      Thanks for the advise. I got a person at Georgia Tech to do what you
      suggested, bypassing the short and replacing the resistor, and the AH
      counter is working once again.

      Look at that area for burned board traces, water trails, etc. I
      isolated and bypassed that area and ran wire from screw connector to
      inside board fuse holder after cleaning up burnt area. Coated with
      clear RTV to further isolate.

      don't think BRUSA makes the meter anymore, other brands are
      available. See Xantrex Link 10 product for example.
