One year forward, three years back.

 You may have read in the previous post that the BMS seems to have blown a chip, we still have not figured out what is going wrong, but now we consider ourselves very lucky.  Let this be a WARNING for all of us, plug in your BMS AND check that it is actually working.  We have TWO completely shorted out cells sitting at zero volts.

The bottom two modules of the inner stack read ZERO volts. These represent the center modules 12 and 13 in the leaf pack, they usually have the main disconnect between them.

  1. Hi,

    we have lost two BMS in our workshop over the last two years, so I made a testing device to check sensing wire harness wiring! I can share that with you if you want.

    I couldn't find a way to contact you, would be good to show you what we got and learn exactly what your mistake was :)
