I am working on a different pin after being out of the game for a few years. Looking for some pointers on a Sega Harley-Davidson.
The game boots up, but the raising/lowering bike just runs constantly (assuming the limit switches aren’t working). None of the ball trough switches work so the game is constantly saying “4 balls missing.”
Once in a while I can finally get it to start a game, but when it starts, it will auto-launch a ball around the upper loop and promptly shoot sparks from the CPU board in the backbox out toward the player if the backglass is removed. I was able to replicate this issue twice (and I don’t really want to try it again). It appears to be originating around the connector “Switch Columns” which checks out since other switches are having issues. I have already replaced the CPU board so I am not sure where the issue could be. I do not see anything glaringly obvious like a staple caught behind the CPU board or anything like that. How can I test for this issue with a multimeter?
