Hearing the actual sound of a failing alternator was extremely helpful. Way better than simple descriptors like a "grinding noise" or a "squealing sound," etc. Thank you!
My kind of video.. no goofy ads, no sponser products, and no useless talking about stuff like the weather and what you’re doing today.. straight to the point you want to tell us.
charlie Hoss 👍😊
With the creepiest weird voice I've ever heard and real scary facial expressions🙄🙄🙄🙄👎
Great tips! Scotty Kilmer's really really decent half- brother 😂
Sounds just like scotty
That's what I thought too 😅
Sounds like Doug Dimuro who inhaled helium
@@JohnS-il1dr more like holding his nose closed
Lol, top comment. 🥇
This man must be protected at all costs
👍😂
You are the only video that professionally explained the issue I am experiencing. Thank you.
I don't have an alternator problem but I appreciate this video being so comprehensive.
It's great that you showed the bad alternator with the whining noise. Mine was making that noise for the past week along with several of the other symptoms so I had to get it replaced.
Huh, my alternator gave zero warning. Just driving along one day and it said "To whom it may concern, screw you, I quit." Just before that point, the gauge read fine and there was no battery light.
Hilarious! Happened to me too! Takes you by surprise!
Happened to me last night going down hill a mountain. Scary shit I tell you.
you should be nicer to you car lol
😂 😂 😂 😂
😂😂😂
You are a life saver!!! And money saver. I have taken my car to the dealership (after having spent several thousand dollars on transmission, and engine upgrades, etc. but kept hearing a whining sound whenever I accelerated. Each time, I was told that it wasn't anything to worry about. This was about 4 months ago. Today, when I rolled down my window and turned on the AC, the car stalled in the middle of the street. I was able to crank it again. I called AAA, they came out and used some kind of apparatus to confirm that it is the alternator. If I had known that you existed, I would have been able to inform the dealership. How can mechanics at the dealership not know it was the alternator??? I was able to find a local mechanic who replaced it and gave me a 2-year warranty. Thanks a million for your help and I can now share your knowledge regarding the s/s of an alternator going bad. You rock❤❤💯
Very informative and to the point, and rather entertaining, too. Well done!
Thank You for easily Explaining this.
My Honda Pilot started showing symptoms of slow windows and dim headlights, and the Alternator started that same whining sound, like the one in your Video. Thank you for teaching things so CLEARLY.
You are the BEST!!!
👍😊
It was what happened to us last night...
Back from Poros of Lefkada Island ..having on a.c.,music ,and lights ...we felt the dimming of lights..the turning of the lights and the car engine stopped...burning smell from the belt of the alternator...Thank you for your diagnostic description of this car pathology :)
Greetings from Greece.
👍😊
Great video! Most engine issues produce a certain burning smell and it seems like nobody adds this in their videos. Very helpful information. Thank you.
Thank you for sharing your knowledge about testing the alternator. God Bless you.
Kyu Seung 👍😊
This noise is what I'm hearing. Thank you so much for this video!
You’re welcome Shankia! 👍😊
Scotty Kilmer meets Doug DeMuro
Bobby Burnin you win🤣🤣
Be aware, newer model cars use the "smart charging system" controlled by the ecm.. a signal is sent from the battery current sensor, located on the negative terminal of the battery, to the ecm.. The ecm, then takes that information (voltage) and determines if the voltage regulator, on the alternator.. should or shouldn't be charging. Which means.. you don't see a steady 13.5 or 14 volts all the time.. Voltage varies from 12.6 volts to 16.5 volts. There is a mod u can do if the ecm isn't keeping your battery charged. These alternators have three wires, usually in a pigtail harness that connects to the alternator. One wire will read whatever voltage is passing through the battery while running.. The other two wires are from and to the ecm. If either of these wires is interrupted, the battery light will appear on your instrument cluster, and the regulator on the alternator will take over the charging responsibilities.. basically bypassing the ecm, and you'll see a more steady charge of around 14 volts.
Well thank you you just saved me a hassle of breaking down in the middle of nowhere.
Helpful video. I learned something useful about my car. This gentleman must be a good auto mechanic.Thank You
This channel has actually helped a bunch my 1990 4runner has been having trouble doing plenty of things but I started with stopping my oil leaks then air filter and next is the alternator and even my spark plugs these were all leading causes in my car having trouble accelerating normally although it is in the 2.slow gang
I'm about to finish a 1,300 page book on auto repair, and I learned something from this video. Thanks from Texas.
COMB0RICO You’re very welcome!
I'm not trying to send you click bait, but I'm just very curious if your 1,300 page book said anything about this? th-cam.com/video/rcVYfE7MQlI/w-d-xo.html
You're writing a 1300 page book on auto repair and you didn't know this basic information?
Vinny BoomBots no lol, he read the book not wrote it.
@@awog4203 He be a very long time doing the RTFM..if it 1300 pages
straight to the point, no prolonged intro. 10/10
Great video. Spoke very clear and loud so we could hear you well. You gave excellent information about the alternator.
THANKS for the Information & Testing Tip. I learned something new today.
Very Good Video.
I had a 2003 F150 for nearly 12 years. The last year I had it I saw the dreaded battery light come on. It would be on for about a minute then go off after the headlights dimmed a bit. $500 parts and labor at the Ford dealer.
Reminds me of Scotty off of crack
Lol...
@Rich Scotty DRANK!
I used to listen to Scotty,,, I stopped. He was saying things in some of his videos, he was way off. I got my car fixed by finding other videos by other mechanics. Not saying Scotty is bad, but his videos didn't help me.
But without the hand gestures, upper inflections, laughing and laughing animal thumbnails. 🤣🤣🤣🤣🤣
👎🏿👎🏾👎🏿👎🏾🇳🇬🇺🇸
Put this video on mute and it looks like he cursing you out 😂
Let me try 😊. Tu he is really good at training.
when i first saw him i thought he was Red Foreman
lol, that's what I thought. I cant watch it with sound now...
It's my first time watching any of his videos I thought maybe you were full of it but I went back and it does look like he's cussing. I never really noticed the people in the videos. 🕵️
😂😂😂😂. I thought hes smelling something stinking
Bro. You are a great character for helping and entertaining your audience.
Keep the great work
I loved it! thanks Mr. Paul!
Thanks for the help Scotty 😬
Anyone else sitting in a parking lot somewhere with a dead alternator😂
Yes
Call the junkyard
me af
Same bruh
Brent Parsons shit sucks
Love how straightforward and to the point this is
Good video! Clear presentation of the problems and what to do. Thanks and God bless!
It’s good to have mechanically inclined friends, I don’t know much about cars but I knew something wasn’t right, I thought it was my battery, took it to my friends and he identified the alternator as the problem and your warning signs are spot on, my headlights were flickering, power windows going slow, now to find an alternator, found one but it is 400 hundred kilometres away, closest city to us.
Have you considered buy one on Ebay?
proclaimliberty2000 yes, I looked on eBay, just wasn’t a hundred percent sure if it was the correct one, I found one and have it replaced now woohoo, can notice the difference in performance. Runs better than before.
Percy Nelson Great! 👍
This guy should be a news anchor
Like Indian hate news debate Chanel’s . I prefer news to be read calm.
I was looking for this comment hahaha . This guy reminds me of a news anchor as well haha
Well said Paul. . like your other video fining out which is at fault battery or alternator .when you pull the plus lead off and the car stops it's the alternator .love your videos they are old fashioned way and work great
Awesome video sir nothing bad bad it's kinda funny you sound like Scotty kilmer or a little resemblance of the way you talk and present on the video all in all keep posting
Dan dan 👍
No comparison. This man goes into detail and does things professionally. All scotty does is whine, complain, and make fun of manufacturers shortcomings.
And he takes the time to answer his comments that's the sign of a true star he never forgets his fans
Good video, but I would add couple of info bits: Never direct pressure wash to the alternator because the pulley end bearing is not sealed enough for that. The second is that when the alternator starts to fail, it also affects some fine electronics, so one can hear a whine from the radio or the ABS pressure pump starts to cycle at idle because the system thinks that the car has just been started. As the pump motor is a strong one, the problem gets worse fast. Some car tinkerers have also made the alternator seem bad by replacing the battery warning lamp with a led, as some alternators actually need that lamp to work properly. Some, like GM ones could not care less, but some do.
Some modern alternators run always hot even when the bearings are OK, as they are now rated about three times more amps than the old, physically same sized ones; the modern cars need a lot of amps just to operate and the alternators are overloaded all the time. That is why they last so short time nowadays. In some alternators replacing the voltage regulator part that also has those spring loaded bits,"brushes", that collect the electricity from the spinning rotor and wear out,can very easily be done, and if the bearings are OK, the alternator can be fixed with just pocket money.
Timo Kuusela yup a steady whine or kind of a off on bupp. Bupp. sound is a telltale sign of an alt. going out.
Man what should I do I have no pockets
My alternator died last summer. I was about 25 miles from home when the battery light came on. Lost the speedometer, temp gauges and a few other symptoms but somehow made it home. It was 23 years old so I guess I should have expected it. 500 big ones to replace.
Great work my friend. God bless you, too
Going out to test mine right now!
Very informative video thank you very much!
Dan Dotson 👍😊
Mine this morning driving when stopping at a stop sign. The lights went dim and heater fan slowed down. I had on a lot of stuff. Lights, heater, electric radiator fan pulls a lot.
Insightful. Thanks for sharing
I’ve got the whining smelling problem! Changing it tomorrow!👍🇬🇧
Thank you brother. Very informative and much better than the other vids I watched regarding this issue.
Terry David You’re welcome Terry.
I thought you might also like to watch this Terry about alternators. th-cam.com/video/rcVYfE7MQlI/w-d-xo.html
Thanks for the lesson great video
Very helpful. Great job!! Thank you!
I just had my alternator replaced today at a shop for $386 bucks and they used a meter just like what you show there, this video is actually very good on the topic of your alternator thank you for sharing.
You’re very welcome! 👍😊
Damn, that was a great price
Best video on this subject I have seen.
Great INSTRUCTION "
Thank you good shepherd
Faced tough one time on my long trip with faulty Alternator power was dripping it was raining i could not use my wipers windows un able to pull down i did not understand what to be done ultimately i kept my vehicle drive as it was with out switching off to about 80 kms to find a replacement for the battery only a temporary solutions untill i reached to my native and get into workshop for alternator repair none the less no hope what could be done i drove without power on my headlights only blinking hazardous lights tough time faced
Thanks for the time and video. My GF's 2010 Treverse's new battery is going dead after a few days. I found a .161 amp draw and have not traced it down yet. However, while driving it, I noticed that the alt voltage, starts at 14.3 but within 45 sec it starts dropping over 1-2 minutes to what the battery voltage shows when I start it, 12.4. I'm not much of a mechanic, but this seems like alt/voltage reg issues. Would you be so kind as to comment?
Thank you people making these videos
Mine, I noticed strange noise from the alternator. I rebuilt it, but didn't last longer. Thanks! :)
I have a truck that is over 17 years old with the original alternator. This is my most major concern. When will it fail? Now I know what to look for. Thanks for sharing.
I had an original alternator that was still going after 289,000 miles. This plays a BIG role in how long an alternator will last. th-cam.com/video/rcVYfE7MQlI/w-d-xo.html
When the battery light stays on ...First signs are when you start up the battery light be slower going off or flicker...Keep driving for now .The original might be better quality than some S* spares ..There always the plan of keep a good spare battery ..It could be used to limp home or to the garage if not driving by night or heavy rain or snow.
The alternator in my 26 year old Toyota Corolla just died. The mechanic was impressed it lasted so long.
Keep up the GREAT WORK,Thank you VERY MUCH.You have helped me diagnose problems in my car 💕
👍😊
Very well explained.
I just got a replacement alternator on my Camry last month. I just started to drive it and I noticed that my chargers for USB cell phone does not work anymore. My lights inside my car do not light up, and they are not bright. My windows (just like he said) are not going up and down smooth and fast like before. And this baby cost me $150.00. So my guess is to take to another station and have it tested. The amps for me are to low.
Thank you so much!
I totally agree with you buddy. We could not detect the problem of the alternator or battery by using just the multimeter. If some of the appliances of the car turn to 'dimmer' than before, that means the amperage lower than it should. About time to replace them.
John smith 👍😊
Simple, sweet and straight to the point. I like this video.
Caige Spade 👍😊
Not everyone has a Craftsman 82141 DMM.
One should always set the meter on the position corresponding to the aspect one wants to measure *BEFORE* connecting the test leads to the points being measured.
Some meters have the resistance settings "on the way to" the DC volts settings on the rotary switch.
Inadvertantly (even briefly) trying to measure resistance across the battery will result in a smoke show from the meter, which will now need to be repaired.
Doing it your way is just bad practice.
Great video 👍🏼
That last bit about the alt whining because of bad bearings isn't entirely just bad bearing if a diode shorts inside the alternator one of the poles on the starter will make a whining sound and get hot and smoke as well.
I have a 1992 Honda Accord and the grounds for the battery and everything else were connected to the body using a self tapper.... This is not adequate enough especially for the main battery ground.... Please double check these, I've sanded down the grounds on all 4 of my vehicles and now my 2 Tahoe's sit at 14.7 Volts! My Honda Accord still has a bad alternator but will be fixed soon.
Great info. Thx, 👍
Simply straight forward.
Sbu Vortex 👍😊
yep the Silverado needs a alternator, I was hooking up some subs and the amp going out the coming on when the bass hits the lights flicker, probably
I did enjoy it.
1st time anyone demonstrated a noisy fan belt. It did have some tie ins or cliches with previous vids I watched
Good tips
I remember when I had the beginning signs of an alternator failure on a 1 litre Toyota Yaris/Vitz/Echo it began to sound like somebody had dropped in a turbo under the hood. Had that 'woosh' kinda sound when going in and out of gears. Subtle but enough to raise a smile. Alternators are expensive parts but luckily for us can be had very cheaply used at breakers yards and online! Nice vid.
The Internet Thanks! The bad alternator in this video started sounding like a high winding jet engine. I hope you have a wonderful Christmas and a safe happy new year.
@@proclaimliberty2000 returning to this video 3+ years later as I've got a different car with what seems like an intermittent alternator issue! You're top of the lists and rightfully so. My car seems to be losing charge to the battery and then one by one things start turning off, then I get a faint battery light on the dash, abs warning light etc then it's ready to stall. If I give it revs it *seems* to get it back into shape - tonight I was miles from home doing delivery work when it started. Jumped it off a small battery pack I carry and after a while it seemed to be fine again, in fact I drove it for hours with no issues. I can hear a squeak from (I think) the aux belt though, which funnily enough I have booked in end of the week for checking and replacement. It squeaks a lot under load. I'm hoping it's just the belt slipping which is the issue rather than the alternator itself. We shall see!
All the best to you and yours from across the pond in the UK.
Great video! I swear I thought this was Scotty 😂 same type of explanation and words
I was driving to a job today when I noticed the battery light come on then off, suddenly the a/c, indicators,wippers, radio suddenly stopped working. It had blown the fusible link. I have never had this happen before.
Two days ago I was stopped at a red traffic light while driving my year 2000 BMW E38. Suddenly, the oil light came on and I lost amlost all power. The steering wheel was so stiff and I almost hit the car in front because the brakes were stiff too. I was wresttlig with the steering wheel trying to control the car. Luckily enough, I did manage to pull over without blocking traffic. I was sure that I did not have enough oil for some reason but when I checked the oil it seemed OK and there were no leaks under the car.
When the rescue guy arrived he asked if my battery was OK. I told him it should be fine since I replaced it about 3 months back. Anyway he just tested it and found that it was not charging at all. I was 16 miles from home. He swapped my battery for a new one in his car and put mine to charge in his van. Then he followed me home and the car drove fine. At home he put my battery back on and by that time if had a bit of charge but it was still not charging properly. We are buying a new alternator.
It's amazing how much havoc a weak battery can cause in a car. I was wondering why a dead battery would trigger an oil warning light. Turns out that the oil pressure sensor can't do its job when there is not enough power in the engine, so the warning light comes on and the car goes into limp mode.
Thank You Brother Paul!☝🏾☝🏾☝🏾🎉🎉🎉
Nichole Curry Paris 👍😊
Thank you
Easy and simple video now I know how to diagnose my problem
Archie Blevins 👍
Thanks for the information.
👍😊
Thanks for that info, this video was great
Herbert Russell 👍😊
Nice video! . Thanks . I have a Suzuki sx4 2012 crossover . When I start the engine I have 14.2 volts . But sometimes while I'm driving at 650 or 700 rpm the voltage drops to 12.4volts. .even though at night with the headlights on or off . Is that normal ?. I mean I thought it was supposed to be 14.1 or 13. Something all the time.. ? . Thanks
Thank you very much for the video. Question, today I noticed my alternator was over charging between 15-17 volts. I wasn't far from home, I turned off the car I checked the battery and it's fine at 12.6 (off) What is the possible cause for over charging?
SIGNS OF A FAILING ALTERNATOR: WHEN THE ALTERNATOR SKIPS A BEAT.
During cold winter the alternator on my sister's car started to whine very loud (still charged ok) and I was sure it was toast. Then my father sprayed some WD40 on it (not sure where, presumably near bearings) and alternator has been fine for about 3 years now and my sister drives a lot. Worth a shot before replacing it I'd say.
Might have gotten into the bearing and reconstituted the grease in the bearing to flow freely again.
belt!
@@jjjsmith2497 Unlikely - WD 40 disperses too quickly
Very good info and commentary. Ty.
chosbach411 👍
I had 3 occurrences when my 2008 Nissan Xterra lost electrical power. The first time I noticed was when I got back to the parking and couldn't start it. Completely nothing on dashboard even the SECURITY LOCK light ( car blinking icon) was not blinking which was the norm .
Then TWICE it happened as soon as I came to park at my destination. Then it either comes back by itself or it comes back by some manipulation in the battery.
Finally I got STALLED in traffic. I stopped on a red light then the gas pedal was NON-responsive. The engine was still running . The following indicator lights were illuminated: BRAKE, BATTERY, OIL, ENGINE SERVICE .
When the police came to help me bring the car to the median "island" to keep me out from traffic, the POWER STEERING was out. The brake still worked but feels a little hard.
What do you think is the problem?
The auto-shop gave me a probable bill of $2000 (2 thousand dollars).
I want to hear your probable diagnosis for comparison.
Thanks bro, Good video 👍
That's a very helpful video. Wish all the videos that I have watched were this helpful 👍🏼👍🏼
👍😊
Thank you!!
👍😊
Great ideas!
Is a early sign constantly having to jump start your when you want to use it?
I've got a battery light on my Camry dash . It's been on for about 4 years I believe. Ugh.
jon davis 4 years its long for a battery I’d replace the battery as well the alternator. Also check the terminal cables and brush any rust or debris off
Have an 09 xterra , was driving along and then limp mode , was after throttle body sensor but nothing electrical worked so I got new alt. Fixed !
My 2000 volvo s70 had a battery drain problem. Let it sit for two days, everything was fine. Let it sit 3 days and go to start it and nothing. I checked my battery and alternator. Battery was fine. Alternator was putting out 13.4 volts. Suspiciously low. Turns out it had a bad diode which was pulling juice from the battery. Got it replaced and we’re now up to 13.9 volts. Let it sit 2 weeks and it starts right up.
This video that I did pertains to your battery and alternator. Most people don't know about this.
th-cam.com/video/rcVYfE7MQlI/w-d-xo.html
Oh wow I ignored the smell and the slow window.
very good information, God bless you!
👍😊
Thanks ur video help out alot!🙂
Your video was very helpful
Just got a new alternator and it's output is 13.5 when the car is on. Is it bad? I have a 2011 Toyota Camry XLE 2.4l. Battery is brand new but at 70% due to old alternator being on a few days.
You’re a great teacher 😅
What could be the issue of a alternator with a higher voltage such as around 15 volts?
