I have a 12V compressor that pulls 25 amps and has alligator clips that connect straight to a car battery. I understand the Leaf has a current sensing system on the negative terminal and therefore I want the the negative side of the compressor cable connected to the Leaf's ground, not the negative terminal. But what mode (on, ready to drive, etc.) should the car be in to ensure I don't kill the 12V accessory battery?
