Just picked up a gottlieb big shot. At power up, ZB triggers and relay C locks, score motor spins nonstop. The tilt light comes on as well but it is not tilted. I checked and don’t see any touching leaf switches at C. If I reset ZB it just trips right away. I have a video but cannot figure out how to attach it.

You can post the video on You Tube and link to it... I've done that before

What are these switches doing when this happens?

Forgive me, not the best at reading schematics, although I do have the entire original schematic. Is this QB1? There are several leaf switches on it and hard to tell but most if not all appear to be closed. How do I find Bonus Unit Runout Switch?
