So… I’ve been working with this machine for about a week now. Best guess, it sat for years until I got it. Slowly making progress while waiting for a copy of the manual. I’m anxious to see those relay mappings.
Here are the current symptoms… any obvious insight?
Replay button does decrement the credit wheel. Does turn off game over light. Dies reset score to 0. Does not add balls. Does not power the playfield. I can get a game playing by manually activating the coin and game relays.
Outhole switch does run the score motor. Does not decrement ball count. Does not activate the outhole coil to eject the ball.
Ball count unit does light up 1-5 with manual actuation of the coils. Continuity check suggests all contacts ok. Mechanism moves freely.
In a power off state (unplugged) some of the switches on the coin and game relays have continuity, even when open. (Sorry, I don’t have the switch names until I get the book) without the switch names, I can’t figure if that is normal or a short in the wiring.
From what I can see, the coin relay is wired to be self holding. It does not.
Visual check suggests all switches are set correctly. N.O. / N.C. / M.B.
Obviously, I’m missing something. Maybe it will be obvious when the book shows up in a few days…. Until then. Any thoughts?
