I’ve got a scoring issue with my father in laws Pit stop. When the ball travels through the top center roll over lane(200 pt. advance 5) it continues to score in 500 point increments and eventually quits and goes into a game over state. Once resetting the game plays and scores fine until the center roll over is activated. I have the schematic and started looking over the 200 point relay and roll over switch which look and test ok.

I'll need to see a high quality scan of the schematic from (for example) Staples ($2) or Kinkos ($6)
Not the crappy paginated one on IPDB

I will upload a few pictures for now until I can get to one of those places. I am quite a distance from either.

There's a normally-closed switch on the score motor (the schematic says it's "2-D") that should open to deactivate the 200 point relay after the second "100" is scored. That switch is probably stuck closed.
