Important troubleshooting 411:

Battery pack is made up of 16 cell groups, they must be at the same voltage.

Here is how you can check the voltage of each group, use the probes of your multimeter to measure the 16 individual voltages at these pins.

If all cells are not at the same voltage when the battery pack is assembled then you can blow the trace fuses. Please check every board if any of the groups show zero volts at the testing pins.
