Thanks again for all the help everyone.
Q - When You start a game -> Does that "Relay Bank" reset ? Are there tags with text (on / near) the Relay-Bank" - (a relay named "Game Over (Relay)" ?
A - The bank appears to reset and I do have tags.
Q - Look in the picture / in Your OoS: Underneath the playfield (to the right): That huge "Stepper-Unit" see it ? (You have started a game) Hit a lighted drop-down-Target -> That Unit should want to step-up - do You see the "direction of turn" ?
A - It does turn from left to right when hitting a drop target if you are looking at the brown disc.
Q - Pull the 110-Volt-Line-Cord -> be nice and gentle: try to step that Stepper-Unit "the other way" around - we want that Stepper-Unit at ZERO for Our next test. By the way: Can you manually step-up / step-down that unit ? Dirt / Grease / "loose parts" around ? The spring (helping to step-down) in place ? wires soldered on ?
A - It moves in either direction just fine manually.
Q - OK, You have manually stepped that unit down to Zero. -> Plug-in the 110-Volt-Line-Cord and start a game -> please report "The pin is doing ..."
When Your are given the first ball -> play the ball ONLY HITTING the BUMPERS (NO BONUS !) -> let the ball drain -> please report "The pin is doing ...".
Is the second ball given to You ? -> play it (only hitting the bumpers) -> ball -> -> "GAME OVER" ? Please report.
A - With only a bumper hit and then drain, the stepper unit begins and lights the thousands and gets stuck.
Q - The relays in Your OoS ?
A - Here is a picture of my relay bank:

Here is a better video of what exactly is going on with the stepper:
And a few more pictures of the stepper that will hopefully help:
