A missing screw in the plate below the drop target was causing it to tilt slightly out of alignment. Replaced the screw, fixed the alignment and the ball is no longer getting stuck back there
Replaced the two rollover switches at the back of the playfield and the one in the right orbit
Replaced the leaf switch, the drop target is stuck in the up position still (continuously) now. I think when i was re-soldering the wires to the switch i may have bent them out a little too far and they are now impeeding the mechanism from dropping.
Ball still getting stuck behind drop target. I suspect that switch is intermittent too. Let’s replace it when we do the others.
Drop target on right ramp wasn’t coming back up after being engaged. Looked online and found someone was having a similar issue. Suggested loosening the adjustable screw, which solved the issue. If the screw is too tight, the drop target doesn’t come down low enough to actuate the leaf switch that causes the game to register that the drop target came down. Loosened the screw solved the issue
Closed problem report
Ball sometimes sticks. I think the drop target doesn’t always drop.
