You can definitely tell when someone knows what they’re talking about and definitely the one that when hands on, will do a quality job just by how they explain things if you know you know
This is a highly informative video and even though I have experience, I still love to see such common sense clips just to remind and revise on the skills that I have. This is what makes UTube my favourite of the internet. Once again, many thanks......from Latvia.
It's just due to the fact that if your wrench happens to touch the body or engine (ground), nothing will happen if you are disconnecting or reconnecting the ground (-) wire. In this case, you are touching together 2-negative terminals. There is no "electrical pressure" (voltage) difference so there will be no current flow. On the other hand, if you disconnect the positive first, and your wrench touches ground, now you have completedd a + to a - and current will flow. Burned hand or Batt Kaboom

I took my drained battery to AutoZone they said I needed a new battery and could not recharged it becuase they said the battery was no good bad cell. I had left the lights on. So I had to buy a charger and charged it myself. That was two years ago the battery is still working. Bad cell and all.
the positive cable holds a charge....power..... you could errantly make contact with the engine ground producing electricity......in the reverse..putting it on first...to be safe for it possible that while moving things around you can accidentally touch it to a ground source
Does anyone know where I can take my battery for a free charge and test? I live in san mate ca? or how would I find a place that offers such services? I am having such problems right now with my car and this vid really has helped a lot thanks autozone.
My car battery is ok. Alternator is ok when car starts checklight turned off. But battery is not charging. What problem there will be? Is this fuse problem?
Hello, although I have replaced the alternator & battery, I still have a message that says: check charging system, & some times the battery drains only when the car is off for over night, could it be a wiring power supply problem or what may be the cause, thanks
regarding the test of removing one cable once the car is running, is it for any specific cable? because I remember doing this with the - cable was the way to test alternator
You can check your amperage before and then pull the radio fuse and if the amperage goes up after pulling the fuse, you know that your radio is your problem.
I have an 01 Camry,4cyl, started up,run good,alternator output charge 14.7,after about 5 to 10 minutes,car started to shake. I checked the output charging voltage,12.5 to 13 volts. So I unplug the connector at the back of the alternator, I checked each one for voltage,I found all three wires,have 12 volts. It should be only one wire that has 12 volts,right? The other two, are signal and ground,right? Can you explain ? Thanks
My 2002 gmc sierra 5.3 would start but in way like if its dying like not fully like it would wanna turn off so i have to turn it off and wait acouple of seconds then i starts properly? Can u make a video or any ideas....
Hello mate, I see 14.7V directly from alternator but 13.4V at battery on idle. When I connect + of multimeter to + of battery and - of multimeter to the + bracket of alternator I see -1.5V which confirms the appr. diff between 14.7 and 13.4. Where is the problem? I sandpapered all terminals. And the + cable harness loom between alternator and battery is quite well isolated and very hard to reach as it passes between exhaust manifold and engine. Your help will be appreaciated.
I get a message from the computer "no fuse" and the alternator doesn't charge. Measured at the battery. But it's so hidden under hoses and stuff that I have to disassemble half of the accesories to get a reading of the ampermeter. If there is a relay or fuse for that how must it be labeled ?!
ok,BIG question, my battery is at 12.8,the cold cranking amps r supposed to be 650,but is registering at560 ,DOES this have to do with anything??I replaced the alternator & it starts fine "more power than before "but now, it starts, but hesitates like it don't want to,but it does for now.any info would be greatly appreciated. ty.
I owned a Kia Avella Hatchback. I have a problem with the AC. When I start the engine then turn on the AC the engine will shuts off. But when I'm driving I can turn it on but it feels like it takes a lot of power from the engine.
My car has a problem to start. Then I wait a few minutes and I try again and it does starts, but then it turns off on the road again. The alternator is new and tbe battery as well.
So i bought and replaced my battery and alternator a few months ago car been running fine until “check charging system” what else could be draining my battery? I checked my cables/wires on battery and alternator.
All of my lighting (headlights, tale lights, dash lights, radio etc) pulse or flicker when the vehicle is running. I read somewhere that that is a dirty alternator? Anyone know what causes it?
hi sir i have a ford focus 1.8 tddi diesel engine car. the problem is that the an alternator is work or not i am very confused. reason of why at the day time when i drive my car the battery of warning sign is not appear but while i drive at night the battery warning sign is appear when turn on the headlight. however, i felt something is burning smell in the engine. what is the solution sir?
My astro van won't start at all it is not making a sound will not jump start Barry called seem to be connected properly what could be the problem? Am my lights and radio wields fine
Very well explained. But my head is spining. Finding a genuine with good knowledge mechanic in the UK is the problem. They rob you as well. Mine is struggling to start. I have to drive everyday to keep the battery to hold charge. Battery is 1 year old but its Lion brand. Lot of people had issue with this battery. I am bit worried it could be something else
Hi...when I turn on my head lights,radio etc. My car it shuts down. Even if I press on the gas. I checked the alternator with meter and its at 14.5 volts and battery is at 13.5 volts. Any suggestions?
Mrinfoone i have a 1995 toyota camry. the alternator died on the expressway and after it got towed i changed the alternator and battery. now the dashboard lights don't work and the odometer shows no rpms or anything. soes anyone know what I should do?
I own a Nissan Maxima 04 with a new Optima Yellow Top battery. With the car off it reads 12.6v, with the car on it reads 14.1v. Here´s the thing, once I start driving, like in a busy road where I need to stop every two seconds the voltage starts to drop ´till 12.3 when the driving voltage was 13.8. I don´t know if its because the heat but it starts to decrease from 13.8 ´till 12.3 or lower. It only goes up if I hit the road again (with speed) and it won´t go up to 13.8, more like 12.8v. So does the alternator works or is starting to fail?
+Sir Jay I still don't know. Took the car to check the alternator and its fine. Seems like it happens on hot days because with this weather is just fine. I'll keep searching for an answer.
LOV2XRL8RL did autozone say the alternator was fine? or did you take it to another shop? I charged my battery up yesterday and after a charge and the car running my portable meter reader shows it's at about 12.59V when running....
+Sir Jay I went to AdvanceAutoparts. The thing is when I start up the car it reads 14.1-14.3 While driving it goes 13.6 -13.8 and in a stop it goes 12.6 - 12.8 (idle)
LOV2XRL8RL mine doesn't get to 14v. highest is 13v... i have a charger and will recharge it for few weeks to study it as i diagnose it. i'll go too auto zone again and see what they'll say. las time i was there they said it was too low for them to pinpoint the problem. also the positive was a little lose but tightening it didn't really make a difference..
i just purchased dodge neon 2003, and i drive with it 4 km and engine stopped losed all the charge, i get a fully battery from my brother and i drove it home, so today i changed the alternator, but it wasnt the problem, i cleaned everthing that on the connections, but still no charging, i looked at the starter cables one of the cables broked and it was the positive that came from the alternator, i fix it, and now working good, so when u have charging problem, first check the battery and the alternator, but how to check it put dead battery and boost it and remove the boost and see if the engine going to shut off or no in about 30 to 50 sc, if engine start to go off u should check the alternator, so to check the alternator u should get a cable and connect it to the alternator and then start the engine and check the volt if high u have cables problem like me, so all u can do is following the cable which is the positive that coming from the alternator to the starter or to the battery, and change it, thats all.
Finally a professional clear explanation of vehicular maintenance
This video was way more helpful then any autozone or autozone employee Ive ever made contact with. Maybe should use this in a training course
"you should always wear proper eye protection..." Proceeds to take off safety glasses and they are never seen again during the video 🤣
Very well presented and thank you AutoZone and the man who presented this.

I was impressed by this video. He helped me find my problem in my expedition. Gave simple instructions on how to go about it.
Glad to hear it helped. Happy driving, Vanessa!
What was wrong with urs? What was it doing? Have an 03 expedition im having trouble with.
A very informative video by a true professional. Thanks for the tips
Super video. Straight to the point and very helpful. Thanks!

@Bryan Davian Thanks, I signed up and it seems like a nice service :D I appreciate it!
@Jasiah Maverick Glad I could help xD
Good advice that you sound like someone from classic films 🎥
Very good explanation of starting and charging system and what to look for.( excellent)
this video was very helpful, thank you AutoZone!
Wow, after listening to him for 5 min I'm ready to junk my truck
I am using your voice at sleeping time 👍
Soothing....lol
Thank you so much this has helped me out a lot my car is making that noise so now I know it's my battery God bless you
i like tha way you give info.. no drama, just info. Thanks ^^
Don’t forget checking your blinker fluid guys... very important.

thank you for recording, we really want more educational videos like this.
Apparently AutoZone shops at Harbor Freight Tools! He's using one of their CHEAP & FREE multi-testers' to check voltage, etc.
+MyEyesBled I have spent months researching into fixing a car battery and discovered an awesome website at Magic Mender Wizard (check it out on google)
What's your point?
old but still relevant, they should do update video
I took my drained battery to AutoZone they said I needed a new battery and could not recharged it becuase they said the battery was no good bad cell. I had left the lights on. So I had to buy a charger and charged it myself. That was two years ago the battery is still working. Bad cell and all.
That's because they either had a new guy who knew jack chit, or because sales were low and they wanted to sell you a battery!
I love your video. Professional explanation. Thanks
Yes I got you very professional explanation.. Thanks I love it! Because I have a ford escape with such problems
the positive cable holds a charge....power..... you could errantly make contact with the engine ground producing electricity......in the reverse..putting it on first...to be safe for it possible that while moving things around you can accidentally touch it to a ground source

Lol, you forgot voltage regulator and ECM problems. My problem is that the ECM controls voltage and either needs flashed or replaced!
Very awesome video ... can u do more on electrical as well
thank you~~ lots of helpful information:)
These videos always seem to be working on GM vehicles.

My car battery is ok. Alternator is ok when car starts checklight turned off. But battery is not charging. What problem there will be? Is this fuse problem?
i got the same problem with my toyota avalon?
My ol man truck is not staying charge
Saddam Hussain my 97 Ford Windstar is doing the same thing?
Hello, although I have replaced the alternator & battery, I still have a message that says: check charging system, & some times the battery drains only when the car is off for over night, could it be a wiring power supply problem or what may be the cause, thanks
Very helpful video. Thank you.
5:30 repair anything suspicious. then start replacing stuff. AZ will happily sell it to you.
regarding the test of removing one cable once the car is running, is it for any specific cable? because I remember doing this with the - cable was the way to test alternator
Well said...thank u for ur info
at 5:14 you mention after market radios and/or excessive cables causing burden on system. If this is the case, how will I know and what do I do?
You can check your amperage before and then pull the radio fuse and if the amperage goes up after pulling the fuse, you know that your radio is your problem.
Great job! To the point and right on. Thank you Sir.😉
We’re happy that you’re happy. If you ever need anything else, we’re here for you.
great solution
Glad we could help you out. Happy driving!

Hello mate, I see 14.7V directly from alternator but 13.4V at battery on idle.

I get a message from the computer "no fuse" and the alternator doesn't charge. Measured at the battery. But it's so hidden under hoses and stuff that I have to disassemble half of the accesories to get a reading of the ampermeter. If there is a relay or fuse for that how must it be labeled ?!
the only difference is this guy actuality knows how to fix a situation ahahahha.
This video is very important,but add another systems such as suspension,steering,braking,cooling.....systems.
Thanx for your valuable advices
Good work !
Very useful channel

Any job there for automobile electrician,thanks
then once you have replaced the alternator with an autozone one then you will have the pleasure of changing it again in a month
Never had to replace a Duralast aka Autozone alternator or starter that I've installed on my own or my parent's vehicles before.
What a great video Thanks!

How to check the AC current off the stater in the car
nice information sar
Why should the negative cable be disconnected first and reconnected the negative cable last?
if not bub you could be barbecued by power from positive passing thru you to ground(negative) / wise up bub and stay alive!
I start the key in it won’t turn on but the lights come on
Its not a motor guy, you are older like me. You should know this!
