12V connector behind nosecone

[kirkbauer]

I recently found the 12v connector behind the nosecone of my 2015 Model S P85D. But I read online that there is a 50-amp fuse attached to that, and if so that would make it unsuitable to jump another car (I didn't want to try for fear of blowing said fuse).

If this is accurate, what is the terminal there for? To "jump start" my Model S if the 12V battery is completely dead? Does it work? In other words once the car is started will it keep running once "jump-started"?

This is to supply power to a dead 12V battery in order to power up the Main Control Unit so that you can take it out of Park and activate Tow mode. It is not for jump starting other cars.

The battery is too small and not designed to jump another car. It's a deep cycle battery, not meant for high cold cranking amps.
