Go back to the switch test. Remove the balls and reset the Drop Target bank so they are all reset.
Your switch test should read "0".
Flick each switch in the trough and make sure that he corresponding switch is the correct switch as per the manual. Simulate the ball in the trough, and watch what the switch test does as it rolls over each switch. It may simply be a matter of adjusting the switch. I had similar issues with Fathom.
Just tryed that. The only way I can make the test read 0 is to hold the micro switch ( 28 Ball Release) arm down. All switches then register as they should including the other problem switch 33 Side Saucer.
I really don't know what to make of it but the other thing that happens when I do start a game by pushing the first ball past the "ball release 03 solenoid" ( this then triggers the solinoid to release another ball after the first one drains). Once I've lost all the balls in the game, I have to turn the machine off and then on again. As simply pushing start again and pushing the ball through the ball release only works once per start up.
Sounds like Switch 28 is not wired correctly. a "Normally Open" switch is incorrectly wired as "Normally closed".
