Not to threadjack, but i have a new issue with my GE...

Last week all of a sudden, when ball 3 starts the game immediately goes into satellite multiball (it apparently thinks ball is in dish). Further investigation and i find that neither magnet is actually working. All fuses are good. Both high and low voltage are being provided to the mag processing board, although the high voltage was like 80v, not 50v. There is also a 9VAC input line on the schematic (header pin 12), that i cannot tell where it comes from. I could not find any voltage on that line. I removed the board, reflowed the headers, and some other joints, and reseated the PIC chip. I put it all back together, and it worked fine. For about 3 days.... Now i am back to the original symptoms.

Anyone have any ideas?
