Gang:
I have a weird issue that seems to be getting worse with time.
Purchased a Sorcerer several years ago that would never play a game as upon power up, the outhole solenoid would fire repeatedly. Figured it was a switch issue and had several projects in front of it, so I folded it up and the game went into stasis for 3 years. Recently did a full restore on the game, reworking all the boards, bulletproofing mods, etc. When finished and the game was reassembled (about a month ago), the outhole solenoid would fire once, MAYBE twice, before going silent and the game would enter attract mode.
Now, several weeks later, upon power up, the outhole solenoid will fire repeatedly - any where from 6-20 times before stopping and allowing the game to enter normal attract mode. It is consistently getting worse. Note, that once the game enters attract mode and is played, the issue disappears. The game can be played over and over again without problems. It is ONLY an issue at initial start up.
Switch mode test indicates that everything checks out good. Could it be a transistor issue on the board, or a micro switch getting flaky? That solenoid does fire continuously even when open, for what that is worth.
Thanks in advance for weighing in!
