With the machine off, manually operate the bank reset coil plunger and check if the switch armatures all lock in place during reset.
Update:
1. With the game off I can manually reset the the bank of relays, when I power on the machine the tilt relay and game over immediately fall.
2. I have pulled the lock relay and checked resistance. I have 14ohms and I understand it should be 14.2 so I think I am good there.
3. I tried to manually hold the lock relay engaged when starting a game, and it made no difference. The game still goes through the reset sequence but ends with game over and tilt lights on the backglass and no game to start.

If you unsolder the wire to the tilt relay coil will it reset correctly?
I am not sure I can be of much help other than to say that quadruple checking the tilt and slam switches is worth your time. I chased something similar that I had induced by gapping a slam switch open when it should have been closed. Also- be certain you know how many there are and that you checked each.
Redundant I know- but in these cases assume you were wrong- re think- and then recheck.

I’m stumped. I’m a novice at best but here’s where I’m at. The machine is still acting the same. I checked resistance on the lock relay out of the machine and it was 14 ohms which I believe is okay.
Here are pics of the tilt switch and bottom kick off switch. The tilt switch is closed and the kick off is open. By what I’m reading on the schematic, I think they’re both NC but I’ve tried them both ways based on someone else’s machine. Maybe I’m in the wrong spot.
This thing is kicking my ass.

I don't have a Fast Ball schematic (maybe you could scan yours and send it to ipdb.org), but here's the Game Over trip relay schematic from Action Baseball from a couple years later.

You might want to look into the various circuits that can fire the Game Over relay in your game. In this case I'd start by checking the resistance from the yellow wire on the left to the red-yellow wire on the Game Over trip relay coil. If it's less than a few ohms that would explain why the relay trips. Then I'd check
- that the Inning Unit resets as it should
- whether removing the Inning Adjust jones plug changes anything
- whether the Lock relay switch is stuck closed or shorted
- etc.
What does the Game Over relay look like on your schematic? (If you post part of the schematic please rotate it the right way - thanks.)

I know this is a long shot. But check the leads coming in to the nc tilt switches. Make sure a wire or solder joint isn’t loose or broken. Just had that happen w a non tilt switch problem.
