Metallica (Premium)
Stern, 2013i have an issue on my metallica premium. During play, with drop targets still in the up position it has started awarding graveyard multiball. I can't identify anything consistent happening just before it. Any ideas? I've tried checking connections. Not sure what else it could be?
thanks for any advice
I had that exact issue with my new pro. It was the loose cross opto connector unerneath the playfield (on the opto pcb board). It registered hits from vibrations on the playfield.

I’ve worked on 2 Met that had this issue, aside from new opto set and securing connectors, I needed to actually bend the ball guides inward a bit to make certain the optics were properly aligned, the receiver board needed to be directly in the center of the red circle of light from the emitter to fix the problem 100%.
