Re: VW Mild Hybrid Starter Alternator

I'm having trouble duplicating @Jack Bauer results from the start of this thread earlier, I've got savvycan at 500kbaud with a terminating 120ohm resistor across can-h can-l, 12v and gnd feeding the logic and +48v to the battery terminals, @Jack Bauer could you describe your setup more? Thanks. http...

Here's a pile of photos and somewhat un-sorted digging: https://transistor-man.com/everything_etorque.html note th...
