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.
