Just so I fully understand your going to bare wire an I8 (bmw) charger to recharge the main battery at 3.6kw. Am I missing anything?

Figured it outSo peter we are talking about connecting to terminals Ac1 and Ac 2 in the set port which appear to go to charging port correct?
But how to get the charger to output voltage?and what should it be?
The bmw charger is only 10 ampsJust so I fully understand your going to bare wire an I8 (bmw) charger to recharge the main battery at 3.6kw. Am I missing anything?

Is the Roadster free-rolling? If so, the Roadster shouldn't allow charging. Imagine the Roadster starts rolling away from the outlet while actively charging. That's why it won't allow charging.Most likely due to low power?
Can’t charge in tow mode!
I have 6 troubles on the display !Is the Roadster free-rolling? If so, the Roadster shouldn't allow charging. Imagine the Roadster starts rolling away from the outlet while actively charging. That's why it won't allow charging.
Also, check the HV battery voltage from the diagnostic menu. It's in the ESS sub-menu.
Thanks do you have this set up I can rent ?Safely trickle charge a bricked pack in/out of car - solution
By far the best diagnostic/rescue solution to date.
Do you have pictures of them, or the error ID numbers?I have 6 troubles on the display !
There's a chance at recovering the HV battery if the Roadster hasn't been charged since January of this year. However you will need to get the HV battery voltage from the diagnostic menu.It appears the car has not been charged since January
And can’t get to eSS menu
What to do ?
Can I call you?
Ok thanksBy the time it would get to you it would be quicker and faster to have the boards made, the numbers and files are all on the thread. I had to get them delivered to Miami and it was fast. Delivery from here to the US is ridiculously expensive and slow.

Does Nicks Gerber file included populating them? As well as ends required?PCBWAY and JLCPCB both offer fabrication options, getting 11 or 12 boards made is relatively cheap, having them populated is expensive. But the quoting process is free, you just upload the gerber files to your desired website and they will quote on the amount of boards, I got a lot more as the price was relatively cheap. If I ever got a Roadster with a dead pack this would be my first way to measure each sheet and brick voltage. You could use just one board and bring each brick up to a minimum voltage and then allow the Tesla charger to take over. Or use additional boards to monitor the sheets as you charge one at a time.
Can you supply me with the part numbers for the ends? As well as what connector needed for charger end? And what chargers you suggest?The file is for the boards, after that you need to buy the ends to solder onto the board. Those ends are probably as expensive as the boards depending on your suppliers and minimum quantity’s. Remember we live in different countries so my costing may well be different to yours.
