    Hold please. For some reason, that gets me every time.

    Right ramp enter (opto) controls the super skill shot. If you are getting a super skill shot at the start of a ball without plunging, check your right ramp enter opto in switch test. Something is in the way of the opto or it is faulty (clean it, check it, replace it).

      This actually raises a good point. That opto always tests good. It isn't dirty or anything. Seems fine and always works during testing.
      One thing I noticed that happened a few times - when you have 2 balls locked sometimes it will randomly give you the third ball like you'd locked it. It isn't something that happens a lot, but enough to have noticed it. I always shrugged it off and thought maybe that second ball locked hit and bounced up enough to trigger that third switch (or something). The Super Skill Shot thing also only happens once in a while.
      If opto 44 is the one that registers the skill shot that would be the same for locking the third ball. That would indicate to me that something is flaky with opto 44. It just fails occasionally but not where I can manually reproduce it. Cold solder point maybe?
      I think to test this, I'm going to reheat those solder points on the optos. If it still happens, I'm going to swap 44 with 46 (center ramp enter). If that stops this behaviour, then I can set the game to virtually lock balls until I get a new part to replace the opto.

    I had a similar problem with my Houdini last year. I have very few plays on this machine I bought new. The ball diverter coil underneath the chest(left rear of playfield) burned up like yours did. It took out the fuse and transistor too. I wonder if they aren’t having a reliability problem with these coils.

      If I had to guess how mine failed, I'm going to speculate the ship post got stuck halfway from the roll pin coming out. This caused a ball to remain stuck behind it. The coil repeatedly fired because it knew a ball was there and it was trying to dump it from the ship. After a particular amount of time, the transistor overheated and cooked closed. This fed power to the coil until it melted and then the fuse popped.

    I’m surprised such a new game already needed a new coil & had a bad switch??

      It looks like all of these issues are from a single faulty opto in the ship. I can't really fault American Pinball. It's just a third party device they're using. Of course it probably would never had happened if they used actual switches. I'm not a huge fan of using optos. They're cheap to install, but often expensive to repair.

    All I hear is "sh!t post" 😂
