How to jump start a car - expert guidance from the RAC 

thank you i thought this video wasn't quite right and i couldn't quite put my finger on it thank you

This video is another reason not to join the RAC. It’s almost like they want you to call them out. Poor advice, is this an actor?

Cheers from Scotland. I had a suspicion the RAC guy was wrong.

Because of quarantine I haven't started my car and now got a flat battery

I l6 the fact that you blew me 6 and I was k. 7kk m. I k I 76 the m mn jm 6l8l

I would have 100% made this mistake as well

It's almost like they want you to damage your car further!

You are correct.

Needs an earth

I was wondering this myself as I had to jump start my car the other day and I used the method I had in my head ( (+) of the bad to (+) of the good, (-) of the good to the (-) of the bad). But even my car manual says the last step, (-) of the bad, should go onto engine mount or similar. I found out it's because some batteries produces flammable fumes which could get ignited by the spark. Idea is to avoid this spark around battery. I have two issues with this though: 1) I always see /small/ spark(s) when I connect or reattach the ground of a battery on my car. Either because I installed a new one or I had previously disconnected ground before I worked on a car. I can't avoid those sparks, what then? 2) The last step is dangerous as the ground is a hot wire, I can do a damage if I'm not careful while looking for a spot where to put it (if I can't use (-) of a bad battery). It's good idea to find that spot before using cables then. Newer cars have dedicated places in engine bay where wires can be connected from/to (BMW that jump started me had those).

Mine would not start (-) to body. It would only start (-) to (-). Connecting to the body is only when no terminal is available?

disconnect the jump leads in the exact opposite way you put them on. earth > neutral > positive > positive

I attached it to the engine block. It worked.

@@WythenshawePhil what's an engine block? Like this is not a video for a real beginner like me

@@alaskafiedlermaybe don’t try it then? 😂

@@scottb4993 did I ask for your opinion??

any unpainted metal under the hood, the engine block or part of the frame.

Not really, the explanation is wrong, you first need to connect the red cable to the donor car's battery +/positive terminal, then the opposite end of the same cable to the flat car's battery +/positive terminal, THEN you do the same with the black cable using the -/negative terminals, I hope you didn't follow this video, also read the other comments

He did ground the black on the dead batt car

Always connect positive first as if you do it the other way it can cause sparking when you conect the positive.

no. Its too weak to handle the current. The current can go up to 100A or even higher for a short amount of time while starting. speaker wire will probably get very hot and smoke and might burn + For this to work, you need to remove isolation from the end, and then theres a big risk for a short. This is very very dangerous.

Even "thin" jump leads are the same size as thin WELDING leads, used on small, low power welding sets. Your better off just buying a good set of jump leads really, their not all that expensive at the end of the day and will do the job properly. If you have a set of speakers leads big enough (thick enough) to use as jump leads, you've already spent more on them than purpose made jump leads anyway.

love you too

@@himegsweg love you more

That's probably because you didn't have a suitable grounding point. The whole reason that you are supposed to use a grounding point and not the negative terminal, is because when you remove the negative lead you can get a spark, and you don't want a spark to be anywhere near the battery!

Elaborate?

Good one Stan Laurel

The video's only 2 minutes long...

@@justCommando exactly what i was thinking! Lol

Where's the fun in that? I got greeted by an "OYYY!" and now i remember that some weirdos call their hood a "bonnet" 🤣😁👌

It would probably take 1:15 to to scroll down to this shit comment

Another point: Other videos advise NOT connecting the negative cable to the negative terminal of the flat battery. Instead, it should be connected to a bare metal part of the car away from the battery, which may produce hydrogen, which could cause an explosion. The other reason given is that connecting the cable to the negative terminal may affect the car's battery monitoring system.

@@johnlyon9330 Might want to watch the video again, it shows connecting the jump leads on the flat battery to the engine/body earth not the battery terminal itself.

Why are you here then lmao

Don’t have sex with it either

Could I just caress it and talk dirty to it

also good idea to connect a 12v power supply to the terminals so you dont have to reset items after such as radio pin, manyautosltd.com helped me a lot for fixing and replacing my car battery highly recommended
