Hi jkroeck25
the logic in the pin is "a relay called '1-9 RESET-Relay' " is made pulling-in "when it is time to reset the bank 1-9". The manufacturer says THIS is "liberal" - IF (if) You, operator at these times WANT ALSO (forced) the reset the 1-9-bank WHEN a new Game is started: With the Adj-Plug in "cons position" WE let current flow to reset the 1-9 bank - because: When a new game is started: The RESET-Relay WILL for sure pull-in (for to reset the Score-Drums) - so we (Williams) simply mount an "Switch on Reset-Relay" to make happen what THESE operators wanted ...
I advice: Adjust the Adj-Plug to "conservative" - AND PLAY MANY games - IF (if) You (then) REALLY want the 10-Ace ALSO reset at "starting a new game": We can do an modification - an "Hack" by "somewhat adding an relay or a switch or a microswitch using the movement of the armature of the pulling Reset-Relay" to ALSO force the resetting of 10-Ace.
I strongly advice: FIRST Adjust the Adj-Plug to "conservative" - AND PLAY MANY games --- THEN think of "Do I (You) really want to do this hack ? (and eveentually want to ask in the forum about "how to do"), greetings Rolf
