Probably a good idea to go through all the stepper units I would imagine some are gummed-up
Quoted from pinballdaveh:On your 3rd pic the ball count unit horizontal switch stack, the lower normally closed switch looks bent and not closed correctly. On the 1st pic shouldn’t the red spring connect to the post just left of where it is now?
Yeah that 1 switch blade looks pretty bent-up a good switch adjuster tool is good to have https://www.pinballlife.com/ultimate-leaf-adjuster-tool.html along with a dental mirror in some cases

looks like a loose switch stack on the score motor , first straighten and tighten things up before adjusting the blades ( if needed )

I also noticed on whatever stepper unit this is it appears the Bakelite plate is "out of square" causing to fingers to be misaligned.
