Hey fellow Quick Draw fans,
My Quick Draw sat in the basement for 25 years and I'm trying to get it going again. I don't have much experience in repair, but getting started learning. I can play several/many games in a row, then suddenly the start button will not start a game (with credits showing). I can lift the playfield and manually activate the S-Start Relay and a game starts as normal. Several more games may pass before it happens again.
I haven't tried to keep track of the match number when it fails, but is that anywhere in the circuit? That's the only thing I can think of that is random. I have checked the anti-cheat switches. Any thoughts on where to look next would be appreciated.
