I'm trying to get a recently rebuilt Gottlieb Big Top started, and I'm having trouble figuring out the startup sequence.
The game powers up when you press the coin switch, and the score motor runs and all the lights come on. Nothing else happens.
As for the startup sequence, the relays on this two player add-a-ball game don't seem to correspond to those listed in the startup sequence on Clay Harrell's site that has been reprinted often here. My "Z" relay, for instance, is the 300 point relay and I don't think it's tied to startup.
I'll include a photo of my score motor, and the section of the schematic that includes a chart about the score motor.
A link to the schematic is here: https://images.pinside.com/5/d0/ae/5d0aec1798e673fc2776bdc816244ba9c0ef8a13.pdf
Questions:
1. Could someone please explain the chart? I understand that the left hand column describes which switch group and the top row describes which position, from bottom to top. But what does the handwritten information tell me?
2. If anyone is bored and would like to take a look at the schematic and describe the startup sequence for this particular machine, I'd appreciate it.

Also, it looks like Clay at Pinrepair.com has updated his site and there's now a full explanation there for the score motor nomenclature.
