Quoted from Black_Knight:

Thanks Howard.
Looking at it with some coffee today, I will block off the bonus relays and see if that does it. I’m assuming it’s the EOS switch on the unit.
As I mentioned, all the score reels stop at 0 so that tells me the 20 listed there should be good. But if there is a central wire for me to block all of those let me know. I don’t see anything on the player unit.
the letters just outside the first box- M.B. IND-D with a weird symbol. Is this a make/ break from the score motor? How do I read that to determine which one it is? D - 4th one from the motor?
Any reason you left it out of the box?

That is a Make Break switch on the scoring motor. The switch stack would be the INDEX switch stck, switch position "D".
