Model X to jump start an ICE pickup truck

[TechVP]

Non conventional question for the forum...

Seeking advising using a Model X to jump start another vehicle.

Using the B+ and ground marked under the frunk of a Model X, what would be the ramifications to jump start a cold, low voltage 12v battery on an ICE pickup truck?

Let's suppose both are connected via jumper cables and the truck starts.

What issues might come of the truck alternator now introduced into the 12V system on the X?

Would X be at risk?
Fuse blowout risk?
X charging system risk?

Other??

From all i have read the 12v in our cars is very small.the battery is the size of mower. Zero amps to go. Its just for dashboard.
I dont see it putting out any power to jump a ICE car.
I think you would blow up the system , trying to suck out all the amps needed to jump.
Buy a jump box.

Starter boxes aren't very expensive these days.

I guess if I didn't have any alternatives, I'd use the X to charge the truck's battery, and disconnect before cranking the truck. That way, the X won't be exposed to the voltage drop, or whatever spikes the alternator produces.

I don't actually know how well the X would cope with them, but I wouldn't want to find out the hard way.

Depends on the truck. but probably no significant issues.
By dependent on the truck, I mean a newer version vehicle in good repair, just a dead battery. Most newer vehicle need very little starting current, that's why you see the small battery packs now functioning as car starters.

Now if you are talking a F-350 diesel, that may be a different story.

I don't think it is designed to do that. The ramification could be a stranded Model X AND truck. How about a small jumper box like this one.

For $70 or so you can get one for big engines, like this one. https://www.amazon.com/gp/product/B...6212-545f-932e-e71ea04f0d93&pf_rd_i=318336011

I would not recommend such an endeavor.

Hi All. Thanks for all of your contributions. I bet many had wondered... but dare not ask.
Glad I hadn't done this in a pinch... for Murphy would certainly be having his last laugh.
