More weird stuff.
The #1 and 2 lock switches and the shooter lane switch register perfectly during switch test. During gameplay, the machine doesn't realize the ball hits the lock switch, so it's locked but never spits out the 2nd ball from the shooter lane.
Additionally, before game start is pressed, if a ball is either in the lock, or the shooter lane, the game won't start, states "PINBALL MISSING",.. it doesn't recognize where the balls are. Trough switches seem to work, as when all three balls are in the trough the game always starts.
With a ball in the lock or shooter lane, the game goes through the missing pinball coil firing sequence. Once the balls return to the trough, game starts.
This is repeatable 100% of the time. And messing with, wiggling switches doesn't work.
Thoughts?
Thanks for everyone's help getting this awesome machine running!
