Quoted from StahlMaster:I was wondering if this machine had any supporting documentation? I'm looking for ALL troubleshooting documentation that came with the Bally ABC Bowling Lanes besides the schematic and operating book that can be had on E**Y.
PBR might also have that stuff. The owner's manual is invaluable for troubleshooting. It has much more detail than many other manufacturers I have seen. All the stepper units are diagrammed out showing exactly what each contact does. Relays as well. Very helpful. If you haven't already tracked one down, I highly recommend you do if you're having issues with your game.
