relay does rhythmically activate - deactivate - activate - deactivate etc. - 10 times in a full revolution of the motor --- and the #2-Score-Reset-Relay does this 12 times in a full revolution --- question: In Your pin do the #1- and #2-Reset-Relay rhythmically activate - deactivate - activate - deactivate etc. when Your pin does try to start / reset ?
Your answer in post-3 "... cannot test if the game-over-relay trips ..." is not an answer to what I asked You to do (my post-2) - Please WATCH the Game-Over-Relay while You toggle-on the main power switch - does the Game-Over-Relay actuate (while You toggle-on the main power switch) ? Greetings Rolf
