sbmso and shunts

[jwals...@gmail.com]

hello everyone, mt sbmso is showing a  .643 amp draw on battery and a .589 amp load. there is nothing connected to battery only the shunts. i used Oberon Robinsons booklet to test the shunts and the shunts move with the change in amperage. i attempted to change the shunt settings and the offsets with no change. could there be high resistance in the ribbon cable for the cells causing this?

The resolution of those photos is to low I can not see anything.

The shunts need to be connected when you power ON the SBMS0 so that zero shunt calibration is done correctly.

If you can upload a larger resolution of the diagnostic screen photo I may be able to understand what happens.
