Quoted from CALencio:
I think I've finally had enough airballs from the Jesus/Maude rubber post split that the spot light has finally quit on me. No more jiggling has got it working. Any pointers on fixing it or replacement parts? Could it be a loose wire at the light itself?
I would recommend taking a close look at the lower playfield window to ensure that it is flush to the playfield. If it's slightly raised in the top right corner, then that could be the cause of your airballs to that post. Similar conversations have been documented about the upper left side contributing to airballs off of the right stand-up lock switch on the left ramp. I have had to adjust my window a few times but it really makes a difference. To adjust, you'll need some trial and error by either loosening or tightening the fastners underneath the playfield that secure the window and then putting the playfield down to test how flush it is
