Williams Big Guns - System 11B
Intermittently scores 10 points when the ball is fed into the shooter lane.
Have checked diodes on all the stand up targets as well as the switches in the shooter lane, ball trough, cannons, ball popper, and the king’s chamber.
No multiple switches in switch tests.
Slings switches have a good gap.
Knocking on the playfield with my fist doesn’t trigger any switches in switch test.
Not sure what else to check.
Always 10 points. Doesn’t happen every ball. Doesn’t seem to correlate to number of balls locked.
Scratching my head. Any ideas?
