here http://www.ipdb.org/showpic.pl?id=1893&picno=25929 I see: Quick Draw has no Relay Bank near the player / behind the fuses -> the pin has the "AX-" and "BX-Interlock-Relays" (in the picture on the righthandside near the chimes). pinrepair has a nice video -> http://www.pinrepair.com/em/index.htm -> http://www.pinrepair.com/em/index3.htm#axrelayvideo -> in the video at 1:34 to 1:42 a fully working Interlock-Relay. In the video starting at 2:48 is the adjustment shown -> 3:40 to 4:10 a "not properly working AX-Relay -> then the adjustment ...
The AX-Relay is for "Resetting" - the BX-Relay is the "Last-Ball-Relay" telling the brain of the pin "When this ball is played -> You brain, You shall move to Game-Over". And if this relay does not actuate: No Game-Over.
Start a new game -> look at the AX-Relay -> see the movement -> play the balls -> when the secondlast ball is played and -> Outhole -> Shooter alley -> the LAST-Ball appears: the Player-Unit beeing stepped reaches "last-position (in this game)" and the BX-Relay should actuate.
Does Your BX-Relay actuate ? Greetings Rolf
