So, all the switch cleaning that I've been doing with the emery board had been leaving a dust on contacts. Going through all the contacts with a moistened q-tip has taken care of most of my issues.

Now the only thing left to figure out is the game over relay.

The game gets to ball 3, and the match number shows up, but the game doesn't end. The lights above the drop target bank and the pop bumper cap flash on and off.

O relay, BX relay, nope.

Q relay? Nope.

Ball is in outhole. O relay activates.

Won't stop at the end of bonus and go to game over.

Something in the roto-brain? I'd like to know know what you think. The game now works as it should other than that.

I am almost there. Thank you for the help.
