I've been helping a neighbor with his Williams Super Flite. I managed to repair most of the problems but this one has me stumped. The game starts on ball 2. So the game begins by ball 1 lighting up on the backglass, after a brief moment 1000 points is given, the backglass light advances to ball 2 and the ball is kicked into play. From there game play is normal, it advances to ball 3 and then to game over when the ball drains. When the ball is taken from the outhole and placed into the shooting lane manually before start, the ball count also advances normally.
I think I tracked down the problem in the ball count unit but I need assistance. The red circled switch continuity tests as *always closed* regardless of the state of the game. I've pulled the jones plugs from the backbox and the switch tested good manually after that so i know the problem isn't in the backbox.
What switch is this in the schematic? I think I'm looking in the right area. If you have ideas I'd love hear them. If I figure it out I'll post the solution. Thanks.
