      In case your curious, my shunt is slightly different:

      http://aaron.birenboim.com/EV/MattTracy/ForceFuses.jpg

      After getting the manual for the Brusa Ah counter, I have some
      more odd data.

      It appears that the controler will not allow voltage
      to sag below 127v. Thats 10.5v/battery. Thats the
      number I see for a totally dead 12v PbA battery.
      Problem is that it seems a bit conservative to limit
      voltage to that level UNDER LOAD. A rule of thumb I've heard
      is that voltage should never, ever go below 6.5v for any
      12v battery. Thats a dead battery. Wouldn't a limit
      of something like 8.5v/battery under load be reasonable?
      (102v in a 144v pack)

      Also... I never see a current above about 110 amps.
      Would this be expected for a 92 force with a AMC300
      controller?

      I have not contacted Solectria yet. Perhaps I should.
      I don't know what they might be willing to tell me
      about a 92 force. I'd sure like to get more documentation
      on that controller. Brusa was very nice and sent me
      some... but its in German ! ;-)
