      I have an AC-325 which is apparently a little less powerful than your
      UMOC425. I've never unbuttoned it. The only documentation that I
      have is the Solectria Owner's Manual for Universal Motor Controllers.
      This manual doesn't have any schematics or diagnostic information

      No, I don't have any ideas. I've always been much stronger in design
      than in troubleshooting or repair of other's designs.

      I'll send this note to the Solectria listserver to see if others can
      help out on this matter.

      It's my opinion that if Solectria is not going to support us when
      trouble arises in these units, then they should provide us with
      schematics, typical waveforms at different points, and a design
      spec., etc.

      ATTENTION LIST: This controller is in a college-built hybrid that is
      going to the Tour De Sol this spring. Any help would be appreciated.
