I'm working on a Grand Slam trying to revive it from the dead. Never worked on an EM, but electronics don't scare me... I've got it mostly working, but I'm having difficulty understanding the correct start up sequence from the manual/schematics. In what sequence should the roto target find home / score reels reset / ball eject into shooter lane?
When I push the button to begin a game, the score reels do not reset to zero and the roto target doesn't stop spinning. It is missing springs, which may mean it's not landing in the right place to make contact, but I've tried manually moving/holding it to a centered position and it still never seems to continue the game start up. If I manually move the ball into the lane, it will play and score, albeit with the reels never going back to zero. I feel like I'm close to getting it working, but I'm not sure where I should be looking at to finalize the proper start up. Any guidance much appreciated!
