I’m currently working on a complete extensive shop out of the 63 Williams Big Daddy I got at the Tulsa auction in February.
I’ve gone through every single switch, relay, mech, score reel, stepper, etc. with a fine tooth comb. Having been a Gottlieb EM guy for most of my pinball collecting hobby I’m very impressed with how well these early 60’s Williams games were built. There is nothing on this game that hasn’t held up mechanically that I have discovered on the game. I’ve gone through and dremeled/swabbed every switch, adjusted switch settings where needed, disassembled all the score reels and cleaned and lubricated them were indicated, brushed the jones plugs, etc. Everything looks functionally sound and set up properly.
I put the whole game together on Sunday and turned it on for the first time and the score motor continues to run. I've disconnected the coin door and the playfield with no change.
In going through the schematic it is unclear to me how to interpret what can cause the score motor to run. On Gottlieb schematics it's a simple rung they show on it relative to the score motor. Not the case here.
A friend looked at the schematic and pointed me to the target relay, 25 cent relay, game over relay, 5 point relay, and 50 point relay as locations where a switch resides that can cause the score motor to run. I don’t see how you interpret in this schematic that it can cause the score motor to run.
Can anyone shed some light on how to interpret this schematic regarding switches that make the score motor run?
