Jump starting

Read this on fb. Did 400 dollars damage. Can't believe this unless reversed polarity when hooking jumper cables up. Is this true?
The price of being a Good Samaritan. Got asked for a jump start at WalMart and, being a good guy, obliged them. All the lights on my dash lit up and the car got really sluggish after the start. Turns out jumping newer model cars shorts the sensors in parts of the motor. Several mechanics at AutoZone as well as my mechanics said NEVER jump start another car. It creates chaos in the electrical parts of cars with check engine lights and can short out any number of sensors. Guess I got “lucky” I only shorted out two. Maybe I’ll save some friends from the same experience. I had no idea!

What did he have to replace? I'll just say it hasn't happened to me yet   or anyone I know for that matter... 

Thanks for the reply. I don't know. I have a noco boost pack and never had a problem with newer vehicles. Just seen post and wondered if anyone else experienced any problems.

 

Has to be fake.

Hasn't happened to me, either? :silly: I jump start stuff all the time.

I find that most cars suffer more from the low battery voltage condition than from the jump start itself. If you didn't understand what was going on, you might associate the symptoms with the jump, instead of the low voltage.

Sounds like BS, to me. I would bet money that someone hooked the cables up backwards. I have seen that a few times. Especially, from a guy that considers the employees at Autozone to be "Mechanics".


 

Never experienced this personally, just hear'say...

I remembered a discussion a couple of years ago:

And this is a quite interesting reading on transients in an automotive environment:
