u/Gugs-

Hi all,

I have having an issue with a JK BMS which I wired per the manual, but I can’t get to start when I long press the power button.

Here are the knowns:

Voltmeter reads correctly 73V at both ends of the battery.
All balancing cables are connected.
b+ goes to last cell positive
b- goes to the first cell negative
B- goes to the first cell negative
Shorting B- to P- did not work
Putting a resistor between B- and P- did not work

Any ideas of what could be the problem?

Thank you!
