I have an interesting problem on my Fathom. I can't release the ball from the TOP lagoon saucer using the six drop targets on LEFT.

1) Do I have the game play rules correct here?

Good Situation:
Lock top ball. Three blue targets rise. Knock those 3 blue targets down. Ball is released. Good.

Bad Situation:
Re-lock the TOP ball again during multiball. Knock down all 3 blue targets on left. Ball is not released. Bad.

Notes:
1) Is there any set of dipswitch settings that could cause this?
2) Why is it that I can drop all six targets on left, then they all reset (this tells me the switch is good to know when the target is down)
3) All 6 targets raise properly when in coil test or game play.
4) Since Top Saucer ejects well when you drop the top 3 blues, we know the saucer switch and eject are good
5) New alltek CPU in there, so expecting a perfect CPU experience. Had the same behavior with an old board in there.

Thanks for the ideas and troubleshooting tips!

Hopefully, (this time) I have a correct understanding of how this should work.

Here's another clue...

During multiball, when I re-lock the TOP saucer ball, when I knock down the three blue targets on LEFT, I can see and hear Fathom trying to drop the ALREADY dropped middle blue target. By comparison, if I re-lock the RIGHT ball, and then knock down the three green targets, it snaps off the eject in the saucer quickly.

Correct. This will be an easy fix. Only #42 is registering, so the other two were never registering, I only thought they were since #42 works, and the ball would be released after 42 went down the first time.

Thank you!

Solved! Thanks for the help. Another easy one licked.

1. Took pictures with cell phone camera of the area
2. Pressed down with thumb into the two switches (can't see them with playfield in upright position)
3. cleaned contacts with dollar bill
4. ran switch test

It's good to know I can finally adjust switches properly that I cannot see =)
