I know it's not technically a pinball (athough it does have a pinball boardset), but have a questions, and wondering if any of you might have any insight ...

I picked up a Hyperball for next to nothing last week, and have been able to solve most of the issues. The one issue I still have is the ball return auger, which currently doesn't work. I know there's supposed to be 125v coming out of the I5J4 plug, which I pretty much have (128v) actually at all times, until I plug the ball return motor in, which will then drop my voltage to around nothing. I took the motor out and applied 125 directly to it, and it works fine, so it's not jammed up. Kind of scratching my head on this one.

Edit: The only thing I've done on the power switching board so far is replace the triac. I've tested everything else, and it all seems to check out.
