Hi all.
I'm a new member and would like to thank coyote640 and others for their contributions to this year-old thread, which I've found quite helpful and insightful. I purchased a Fab U Ball machine about a year ago (pic attached). At the time the thought occurred to me that perhaps it was manufactured by someone other than Skee-Ball, but I was (and still am) far from an arcade expert. Aside from some of the lights other than the score panel not working and the winner light missing, it worked flawlessly for several months. Later, it would occasionally freeze after a game and fail to start a new one. The coin op sensor would appear to trip correctly (the red LED would blink), but the ball release solenoid would not engage and the balls subsequently would not release. Usually power cycling (or hitting the reset button, can't remember if that also worked) would correct the problem.
A couple of months ago, the previously intermittent problem permanent-ized itself. When you power up the machine, the music plays and the lights blink. The coin op sensor appears to trip properly, but the balls don't release. Pushing the reset button starts the music over but doesn't correct the problem. This would seem to be different than coyote's ball-counting sensor problem. Any advice on how to go about troubleshooting? I'm quite mechanically inclined, somewhat less electrically inclined - but I can navigate my way around electrically if I'm helped with good directions.
Thanks in advance for any help,
Paul
