12 Li-ion battery dead [car bought at auction]

[LucasZ]

I bought the car from the auction that was not drivable ( blown pyro fuse and airbags ) that's the reason probably why 12v li-ion battery is drained. I replaced profuse and with jump start connected car can turn on the screen , update software and I can hear CLICK on the high voltage battery. Problem is that windows are roll down and I can't move them any direction , and car is not showing gears so I can't move the car also. Any help will be appreciated as im new to this stuff and trying to learn and enjoy my repair before I call Tesla this is learning project.

You need to replace the vcfront and most likely the LV battery then do software update while powering the car with a 13.5V power supply that is capable of providing 50A. PM me with any questions.

It will sound stupid but I can't find the way how to PM anyone here.
SO I saw somewhere that you can reset vcfront ( I guess service menu ) also I was wondering if is not easier to repair the car and call Tesla to switch battery ( car is with clean title and still under warranty )

No not the battery. The CAR needs up to 50A to power all low voltage components.

And for any power supply, the amp rating is the max that the charger can handle. Actual current will depend on the device that is drawing it.

Cool, thanks. I just ordered a 120 amp charger.

If anyone reading this needs a vcfront, I have a new one that I bought from Tesla that I didn't end up needing that I can sell for $350 shipped.
