Well my MIL's car battery is weak and cant start, naturally we want to jump start using our car. So being read in the internet and also even instruction manual on how to jump start a car like this pictures: When my wife saw me trying to connect the clip to the car body, she told me to connect it to the negative terminal, I told her no its connected to the car body and even show her the above picture. So I proceed then trying to start, but fail, keep cranking and the car still wont start. then my wife say try la connect to the negative terminal like she said, then I reconnect it and voila it start in one try. Then she make fun of me trying to act all smart, so I am very embarrassed. So guys, is the internet and instructions wrong? Wife is always right?

Connect to body is correct. To avoid explosion risk when correct to neg terminal.
But I think in well ventilated place, no risk of hydrogen build up, then connect to terminal. There will be a spark.

All engine bay are painted no way you can find a unpainted body , you either negative clamp on a engine it self , the aka proper is above all the negatives return to your jump start battery rather than return to your lacking power battery from my imagination lol , but no point I guess since all protect by your fuse are + if you accidentally + clamp on body I guess gg also The diagram to me look like same haha This post has been edited by zuozi: Jan 25 2020, 04:41 PM

Check the owner's manual. It may list the correct location for the ground in the jump-start section (if written) If not, the engine itself is normally the best choice as it's unpainted. Pick somewhere where the cable clamps can bite onto securely. Example for suitable point for Proton's Campro engine: The engine hoist point that's just right next to the dipstick in the picture below From my experience, if the car with the dead battery fails to start, it's just the grounding point selected is not good enough This post has been edited by TDUEnthusiast: Jan 25 2020, 04:59 PM

bad grounding to body can affect the maximum current
straight to battery in only option then

Both methods are correct . But your internet picture method(body) is less effective, more prone to failure as your experience demonstrate . I personally prefer negative to negative terminals direct method .

Thats all. Wait sometime as jump start like this will draw power from the depleted battery actually, let it charge for a while after connected.

Just connect - to - , more effective in practice.

Kesian.... you can clamp to car body, but need to be unpainted surface & MUST have good connection with the -ve terminal. If you trace the -ve leads from your car battery you will see it's connected to the car body But easier just connect to -ve terminal lah... direct power.
