Quoted from amxman:
Was looking at WOW decagon unit and saw a old note wedged by the unit.
The note looks to be printed by Gottlieb, it matches the rest of machine. Thought it was interesting.
Comp. CIR. To Subtract
"Ball Count" Unit.
Opens CIR. To SUB. Coil.
If what I'm reading is correct, when the "second" SW completes circuit it then subtracts "ball count".
Am I to assume the switch stack is what this note is talking about?
I will put some pictures up when I get a chance.
Yes, that label describes the three switches on the ratchet side of this stepper, which is called the "Litebox Advance Unit". Below is how those three switches should work.
First and second switch should be closed. Third switch should be open.
Any Position Above Zero (WOWs are lit)
First and second switch should be open. Third switch should be closed.
