All switches work in game until you hit the 3rd drop target in the 4 target play field bank. Then what happens is the 3 pop bumbers act strange.
One pop causes a game reset.
Another pop causes tilt reset.
Another pop causes game to act like a ball drained and it finishes scoring.
In test mode, Switch 34 is constantly on but that roll over switch does not work. (white/brown wire)
Another switch that does not work on the same white/brown line is 28 roll over waterfall button, but does not show up on test.
If I disconnect 3rd playfield target, pop bumpers work correctly.
If I disconnect 34 from roll over and since it is a double white/brown I separate those two. The pop bumper switches register in test. If I reconnect 34, pop bumpers don't show on test.
