This is a tough one with no obvious answer. It would be unlikely, but not impossible, for all your SCRs to short out at once. Is it possible the bridge on the rectifier board went bad? Thats a possibility along with a bad 6821 chip on the MPU. You could swap U10 and U11 and see if anything changes.
