I'm just curious if anyone has attempted jumping another vehicle using their Model S. I kinda thought it would be ok so I jumped my lawnmower which always has a dead battery every week (I'm lazy and it really needs a new battery). Usually I jump it from my wife's car but she was out. I didn't know if the Model S should be on in any way shape or form. I just popped out the nose cone and hooked it up and jumped. But I didn't have any problem. It jumped right away. In fact, I'd say it jumped much quicker than any other week that I jumped it with my wife's ford flex. Anyone else try this? At least this was for a lawnmower battery which is smaller than a car's battery. I guess what I would be afraid is draining the 12V completely on the MS and then having to jump that lol. I don't even know if that is possible to drain the 12V bc wouldn't the MS keep it fully charged from the main battery pack?
