Appreciate any guidance on getting this gremlin fixed. After complete refurbishment, removed and replaced all components on playfield for restore have one little problem can’t figure out.
The treasure chamber kick out isn’t working. Going through the test mod the #3 solenoid pulls in (treasure chamber saucer), when switch is engaged will make sound and add points, have Alltech Systems MPU board, recently refurbished solenoid driver board. All other solenoids work properly.

Any clues on what to look for.
My givens are solenoid is working per test, switch is working from sound and scoring – what am I missing?
Thanks.
FYI want to sell this and move onto next project – seeking – Bally - multi ball - wide body.

can not figure out how to edit the post to new group? I am new to posting on forum. any ideas

Switch does register properly with ball and coil works during test, could something have happened to MPU board it’s a new Altech. Wonder if there was update to board or others have had problem?

Tried this - yes it does get kicked out as the other two.

I was wrong. In attract mode it will NOT kick it out. The other two will. If left in and when first turning it on it will kick out. So switch is not sending signal to some part of system. -

in test mode it works on number 03 as identified in table for self test #s. I swapped play fields so don't have a bases if that play field ever worked. I have two play fields and used the one which was in machine originally as guide when rebuilding. The wires going to switch are brown-white and white-yellow just like the extra play field I still have, that one had worked prior to refer-bush. When switch engaged it only scores 10 points and makes sound and advances the bonus area by one step. 10 points is what a rebound switch will score so why is that?
I traced all wires back to sound board and MPU board and look like in correct position for the four plugs they travel to. I have not tested continuity for all wires yet - think I should? Wires going to solenoid are double yellow single orange.
the 10 points scored is weird?

the top bumper scores 500 points but does not engage solenoid.

solenoid wires are double yellow wires and single orange and and looks black or green?

now I may be getting close when the top center target switch is engaged has two white-yellow and brown-yellow wires it will engage the treasure chamber saucer solenoid. now how do I fix that?

solved
on the MPU board plug number J2 position number 13 and 14 where reversed. thanks to all for creating the thinking process. not sure how these where reversed since I did not mess with the plug wiring. this was play field I never used but used it to refurbish the whole game. NOW it works ---.
