I brought home the King Pin over the weekend. I plan to do a full cabinet repaint eventually. For now, I want to get it working 100% and will thoroughly go through it mechanically before cleaning and restoring the playfield.
For starters, I am wondering if I need to disable the coil inside the coin door? It's still got power going to it and when I press the start button the reels (slowly) reset (I need to service them -- a couple of them struggle to get to zero but eventually do) but it doesn't kick the ball out right away. The score motor keeps running until I wiggle the little bar (shown in the picture below) inside the coin door and eventually get it to the right position for the motor to stop. Then the ball kicks out for Ball 1 and it goes through a normal game (Balls 1-5, then to Game Over). What do you think is causing that, and what role is that coin door playing in that?
