Have gapped that switch, so the 3 blades are independent of each other.

When like that, the machine will not turn on (ie: no lights or anything) but when i briefly touch either of the 2 shorter blades to the longest one the machine turns on.

Again, when the ball trough switch is closed, the score motor runs continually, but can't start a game.

Will wait till Kraig gets here at lunch time and try reconnecting the missing wire to the relay on the coin chute and see if that does anything.
