To All the fatherless sons don’t ever let the feeling of not having a father figure showing you how to do things stop you from doing it. I did for a long time confidence really low and questioning my own position in life. Pick up a project and start doing it youtube has made it so versatile to learn and it’s come to the point where I’ve learned enough to satisfy myself knowing I can teach my own son how to work on things that my father couldn’t do.
🎯🎯🎯🎯🎯💯 At this point in time it should not be really any excuse other than feeling insecure about doing something Just remember though there's always someone willing to help and/or you also got Google and RU-vid..
Just get a jump box, I got one for all 4 of my nieces for their graduation present, you never know what creep is going to be around when the their battery is dead, they did not appreciate them at first but when they had to use it when they're battery was dead or in a cold night and no one was around they were super thankful, and each has called me to say thank you, if you have an important woman in your life, buy them a jump box!!
Never put the negative clamp onto the dead batteries negative post. Clamp something metal like an engine mount Batteries give off Hydrogen Sulfide gases which can cause an explosion when you get a spark.
This so true lol like it’s not gonna happen every time but that one time and that bitch blows up in your face mannnn you gonna have some real regret sitting on your shoulders…
The batteries only create the hydrogen gas when it reaches approx a 95% charged state or it is either fast charging or overcharged. There is always a possibility of residual hydrogen gas being left over from the previous charge cycle but highly doubtful. An exploding battery is always possible but if done correctly charging them is perfectly safe. I have been a professional technician for 35 years and never seen one explode yet. Only heard stories. And I have charged countless of thousands of batteries in my time considering I was in an extreme cold weather environment (Alaska) for most of my career.(Never attempt to charge a battery with low electrolyte or a frozen battery) You are supposed to shut off the charging vehicle before starting. But I have always connected the cables red on dead batt, then red on doner battery, then found on doner, and ground on engine block of dead to bare metal.
@@BH_tradie Safety first I suppose. But then again, proper PPE should be preached as well. Because of that battery is going to explode it doesn't matter where you're standing if you're leaning under that hood to hook up that cable, your face and eyes are a victim instantly.
@@BH_tradieif that ain't the truth...! Not too long ago a 1970 Challenger came into the shop for a timing chain R&R. The service writer was going to pass it up because they didn't think we had the means to do it because it was "old technology" . I died laughing and said get that thing in My bay now. I had it done in about an hour. 😎🤣
@@BH_tradie That's my favorite game, road noise diag. My old lady hates riding with me because of it. And absolutely, the young bucks like to laugh at us ol boys up until they need to something that they can't diagnose with their scantool. Then they are amazed. And you keep up wrenchin yourself Brother. I dont think there will ever be any quit in me.
You should use the running vehicle to charge the dead battery and then turn the vehicle off and try and start the dead vehicle. If the dead vehicle has a bad diod in its alternator, it could damage the running vehicle.
If you know why the battery is dead, old battery or lights, radio, left on etc ,etc, you can just jump it, but if you're not 100% on why it'sdead, you should let it charge just to be safe.
@@CentralTexasCarSpotter Modern cars have computer modules that run on 5v and milliamps of electricity. Having 2 voltage regulators fighting can cause serious damage. Alternators put out 13-14v at dozens of amps. Its better to turn the good car off. You still get the benefit of the good car battery.
Also never connect the negative black end directly to the dead battery always connect to a solid piece of metal with a clean rust free point for the ground like an alternator bracket or something like that this will keep the battery from getting overloaded and damaging it😮 😅😊
I carry a dewalt jump starter. Literally saved my mother and fathers cars SO many times. It has tire inflator as well along with alternatoe check, one wall outlet, 4 usb ports, 2 lights and more. Its a bit expensive but its SO worth it. Trust
You need the car running for your altenator to keep your car charged, and to charge their system. This can easily take a few minutes. Especially if you're just letting the good car idle since it take higher RPMs for the alternator to push out decent amperage. Once the car that died starts you should disconnect the jumper cables. Let their alternator charge their system. So you need the good car running, but it shouldn't continue to be hooked up after a successful jump. If you're not sire check the owners manual. There are risks to certain equipment doing it this way, and frying a battery is the least of your worries if you fry something. Also make sure your not jumping a lithium battery with a standard battery. You need a smart charger or jump box with a charge controller.
@@paulcondie2520 Then buy a supercap booster. That collects the residual juice from the dying battery and jump start the car. You also can charge it from another car for 1-3 min. That really worth every penny you spend.
They have a self serving battery charging device these days. You just connect it to the flat battery only and hey presto. I have one. It's brilliant and quick starting.
I keep a lithium jump pack. Smaller than a set of jumper cables, about the same price, doesn't need a second vehicle. Though you have to actually charge it once in a while. Jumped my 4.6L F150 about 5 or 6 times before needing charged. Yes, I was procrastinating on getting a new battery.
@@reccocon3442 The one I bought said it was good up to a 6 Liter engine. Started my truck like it was a fresh battery, didn't bog down or anything. Gave one to my dad a few years back for him to use on his 2005 Jeep Commander with a big Hemi in it. He used it on his diesel Sprinter van as well. Was about the same quality. Maybe if you have a Dodge Viper or an old Italian or German car with a V10 or V12 in it, Amps would be a concern. That $30-ish one I gave my dad fired up that 5.7L hemi just fine. Maybe if there's another issue like you're trying to get something started that's been sitting for years and it's not getting fuel, you would want one of those big jumper packs. But for a drained or dead battery alone on any reasonably sized engine I've dealt with, the cheap ones work fine.
@@monicax7802doesn’t look like you received a response. I have a NOCO GB 150 they come in various sizes and $$$. Works every time. Helped numerous people and even my own vehicle when the battery was going. Wouldn’t be without it now and you don’t have to have another vehicle which is priceless.
Doesn't matter how you hook them up as a mechanics son who's father owns his own shop and worked in one for 40 years it doesn't matter ho you hook them up as long as negative is on negative and positive on positive this man out here making it more complicated then it has to be
His advice is accurate due to the risk involved with the production of hydrogen gases. But, with that being said, the do not start producing until the right conditions are met. 1) the battery reaches about a 90% charged state or 2) the battery is being fast charged or 3) there is a small chance that the gas could be still built up under you hood from the previous charge cycle (but doubtful). And those are the reason they are saying to not hook the last connection to the battery term but neither the block or strut bolt ect. Because they don't want a spark created directly over the battery. But NEVER attemt to charge a frozen or swelled battery or one that has a dry cells (low acid/electrolyte) because that can and likely will cause an explosion. In my professional 35year career as a technician I have only heard rumors of batteries exploding but I did get to see the after math once and don't want to be leaning over the hood when and if it ever does happen.
No. You always hook the black jumper cable to a grounded piece of metal. By connecting it to the black terminal on the battery you’re essentially getting the electricity to just barely and slowly go into the battery. It’s like this. By having a complete connection like that the electricity flows a lot like a small trickle out of a hose, while when you have it grounded it flows like a fully opened hose. So yes it will work by connecting both terminals but it will take way way way longer. And if the battery on the other vehicle isn’t great you can wind up running that one too low until now you’re both screwed. Lol
I had a portable car jumper box that worked great in the beginning but it seemed to lose its strength after a while even though it said it was 100% charged. Jumper cables are annoying but work much better 👌
I've had jump packs since 2015, used them multiple times to help family, friends and stranded motorist and never had a failure. In some cases the vehicle lojestics would not have permitted the use of Jumper cables.
@@alexmack956 all batteries degrade over time. That's why you test them and replace them. Cables are fine if you have some who is willing to perform a jump or even knows how to perform a jump.
First off, I wouldn’t use a cheap set of jumper cables like those!, and if I had my pick up, I would be set with a set of “slave cables, for jump starting other cars. But aside from the cables, positive to positive is correct, however, the negative to negative is asking for trouble, what should be done instead is, negative of good battery to body/ engine ground of vehicle being jumped. This removes any spark potential from being over the top of a defective battery that could be “off-gassing “ hydrogen. P.s. a good set of slave cables, has a circuit for protection of the “running vehicle “, and also a circuit protecting for reversed polarity connection, but this can also be an issue for someone who has a vintage automobile that has a positive grounding electrical system!
I was taught by my mechanic growing up that on the good battery you connect the positive cable and the negative cable to the block. On the bad battery connect the positive cable and the negative cable to the battery. That's what I was taught.
When a flat battery is connected to a charged battery, the difference in voltage can cause a spark, which can ignite any hydrogen gas given off by the batteries..so it is safe to make the final connection (ground)away from the batteries..preferably a convenient place on the vehicle..it can be clearly seen that any spark is at a safe distance from the battery
Sorry "Dad", but this WAS the way it used to be decades ago. Your method could fry the good car. With today's technology, you greatly increase cooking the very sensitive computer and other electronics. Always check the owners manual for the current and correct methods. Nowadays, tow trucks us jumper boxes or packs. If you doubt this, call AAA and ask them.
A jumper box or a battery in a car is exactly the same state of charge. It makes no difference which you use. And as long as you follow manufacturers recommendations, which haven't changed much by the way, with the exception of maybe ev ect. 35yrs doing this professionally and I have yet to hurt a charging system or battery. I own several boost packs but only for convenience. If I am in the car I will use that more times than not. The only thing that I totally agree with on here is never try to jump a frozen battery or one with one or more dry cells.
Lol most tow trucks carry jumper boxes because they’re in a tow truck 😂. They’re not driving up to cars, pulling out cables, and opening their hood 15 times a day 😂😂😂
@@midnightrider1854Oh it matters because my screen in my 2008 Acura was fried because of an idiot from a rescue service did exactly what he's doing in this video. And this was back in 2009 the car was only 6 months old.
When someone taught you how to do that, either they taught you backwards or you listened backward. You always ground both ends by connecting black first on both vehicles.
have you ever seen a battery explosion? never make your final connection to the dead battery because if it's frozen or has a dead short in it it may explode, therefore you don't want to be anywhere near it if it does. They spread acid everywhere within about a 8' radius. The live battery will not explode, so this is where you should make the final connection, as it removes you from the danger area.
@@Trapster99 there is no such thing as “overspin”. Both vehicles are equipped with a voltage regulator, so once they reach charging voltage, that’s it. The regulator backs off on the field voltage which limits the alternators output. Spin it as fast as you can, but the regulator says nope, we’re done.
@@BlainesGarage Works every time? Nope, not if it is old and the diodes are weak. Do not run both cars at the same time with the jumpers hooked up at both battery terminals. Done
@@Trapster99 When you don’t know what you’re talking about, making stuff up makes that fact most obvious to those that do. Diodes don’t “get weak”. They simply fail open or shorted. The diodes only job is to rectify the current being generated from A/C to D/C. Failing either way has the same result - less charging potential.
You should not have the car with the charged battery started. It’s okay to run that car to help build charge in the dead battery. But when you are starting the car with the dead battery then the car with the full battery should be turned off. Otherwise you could cause a power surge that will fry the alternator or other electronics in either vehicle. Make sure the jumper car is turned off when you attempt to start the vehicle with the dead battery. You are simply borrowing power from the other vehicle to help start the car. Also note: You should always hook up the ground (black cable) first and remove it last.
I prefer to hook the good battery up first then clank the two clamps together so sparks fly just to make sure its working right. This is how my drunk dad did it in the garage and his dad taught him and how i will teach my kid.
Thats not safe on new vehicles. You must first try to ground the dead car to engine block or chassy or you might burn your computer. Old men know about old cars but not new cars.
Gray fox is correct, if the ground cable is connected to a ground on the vehicle when the attempt to start the vehicle the voltage will travel through the starter, not the battery, no chance of battery explosion.
And, for all you introverts, there's a gizmo at the parts store that is basically a battery with cables on it. It's small and light and you don't have to talk to anyone. You can just jump your own battery. And they generally have USB ports now days so you can charge devices also. Just remember to recharge the thing when you ha e to use it!
Nope, jumper cables require a second car to help. Get a good jump box with a tire inflator. You can also use them for emergency power to charge devices and most come with a light. It's quicker and doesn't require a good Samaritan to help.
Never put a nagative terminal on the dead battery. Always put it on bare metal part such as engine hoist points. Also never run both engine at the same time as the alternators will interact against one another.
If the dead car won't start, disconnect one of it's cables and connect the jumper cable to the disconnected cable. A bad battery will often suck up all the power from the good battery.
Never connect negative side clamp of the jumper cable to negative terminal of the dead battery. Always connect negative clamp to a good solid metal ground. Because if dead battery has an internal short you will definitely fry your good battery. Grandpa must have slept through electricity class in school and knows nothing about electron flow theory.
Looks like a ritual lol. As electronics engineer i can tell that the connection order doesnt matter. But if you connect to car body then this will add some mohms to the circuit.
I guess I’m fortunate.. I had a father that taught me how to drive, how to fix our car, how to measure and cut wood, how to drive a nail how a screwdriver and a wrench works… I feel sorry for the people that didn’t have that… a guy I know he didn’t have a dad and his toolbox has a butter knife, some yarn and a roll of tape in it.. and one of those plastic hammers that you get when you’re a kid
Battery to battery will sure fire start, but mechanics tell me it is bad and the reason you connect to engine ground is to prevent battery explosion on dead car. Plus remove cables immediately to prevent alternators fighting each car with over charging
The reason for connecting one to the frame of the car instead of the battery is because batteries can have an explosive gas around them, and when you place the last clip a spark is produced. Sparks and explosive gasses are not good things to have in front of your face at the same time.
Never have donor car running when trying to jump dead car unless all the cars were made in 90s. Newer cars have do many electronic modules that you ll fry them. Lots of $$$ to replace. The advice to connect both batteries and start good battery car and run it for 5-10 mins is good. Then shut down the donor car and just start the dead car. Also as many people pointed out it is way safer to connect dead battery negative black terminal to car body instead to battery terminal
Supposed to connect the black (ground) to a metal piece instead of the battery. This eliminates the rare chance of explosion due to gases emitted by the battery.
Couple of guys set their cars up to jump start one of the them. They don't have any cables. They ask around if anybody had cables. Nobody has a set. What they didn't realize is that they were in the parking lot of Walmart. They could've just walked in and bought a set so they could be done and ready for the next time. I don't know how long they set in the parking lot asking people for cables.
Agree negative should never go on the dead Carterton, if it's truly dead it can act like a giant resistor & absorb all the current, so dead car won't start......
Perhaps car manufacturers should put a designated ground post for jumping. It would make it simpler. Some vehicles there is no good place to clamp to that is accessible, not painted, and away from moving parts.
Everything this guy said was right except for one thing… if you want to avoid destroying your alternator from the good battery make sure you turn it off before attempting to crank over the car with a bad battery that will avoid destroying your alternator
I jump a battery once a decade any more and referenced this video rl quick just to make sure I remembered correctly. Thx for the vid! Love, another dad who just had to walk his son through his first jump.
Good way to fry a computer. Turn off helper car before cranking. Also most new cars have jump points labeled that are not on the battery. Just buy a jump pack to carry in the trunk and leave the cables in the attic.
I learnt this from a different video which didn’t have so many different subtitles at different positions in the frame, with different font sizes and colours. THAT was helpful !!
the reason for making the ground connection to a ground such as engine block is to prevent a spark being created on to other battery because a spark at a battery may create a fire or explosion hazard from the venting battery gasses
How about when you disconnect the ground from your good battery, for a repair, then reconnect after? There is always a little spark especially with newer cars because they always draw some power.
You can go to the good battery and hook up the red then black, go to the bad battery and hook up the red then black. Same difference, less back and forth.
no. you just f up both cars. A always find a good bolt to connect the ground. B let the good battery charge dead battery. after some time, shut off charging car, disconnect cables then start dead car
Did everything in this exact order , but it wasn’t working. Battery was just barely on. But i came to the comments and then saw people saying don’t connect negative to bad battery connect it to a metal piece to ground it and then my car turned on instantly.
Jump starter, jump cables and fix a flat. I carry jump starter and fox flat on my Harley’s and a jump cable extra in my car. Fox flat is sure nice when you come out ready to go but your tire needs work. Or it’s raining , or emergency. I jumped a V-8 with my jump starter.. mower, motorcycles. I never get stuck.. unless the worst happens.. on trips I carry an extra battery and alternator, belts, fuses..real spare tire.
I swear he looks just like one of my customers when I was a kid.. I used to mow lawns back then.. everybody loved me cuz I had a push mower.. I cut your lawn early morning without any noise except The sound of blades cutting Grass.. people rather hear that than a loud motor that piss off their neighbors 😂
Sounds good, except for when you run both cars at the same time. While they're hooked together on modern cars. You don't wanna do that it'll mess up the electronic
I’ve been a merc Benz tech for 42 years and jumping vehicles is not what it used to be! These vehicles now deal with minimal voltages and amperage’s and all it takes is one little blue spark to blow something in a control unit so just be very careful when jumping newer vehicles
With cable you need another car with a kind driver to connect to his battery if ever they will stop to help you. I bought rechargeable portable battery to all my cars from Costco. I was able to start my car when needed. You won't regret if you have one.
Scotty Kilmer says you should never have two cars connected via jumper cables running at the same time, because they can damage electronics in the vehicle, as both alternators are working against each other.
Always remember to make sure your red terminals are both positive too. Dont just go with color. Wife had a truck and some dude had a red pig tail on the negative and no mark for the positive.
There is no need to shout, chief. Computers and phones have volume control. Just because you can't see us doesn't mean we're 100 yards around the corner 😊
please always connect cable by cable and do not clamp the negative terminal, only use the positive terminal of the dead battery to provide current to the battery and let the dead battery ground itself otherwise you are providing an earth to the healthy battery which also has to ground its own current. Furthermore to this, you still obviously have to earth the live battery to the dead vehicle so that the current can return through the dead battery and earth on the dead vehicle's body or go through the positive cable.
Epsons salt 1/2 cup & 1/2 cup distilled water. . Mix well . Battery will clean its plates for better charging . Battery will last longer too . Werx . If you take the neg battery turminal off and the car shuts off . Your altenator is not charging check all connections first before the swap
Hey grandad, maybe you should roll with the times and buy a decent jump pack? Probably about the same price as a good jump leads and takes up way less space. I left mine for over a year in the car and it had plent of power to jump my van.
If you do that with a new car you can fry internal components. Have to leave the good battery car off so it's only providing the battery power. That was it doesn't surge the high power into the bad system.
Never leave both cars running at the same time while hooked up after starting. Turn the good battery car OFF, then start the dead car. Ground negative to frame. NOT on the dead battery terminal..
Also you need two sets. Copper wires are so impure these days. High resistance. Connect two sets in parallel otherwise you won't get enough power to start and think something else is wrong.
