Out hole relay is cleaned and adjusted now. Didn't appear to need it. no change in game. Game is set to freeplay on Replay. The Replay/Add A Ball/Novelty Jones Plug setting is a bit odd. Is the paper stapled a little low or should the red line on the male end line up with the paper? The manual shows a Star shaped selector for this option.
Current state of machine; Powers up, Left flipper activates GI, start button works to start a game. reset sequence works, score reels reset to zero and ball kicks out. I have it set on 3 Balls, as soon as the "On Bumpers" rollover is activated every pop registers as a lost ball. usually one plunge kills the game back to GAME OVER. Scoring does not register at all. Reels are dead unless I manually activate. They do reset to zero on power up. I have noticed the Match unit locked on once or twice during testing but cannot replicate.
I have completely gone over the backbox, disassembled the score reels and cleaned and adjusted, the ball count unit, match unit and Replay unit. They all work smooth and in good order. I am comfortable in backboxes, not so much under the Playfield.
This is my first Williams, I have worked on and solved many issues in Gottlieb Wedgeheads. I am far from proficient though.IMG_20200425_200428 (resized).jpgIMG_20200425_200447 (resized).jpg
