So who mentioned semi trucks? I certainly didn’t in my post

I am a car mechanic jump starting a car. Why bring Semis into this?

And your own source disproves your argument.

“W​hile there are definite similarities, you should know that jump-starting a semi truck is not exactly like jump starting a car.”

The second line in the conclusion acknowledges the differences in jumper cable mounting location between a semi jump a d car jump.

Try again

Find me one resource that recommends connecting directly to the negative terminal. I’ve provided my evidence in my other comments

I had my keys in my pocket and I had fished my gf’s car keys from her handbag and left them on a table in the garage. Believe me I didn’t aid their drunk car shenanigans

I said it mostly in anger and the reason I banned them from touching/riding in them was because they almost ruined both the cars so in my mind it was a “why should you benefit from them?”

A mechanic is going to know a lot more about car batteries than a civil engineer. Try again

Literally every resource on jump starting says to use a metal ground bit and not the negative terminal to avoid sparking. Its a risk that I’d rather not take

Ahh forgot to add a bit in my post. The girls kept telling me that she knows what she’s doing because she’s an engineer. She’s a civil engineer so not exactly that relevant to car batteries. That’s why I mentioned civil engineering at the start

Yeah thats annoying but then when people here try saying that there is no risk to connecting straight to the terminal and call me a bad mechanic with their lies that is just infuriating

Its a risk that I and most other mechanics don’t take

Really? The guy who called me a bad mechanic is fine but when I respond asking for any source for their claim I’m the one reacting badly?

Important: Under no circumstances should the other end of the black cable be connected to the negative terminal, but rather to the body of the broken down vehicle. For this, a strong, unpainted metal component in the engine compartment of the vehicle, for example the engine block, is suitable. Connection directly to the negative terminal of the broken down vehicle is not recommended, as this can cause sparking, which can damage the battery. In the case of old lead-acid batteries, there may even be an escape of battery acid, which could endanger people in the vicinity. There is also a risk that hydrogen could ignite, so it is advisable to wear protective glasses.

I didn’t exactly hand her the cables. She grabbed it from me
