as a career tech, (power plant and semiconductor) you just don't get this kind of knowledge and communication from a technician very often. Fantastic video Ratchets and Wrenches! can't imagine where those dislikes came from
Doesn't matter who you are or what you say there's always a troll that will disagree just to disagree.
Great explanation
Thank you for your input. Your video was very educational and you explained everything so clearly. I appreciate that you took the time to make this video and teach some of us how we trouble shoot alternator problems. Thanks again
The best explanation of how a alternator and charge system ever. Easy no BS everyday explanation. Well done

I agree
Very informative thank you for sharing do have a blessed day
Yes you have the best class I've ever seen on CZcams! 35 year diesel mechanic here
WOW! As a engineer, this is a superb tutorial for the layman / armature. Really NICE job!!
Layman?! For anyone seeking wisdom without Attitude.
@Bruce Lee If you feel inferior in the presence of an engineer then that's your problem - not his. You need to work on your self esteem issues.
How did you become an engineer?
Sometimes those technician will fix the problem that made by shitty enggineer🤭
@@michael-xe7rz armature and amateur sound similar, so armature was an acceptable attempt at a pun.
Most informative and precise auto repair video I have ever watched! Thank You!
Your the best at explaining the subject at hand and backing that up with great editing!
Clearly Amazing .. I have watched so many videos on this .. Yours makes so much sense. I never once had to stop and rewind so I could listen again and again. ThankYou Crystal clear explanation!4
Excellent video on how alternators work, troubleshooting and testing. Know you have helped many people work on their own vehicle's. I am currently working on an older vehicle for my grandson. Many thanks.
The symbol you pointed out on the Ford diagram is actually a capacitor. It's there to absorb voltage spikes mainly to prevent radio interference and to keep the voltage output steady. This is an excellent video--very informative. Keep up the good work!

Joseph Wash .....yea
Super job! U covered all the bases. One tiny thing I might add is the one way clutch that a lot of new alternators have. A Honda Fit gave me a fit. It was slipping and not charging when heavily loaded. Sitting at idle I had 14 volts. When the fans kicked on, it wouldn't keep up. Once again, great teaching!!
could internal regulator be controlled by the computer on car? Because I replaced alternator and battery but from battery terminal i only get 12.5 if i try to disconnect the battery engine turns off.
I missed a lecture on this at school but your video helped me for the test I have tomorrow.
Thank you.
Well Done!!!!!!! I’ve been working on my own vehicles for 40 years and I still learned a lot in this video.
I like the informative demonstration here! Ive worked with alts (inside them) for quite a while and this was great.
Great video and explanation of how an alternator works! Great job with the diagram and taking the alternator apart to show how all of the parts work together!
Excellent video: thorough and well communicated. Thanks for educating and helping so many people!
2 Days from my 4th Year Heavy Duty Red seal Exam so brushing up on things - Great Video!!
Many thanks for the explanation, clear and to the point as the other vids!
Best video I've seen so far on testing alternator/regulator/battery! You made it very easy to understand. Thanks!
I don't know if you'll see my comment or not, but I'd like to express my gratitude for your effort. The information provided was extremely helpful, and you delved into the subject in a detailed manner.
Thank you for your hard work. The information was very beneficial, and you went into the topic in-depth.
Very thorough and understandable explanation, right down to the details such as where to set your multimeter dial, how the alternator and voltage regulator work, etc. I already knew a lot of this stuff, but your video is an excellent refresher. Plus, I gained quite a bit of knew knowledge from the details you presented. Having the disassembled alternator was an excellent teaching tool. And, the camera work was well done. Keep up the good work - I look forward to viewing more or your instructional videos! Thank you!
😅m😅mm😅😅mm😅me my omdear loo😅😅po😅😅
You are awesome. Man, I have been looking for a thorough explanation of how to troubleshoot my charging system, and this video is, by far, the best tutorial I have found. Thank you.
Not only you are a professional, but and excellent instructor, your Service Videos are about the best I have seen. Thanks . Marco.
Wonderfully thorough video and answered my question about the two terminals on the back of the alternator. I knew one was + battery voltage to the stator and the other was to the gauge.
Great educational & informative video! Even my kids would understand this! You're an excellent teacher, well done!
Awesome video. Very informative. Extremely helpful. Great explanation of working your way throughout the entire charging cycle to make clear what makes it work. Before I could only say motor spins alternator which charges the battery. I know there are a lot of wiring diagrams out there. At least now, I actually can make sense of one too. Super neat knowing what I've learned right now. I'm in the process of installing a car stereo system with multiple amplifiers and batteries. I've seen other car audio youtubers show all the "where's" to make connections but leave out the "why's" or "how" it works. I just want to learn more now. Thank you so much brother.
Wow, I 49 years of life I never thought anyone could teach me this material, bro u did an amazing job of explaining this, thank u!
Man!! that was the best video about alternators. You have a perfect clear knowledge about what you are talking about.
nevertheless all other are very good as well.
Thanks a lot
Wow, that was a really thorough explanation. Thank you!
Having issues with my dual battery 7.3 idi diesel charging system and I watched a ton of other videos that got me started but nothing worked and left me confused. Your explanation is much more complete and I now feel confident to give it another go tomorrow morning. Many thanks.
I feel so dumbed down from so many other ignorant and useless videos here on CZcams on this subject so that when I watched yours, it felt like too much information. My brain started to faze lol! This is a great video - finally someone on youtube with a comprehensive explanation about this. I actually learned something - excellent and thank you!
Simple, clear, concise ! The best as always. Thank you.
Brother thank you. I absolutely hate everything electrical and all the problems! 😠 Especially intermiting one's 😤!! You just explained and showed it perfectly, simple and made it nonintimidating. You are a mechanics Mechanics🔧🔩🚗. Thank you 👍
Congratulations for the amazing and very well explained video. Thank you very much!
I am a professional repair shop and you are making a great video that has great explanations! Great video, this is super helpful for anyone who has questions about their vehicle's electrical system! nice!
brother i have ford fiesta mk6 1.4 tdci my problem is that whenever i start the car battery warning light comes on the dash but if i fully press the throttle all the way to 5k rpm it starts charging and light goes offf , plz help me to solve this issue . this problem started when i removed the battery
I have a very good understanding of how a alternator works but I must say you did a excellent job of explaining it's job and the inner workings of how it works for the average DIYer out there ! Nice !
Hey Billy R, your everywhere!
You Too ! LOL ! No I only hang out on channels where the producer actually has a brain ! And you know as well as I do that someone out there has a better way of doing things and you can always learn something knew !!
This channel is one of the best at explaining things too. See you around Billy!
Yep..totally agree. I'm YCM certified (CZcams Certified Mechanic) because of the great videos on this channel. ;p
wil my alternator work if one diode wire is disconnected?
Wow this is the most informative and best explained video on any topic I have ever seen. Thank you.
Great explanation here, I'll add this to my favs just in case. Thanks Bro!
Great work...well done......nice clear explained.
Thank you very much
Cheers from Denmark 🇩🇰
The best video I've seen on explaining this, thanks!
This is the best explanation I have seen on the internet. I just used your video to explain to my pre teens, as were experimenting with rebuilding an alternator.
The absolute best video on youtube by far. Thank you for taking the time to make this!
Great stuff, no BS video. I am tired of other dudes, kwaking and waking all kind of BS before the actual tiny-miny information they provide. Keep it up man!!
this is outstanding. you videos over the years have really become valuable to the driveway mechanic like me.
Amazing video and with a wonderful explanation! Good job!
The best video, I ve ever seen.
Many thanks
Extremely helpful, thankyou. So much better than anything else I came across on the internet.
Thank you for explaining this in a way I can understand, I am having issues with my electrical system and this video has helped me figure out exactly what is wrong. Many thanks again from Steve in the UK
@Bruce Lee it was the alternator, bought a reconditioned one and it's fine now.
Great explanation to a complicated product. I am subscribing to this channel for lifetime!!!
Thanks for explaining thoroughly about electrical system in automobiles.
I was impressed with the amount of detail and graphics. Even so, I was hopeful that you would have talked about amperage as well. I just purchased a 270 amp alternator, and I would love to measure AMP's to ensure that it meets or comes close to the specification. You have a dog that demands that I give you a like/thumbs-up and subscribe!
So very clearly & well explained - Many thanks !
Hey, nobody ever explain this so good. Good Job Bro.
Awesome explanation on how to test, diagnose, and fix a problem with the alternator. Excellent video and thanks 😊 👍
Thanks brother your videos are always well done and explained in the best details to follow along with keep it up and thanks again for the(correct way ) on your repairs.🦅
This gentlemen give really the best explanation how things should be going on. Thank you and go bless you!
One of the best and most informative videos I have ever watched on YT. Very very good.
Best explanation I've heard so far. Easy to follow tests.
That was a really excellent tutorial: very informative with no waffle. Thank you very much
It's actually refreshing to watch a video that explains the SUBJECT instead of wasting most of the video on worthless chatting. Instead of youtube purging political content they should remove videos that waste a lot of time blabbing and providing incomplete or incorrect info.. We really don't need 50 videos showing the same subject.
Excellent overview with great detail on the operation and testing of an alternator!! Great Job
Great video! Thorough explanation of how an alternator works and how to test. Thank you for sharing your knowledge and expertise! God bless!
Excellent presentation! Much appreciated. You're a great teacher!
You are a good teacher. Thank you for being thorough!

THANK YOU! I was banging my head on this problem for a week, and then found your video!Very helpful!
Great job! Thanks for doing such a thorough explanation.
Another great instructional video! Thanks heaps.
So I've known my mechanical since 1993. But not my electrical. But I'm studying ohms law and now know what amps, volts and watts are. And ohms, parallel, series circuts and how to read them. I'm buying my first multimeter today. Just the cheap $6 Walmart one for starters. So I can measure all this stuff for fun! Loving electrical. I'm building my own 700 watt solar panel system for my van conversion. 3 Lithium Ion 100 amp hr batteries in paralell. With inverter, solar controller, charge controller, BMS, Isolater, etc. Can't wait to test my deep cycle marine and alternator first with my new multimeter!
great info, I am now a subscriber. Thanks!
Thanks to Ratchets And Wrenches for giving good information about alternator. Thanks for teaching in easy way.
Dude! Very good job teaching.
Extremely informative!!! Thank you!!
One more vote for this being the best charging system video out there.
Outstanding and easy to understand video, expertly presented. Thank you!
