2013 MX, contactor open and flashing: Post Error (23) Board Vpack error (21)
« on: August 30, 2023, 05:32:55 AM »

I connected the MBB and the BMS to the computer with TTL to USB thanks to the information I was offered here. Attached is what I get from the MBB when I turn the key and it just keeps going like this. Also attached is the BMS data from the MBB.

I really appreciate any help understanding what may be causing the problem. Thanks.

It was the FET Board not being closed and making the Sevcon try to get power from the low power B- and blowing that fuse. Bypassed FET Board as a temporary solution, but will be running with full BMS protections soon. I enjoyed the test ride! Only got here with help from the community! Thanks
