Take care of your rotors? 🤣🤣🤣 that's how rotors work they turn kinetic energy into HEAT.

You, my friend are mistaken. There are certain times when your body can be directly affected by 12 V. Let me give you a 9 V example take a 9 V battery and stick it to your tongue. If everything you just said is true there should be no reaction you should be able to keep that 9 V battery on thereain’t gonna happen so with that being said if you are sweating and you touch a 9 V battery yes you can get shocked. It’s not gonna be enough to do serious damage but it’ll be enough to let you know that you don’t want to do it again.

😂😂😂😂 you anderstand this wery old

Lol thanks for being the father some people didn’t have.

Voltage doesn’t kill you, current does.

Licking your fingers isn’t the same as sweating on a hot day and leaning your salt-sweaty forearm on the bear metal car engine and accidentally touching the other salt-sweaty forearm to the positive terminal of the 12v battery. Most people associate accidental electrocution deaths with being cooked, but that's not how most people die. Most die of heart fibrillation, which only takes about 0.009 Amps across the heart. This is when the heart goes out of sync and just vibrates uselessly. A defibrillator machine puts more than 0.009 Amp across the heart to clamp in from vibrating, hoping that your heart will restart in sync again. Remember your body is filled with salt water, a good conductor of electricity. It is your thin dry skin that determines the voltage pressure needed for electricity to puncture through into your salt water.

If you have a vacuum leak you’ll be running rich and viceversa also you’ll have cel on.

PRO tip: Wear eye protection if you plan to do anything that you know will cause sparks around a car battery. If it happens to have some escaped gases around it, you may get a sulphuric acid bath which could blind you if it got in your eyes! Be safe!

Can you jump right into it and do a deep dive and find the game changer, you can always reach out if you need help

For real❓How did you think❓ An eight-year-old can do this even if he didn't get homework help

Get sweaty, and you'll feel an uncomfortable tingle across your skin that is similar to an itch. That's the worst I ever got from a 12v system on a car when I was a mechanic. Now, the ignition system will make you wet yourself if you're lit up by it.

I put a 9v battery in my pocket with my keys and burned the shit out of my pocket. Total high on moment lol

Spark plugs or coils will

Literally been shocked by a car battery before while change the connection. Please for the love of all that is humanity still take precautions

Short that battery out while standing in water (rainy day), and you will never again say "This is 12 volts and can not hurt you". ... It most certainly can!

Do that with a 51.2v 100ah battery

Watch out for your wedding ring! If the charge arcs to your ring it can burn your finger so badly you'll lose it.

good details on when to change rotors

Ah okay so low voltage will eventually cut out the current thanks to ohms in our body I think

volts dont kills amps do

Alright so I have a dumb question, then. Is this still true with jumper cables? Like if i touched the ends of them would it still not affect me?

This confirms that this guy is a total wackado. Any spark=potential fire or explosion. Any real mechanic will confirm usually with a tale of a battery disappearing with a bang. This is not bad info, just an asshat way of presenting.

Instructions unclear: I'm in a spiderman movie now😂😂😂😂

I once dropped a ratchet across on a brandnew battery and it blew the full side off and threw acid everywhere DO NOT SHORT like this

What about if it makes just one click like in your video ,can I determine that it is the starting motor and not the alternator? Can I determine anything about the alternator if the car just makes one click ? I guess not but had to ask

Think 4 AAs in series for voltage.

I burned my wedding ring on my finger that way. Fun times.

What if🤨🤨🤨 heeeee gettttt..... ahh nvm

I noticed acetone like smell on the battery side of my car after it is heated up. Can you tell what it is?

Might not electrocute you but the arc will make you dang near shit yourself.

While the voltage won’t get you, the sulfuric acid in the battery will.

Instructions unclear and now I'm fighting spiderman in times square

Informative Bro.👍

Tried to jump another boat on the water and it sent a tingle head to toe. Weird feeling i dont want to feel again.

Making a spark like that on top of a car battery is very dangerous due to risk of explosion. I’m not impressed by this guy or his video.

Wouldn’t High amperes be more dangerous?

WHY DID I THINK IT COULD KILL ME

Be very careful of multiple battery setups however. I had a sergeant in the army that dropped a wrench working on the battery bank in a five ton. It flash melted the wrench and sprayed his hands and face with molten steel.

Instructions unclear. Im now a battery

What about a mechanic doing the same thing?

When slowing down in my 2004 Ford explorer XLT makes a tapping noise when decelerating what do you think might be the issue.? I don't have to apply the brakes just coming to a slower speed it starts making the tapping noise.

pretty bad situation.. learned that the hard way

This guy is a moron. That battery for starters could of blown up doing that....

Safe to wash the engine bay while battery is attached?

When stopped at a light car vibrates for a second then runs smooth

ive done that with a ratchet once

I went a ways through comments. Listen people ....never short a battery intentionally. It's a potential hydrogen bomb.filled with hydrocloric acid . If over charged it vents highly explosive gas.your charging system could do it. A battery charger could do it. I've seen 40yr machanics do it. I've seen 4 blow up in my 63years.sounds like a double barrel shotgun going off. Don't forget the acid going everywhere. Don't be stupid . follow safty rules.they are designed to eliminate sparks at the battery. This erisponsible fool might learn the hard way there are worse things than electric shock...

Thank you for the good pointers. One question I would like to ask is should the car/truck be hoisted up level to ensure all the old oil being drained out completely or would it has the same result with having the car/truck front wheels driving onto the ramps (as in your case) for accessibility. Thank you for your clarification
