Mjalexan, thanks for the pics. Just wanted to see if you had the same wire config.
If I’m playing a game with several credits, when the ball is on the lower playfield and hits what I think is target #2, it will add players to the game. The other half of the time, on the lower field, hitting same #2 target, will shut down game and start a new game from zero. Not rebooting, just like you pressed the credit button and started a new game. Two other weird occurrences.... while on the lower field, the right Outhole will activate repeatedly sometimes. Also the tilt light will appear on the glass, but not tilt play, just on. There are the symptoms.
Beautiful original MPU. Switched to Altek with no change
All connectors have been re pinned on all boards
Switch matrix you say. Maybe. All caps AND diodes have been replaced on all lower level targets. Diodes on credit button, and right saucer changed.
Can’t seem to find anything pinched or diodes touching.
Been over the lower playfield and #2 switch, and even the upper lever targets which are tied together.
I still think it’s somehow in the matrix or connectors.
Any ideas? I’m open to anything. Plus I forgot to secure the lower playfield, and went to put the main field back down and got hit by lower. Stuck a coil lug in the side of my face!!. I’ve about had it with this thing.
