I'm wondering if the OP ever fixed his issue? I'm having the exact same issue but my issue is with Rob Zombie. The kick out hole underneath the mini playfield keeps blowing the fuse. My thought is that the Pinball Life knocker is causing an overload in the number 1 fuse but still can't figure it out. As long as I replace the fuse, the game operates just fine.
Any help would be greatly appreciated. I've also sent Charlie an email.
