Good luck as well!

So we got back into the battery today and found this:

The BMS isn't looking too clever! Hopefully we can get our hands on another G1 BMS soon :)

Thanks for all the good wishes. If you have a G1 BMS for sale PM me please.

I have no affiliation with the following
http://hybridautocenter.com/HAC4/
They sell used parts for hybrids/ev's. I know they have a Gen II BMS, they may also have a Gen I. They would be very interested in your experience regardless

Kris,
2011 and 2012 are "G1", you can recognise this from all white connectors.

So, obviously they did not get that car and are awaiting the next auction where their buyers can find a 2015 or 2016 car that is not already stripped of some parts... To be continued.
OK, update on the battery swap/upgrade front:
The people that were interested in the packs had backed out, waiting for their battery to drop another bar (likely after summer) and in the mean time another person came forward who wants the upgrade done.
He will trailer his Leaf to me early March and we will do the upgrade then.
Today I heard that finally a new 2015 Leaf with very low mileage arrived at the Dismantler, so I will go there Monday to pick up the battery and remove the modules in preparation of the swap next month.
Also, I finally got my truck to run well with 2 Leaf packs. Range is probably close to 100 miles and it is a blast to drive it.
My only "problem" is now that I have at least 3 working EVs so I need to sell 1 or 2 of my Leafs if I want to keep the truck...

Yeah, a replacement G1 BMS is what ND is after isn't it? Also interested to hear your thoughts on swapping the new double thickness ( https://www.dropbox.com/s/qt88me809t3w5 ... h.jpg?dl=0) modules into a G1 battery case.

Wow, yep - I have seen that happen several times. When an interconnect is missing where it should not (the exception is the service disconnect since the BMS has optical communication isolators mid-pack and at each end to allow the voltage to be anything at that point)
the result of a pack being loaded without interconnect tries to put -380 Volts across the BMS output that tries to monitor a single cell but now sees full pack voltage in reverse, instead of 4V. There is a little bit of protection: series resistors and a zener diode, but nothing that can withstand the brute force of negative 380V that can deliver hundreds of Amps.
I have one BMS where *every* single one of the 24 ASICs that connect to groups of 4 cells (2 modules), has a crater in the plastic chip where the silicon spewed out in liquid form...
Anyway, get another BMS, move or program that IC9 and it should be good to go.
Success!
Cor.
