I have never regretted subscribing to this channel. The amount of education I get here is like going to Auto university.
And he's just giving it to us for free. What a legend.
Indeed. AMD is a talented technician and a good teacher.
So where can a person GET these individual, simplified diagrams ?
Actually your presentation and method in force every body looks for the best toturial can flow you
@@user-ep3lk8st7d Ya. What he said.
I just wanted to say, you are an excellent instructor. I learned more from your videos in 1 hour than a lot of time with other methods. I hope you make a milli on this work because you deserve it. Thank you!
As a Retired Auto Tech & Community College Instructor (57 years experience with ASE Master & L1) I love your descriptions & testing logic, exactly as I taught my students to do. It might be a good idea to compare diagrams for various manufacturers so people can see the minor differences. Keep up the great work!
Many people do not know how to properly use electrical test equipment, especially for parasitic drain and loading circuits for voltage drop testing. It would be good to do a series based on these points. Again, keep up the great videos you provide. I have watched many of your videos and love what I see.

Why are components given ground in a car? In a house like a light switch it's given power so it's not constantly hot. So car components are constantly hot? Am I mistaken?
@@abes7181 Abe, We use DC except internally in a Generator (usually called an alternator) tis device produced 3 phase AC which then goes through a rectifier to produce a pulsed DC output to the battery.
Automotive circuits are usually Hot or Ground side switched. Ground is used as a return path for todays' Negative Ground systems. A switch may be constantly powered from the battery (ground side switcing), or switched power to a component (hot side switching). Let me know if you have any other questions.
You are amazing in the content! Just like going back to vocational school!
Car Nut I do agree with Greg suggestion. I would highly enjoy those type of content. If it’s possible for you of course. God Bless you guys.
@@abes7181Abe the use of the term "ground" in automotive electronics is a bit misleading. As you are likely aware that rubber tires are good insulators so nothing is actually going to the ground. As a circuit must be complete for current to flow, the metal frame of the car is the ground but most importantly is the metal frame is directly wired to the negative post on the battery completing the circuit. So when you hear "ground" just think negative to the battery.
AS A FORMER experienced tech nition and went to asu of engineering I can say with a degree that pays $500,000 salary, this is by far the best explanation of any course you could ever get in ANY university.
As a former automotive technician now a "Car Care Nut," your RUclips video demonstrates your generosity in sharing your knowledge, experience and well earned wisdom. It is nice to update myself with your videos. Lifelong Toyota & Lexus owner. Wishes for a healthy and prosperous New Year. May the Lord Bless and Keep You!
Every video you make shows how much thought, care and quality you put into your work. You're a godsend to the automotive community!
Oh my God just had the illest epiphany moment as you explained how relay work. Wow! Excellent job!
Your explanation of your methodology is incredibly helpful. When coupled with what's being taught, this is one of the best uses of 30 minutes you could possibly invest in.
Thank you!
I can't believe that I just sat here and watched a video of something I've known for 30+ years. This guy is a great instructor! Keep up the good work!
Great video. My suggestion is you cover a how-to use tools to verify voltage (power), ground, continuity and relays as you diagnose the issue. (with multimeter, quick pin sensors, manual switched relays)
Join this suggestion
I am in awe. thank You so much for explaining such complicated wiring diagrams and making them look so easy.
My favorite mechanics RUclips channel!
I am an Electronics engineer and I am glued to this series as I am learning a lot in comprehension of automotive electricals. I can only imagine how much everybody is benefitting from this masterpiece of a series. Thanks AMD for this amazing series.
I'm just a DIY. So grateful that I found this channel. Thank you for these lessons.
I have all of your videos saved 😉
I can tell you, I (who didn't know anything about cars a year ago) have been giving advices to the Mechanic Master I work with part time, by just passing your knowledge. You are a Saint my very good Professor.
May God bless you and your family, and keep you all safe 🙏
Your English is very clear and beautiful
You are the best. My daughter is an engineering major at Purdue university and is currently taking 300 level electrical current class. I sent her these videos and she said they were helpful. Thanks 😊
Main thing my instructor always said when diagnosing electrical issues, "don't come to me without an EWD".
So I either learned his way or I learned Toyota's (through T-Ten) way of diagnosing electrical issues. It has helped me greatly.
I'm sure it will come later in the series but it would be great to actually see you use your tools to check these voltages at the various points in the starter diagram example. I'm sure you could rig up some test cases with bad wires or fuses or relays that you've collected over time and show the diagnostic thought process. Great so far!!!
Also, I am being greedy here but I think because of the success of your channel you could actually procure a "shop" car (maybe Corolla or Camry?)for these electronic lessons (and other repairs as well) and keep it in your facilities. You could demonstrate the diagnosis and repair process on the car and after some point in time you could sell it! You might be able to sell a high quality completed series of diagnostic assessment and repairs for certain Toyota cars or perhaps something more generic! Thanks again!
Maybe you should go ahead and release a book like scannerdanner did. I love your teaching skills. Besides getting educated, your eloquence is releasing dopamine to my nerve cells. (That’s a compliment)
These videos may not get as many views as some other videos, but they are actually some of the most meaningful videos you can put out. It's good to see you care about the quality of the content you put out and not just try to throw out what will get the most views all the time.
I bet you will be highly wanted as a mechanic when word gets around about your channel. As a woman I am highly suspicious of a lot of mechanics bec of their lying to me. I usually have tried to diagnose the problem prior to bringing it in including reading codes and doing research. Thank you for being honest about your interpretations! We desperately need mechanics like you!
Most competent mechanics are like this or better
You're by far the best teacher for automotive electrical! I have struggled for years understanding wiring diagrams and firing the parts cannon at my cars. I replaced an entire ABS computer and pump when I tested the relay and though it was good. Come to find out, it wasn't; only because I tried every other part. It was one simple plug and play part that I somehow tested incorrectly, resulting in spending lots of time and money installing other parts. Thank you for all these videos and all you give back to us in the car community.
Electrical was always a struggle for me when I was an auto tech. I am really excited to watch these instructional videos of yours. Thank you so much!!
Absolutely The highest training on RUclips he should have been an art school graduate as well his drawings are lovely
AMD, You are keeping us on our toes with a Monday video. 😉
Well presented! When the house is paid for/ kids through college etc.consider a teaching or management position. You have expertise and are well spoken. Our bodies don't last forever as a tech. I got the opportunity to go into supervision in a fleet shop and it turned out to be a real blessing.
Where is part 3? Your videos have really helped me become a better home DIYer. I have been trying to learn electrical for so long. Please make more electrical diagnostic videos please. Thank you
You have a gift for teaching and I feel your enthusiasm. Very helpful.
The wisest video i saw! Great! Im confident i can solve my problem from my Caravan '95. In Argentina nobody want to help me, is an old car with just 110k kms. THANKS!
Looking forward to the part 3 of these series. All the best!
Coffee and Toast while watching CCN Part 2 - the day is off to a great start !
I'm a car mechanic and i never think that actually the relay is a way to turn off and on something which consum lot of current with not strong switch.
Thanks a million!
Continue like that,the videos are great.
Wealth of info. I will be referring back to the alphanumeric symbols. Thnx for placing this series out. May the Lord continues to bless you in what you do so well.
The best car channel ever!!!!
Thank you Sir!❤
You got me in trouble today. I booked my UK spec 2022 RAV4 into a Toyota main dealer. I asked for genuine Toyota 0W-16 engine oil to be used. I was told we only use 0W-20. The service receptionist now thinks I'm either a nutcase or have OCD. Imagine me telling a UK Toyota main dealer to watch your channel. I struggle to see how Toyota UK can accept this issue. I'm only trying to follow the user manual recommendation. This is my first Toyota and from today's experience I might have to reconsider going back to Broke-My-Wallet. Sorry this is off-topic.
Love these teachings. UK dealers could use some of this material 😂
Excellent video! You bridge the gap between basic knowledge of electrical circuits and making sense of wiring diagrams.
Also great is the logic of what to check first, second and so on to avoid chasing your tail.
Seeing a circuit clearly from start to finish is vital in correctly solving the problem without throwing parts, time and energy in all directions.
Thank you for explaining things so clearly.

Many thanks - from New Zealand.
This channel is a model of good teaching. As a professional educator, in academics, I have spent years learning how to teach by observing how good teachers work.
You are an excellent teacher. Thanks also for saying may the Lord bless you and keep you.
This information is gold. As a guy who likes to wrench on his own vehicles I thank you.
God keep this man safe. We need him❤
I regret not having to see and subscribe to this channel when i was scouting for a car. Very simple and concise explanation, worthy content.
I always feel smarter after one of your videos.
I am a master Technician at Toyota. Although i have been off the bench since 2014, i have sent all my apprentices to this channel. Very good explanation and very easy to follow. Wish you all the best sir! May you and your business grow from strength to strength.
I have worked on vehicles for over 60 years. Your explainations are the BEST. Thank you for sharing your knowlege. Wishing you health and prosperity from Canada.
I am very I fortunate to have found a mechanic that I have been using for 20 years that embraces diagnostic culture just like AMD does. I have never had to return a car for the same problem and he is not a parts changer, fixed the first time every time.
I worked on my Cadillac and wiring diagrams were very simple and understandable. Every single possible variation had it's own deticated diagram. Book is also about a million pages long. My friends VW T4 bus, well you have one diagram that has 10 different variations based on trim level and year of production in a single diagram. Good luck figuring out what is what.

👍 Tutorial great thank you very much for sharing what you know with us great video Take care and have a great evening with all your family around you
ACCOMPLISHED THE CAR CARE NUT
From Nick Ayivor from London England UK 🇬🇧
This is truly excellent material. Your explanations are clear and concise.
Good afternoon, i like the way you explain slowly but surely, i can not leave but remain getting knowledge.
Electro-mechanic
Thank You for the lectures.
By FAR the best video explanation of wiring diagnosis I've ever seen and I've seen more than a few in my DIY journey. Thank you so much for doing this video.
i have been reading diagrams for a week and not undersdanding anything till this video comes ..thank you so much sir
THANK YOU!!, "TCCN", FOR GOING THRU SOME OF THESE VERY HELPFUL INSIGHTS, AS TO HOW TO INTERPRET SOME OF THOSE "TINY" DETAILS, ON TYPICAL AUTOMOTIVE ELECTRICAL DRAWINGS! I AM NOT/(WASN'T) WELL UP TO SPEED, ON MANY OF THOSE "SPECIAL" CODES, ABBREVIATIONS, STANDARD NOTATIONS", ETC. YOU HELPED, A LOT, IN BEGINNING TO UNDERSTAND SOME OF THESE COMPLEX NOTATIONS, AND, I THINK THAT I'LL HAVE BETTER SUCCESS, WHEN I NEED TO FIND THE "TROUBLE", AND, POSSIBLE WAYS AROUND IT!
IMHO: THE MOST DIFFICULT, AND AGGRAVATING STEP, WAS TO JUST FIND THE NEEDED SCHEMATICS/WIRING DIAGRAMS!!!! I HAD TO SPECIAL ORDER A BOOK, WITH OVER 300 PAGES OF INFO, ON THE PARTICULAR CAR MODEL,(2008 SCION XD)... IT WASN'T EASY TO LOCATE THAT!!! AND, THIS BOOK, COULD'VE BEEN MADE MUCH EASIER TO INTERPRET!...
I ONLY HOPE THAT THE ENGINEERS WHO DESIGN THESE COMPLEX SYSTEMS, MAY ALL, SOMEDAY, HAVE TO GO THRU THIS PROCESS, THEMSELVES!!!
...MAY GOD BLESS EVERY ONE OF THEM!!! 💥
You not only know a lot of things, you are also a great teacher. Very impressive.
Wow! If I could give more likes, I would. Very informative video for newbies, clearly explains the troublewhooting logic.
Amd you are a really good teacher and you make great videos, I always watch your new videos. Greetings from Sweden!
I’m loving this series so far, but where is part 3?
Please continue this series . My favorite videos are when you troubleshooting a issue or these when your breaking down valuable theory we can use . Your the man
Thank you. You explain it very well for the dummies like me
Another brilliant video
I’ve learned more from your channel than I ever could have imagined. Solid, practical, and well communicated information each and every time! Thank you!
Most technical explaination❤ ever
Keep watching and support from Al Khafji Saudi Arabia 👍
Just learning. I've got electrical problems with a truck I've been working on for over 2 years. Very excited. Thank you.
I fix appliances for a living and this is gospel brother appreciate the video
I have to say, this video reached me in a way other videos, manuals, books, etc. hasn't. Instead of trying to memorize or work troubleshooting charts, understanding exactly what's going on, the purpose & components of the circuit, my logic/thinking was taking over & by the middle to end of the video I was saying it just before you did. That felt good. Thank you. Subscribed
I want say thank you for this simple and clear explanation of electricity wire diagram ,we appreciate your time and dedication thank you so much again.
I was excited for this episode. I wasn't disappointed. 🙂
I really appreciated the two electrical videos you took the time to make. All of your videos are very informative. You have a great channel.
Another fantastic video! Best channel on RUclips! Thank you again
This is an amazing series. I understand that not everyone interested in cars will have the time or the will to watch it. For this reason I assume that it will not have the same engagement as your other videos.
Nevertheless, the value is immense. Please know that they are great and helpful to most of us, even if the numbers don't reflect that.
To sum up: Please continue!
Thank you for your good education.
Greetings from Germany
For those wondering, You drew your Relay backwards, the Toyota one is Ground side Switched, but you drew your Relay Positive switched!
23:50 or a misaligned/out of adjustment PNS Switch.
24:20 *Load Side, Control is other side!
I love this channel. I just found it.
If I'd seen this 30 years ago I would've become a mechanic.
I had no idea how interesting mechanical things are.
Wow. I can't believe how much I learned just from this single video.
What a great explanation and teacher. Never stop teaching.
first vid ive seen of yours 2 mins in and i can tell ill be watching more concise presentation good stuff!
I am a shop owner but not a technician. Your electrical diagnosis videos are very informative and I share with our team. I can’t wait to see more content on electrical diag!
I am so happy I found your channel. You’re awesome!
Bruh, what an amazing explanation of how a relay works! I always asked myself how a coil is used.
This is so helpful for us DIYers, thank you for taking the time to share your knowledge!!
Great, clear and concise presentation, thanks.
I always wondered about the electrical circuit in cars and how they work. your an amazing teacher
Practical electronics... Thank you for this wonderful instructional video.
May the Lord bless and keep you and your loved ones as well! Thank you so much for sharing your expertise and wisdom, I can only imagine how much time and effort you've dedicated to learning it all. You've helped me learn so much :)
-Jasper
You're a great teacher- a natural.
Amazing content! Top teacher quality!
Excellant. ur faultfinding skills is very good, no wonder u r a master diagnostic technician.
May the Lord Bless you and keep you too! Wow - I loved this video so much. My son and I are attempting to install a car starter on a 2007 Toyota Yaris (Manual Transmission) and am starting by doing lots of research and planning. Learning to read Toyota Wiring diagrams is part of this and you explained it sooooo well. A million thank yous!
Great video electronics is important if you can't read diagrams you can't fix the vehicle or troubleshoot it wiring diagrams is like a map usually you start from the top and read all the way to the bottom most diagrams have a 12v source on top of the diagram
Thank you for the video. I did my first electrical diagonosis a few days ago and this video reinforces what i did with that diag and much more. I learnt a lot . once again keep up the good work!
I always get good information on your channel. Although I don’t normally work on Toyota’s your explanations apply to most manufacturers. Please keep bringing us more knowledge!
Hi AMD. This video reminds me the trade school days 6 years ago when I was in Montreal. A lot of good memories with all my teachers. Very educational , much appreciated.
Thanks for the videos I'm excited about these technical videos!! Electrical theory and diagnosis had been my weak point and super happy to see Toyota specific training/theory videos from a Toytota master tech online. I'm a Lexus tech currently working on becoming ASE/Lexus master certified
I'm excited for them too, I'm not a professional mechanic, I just own a '93 Toyota Surf (manual transmission diesel version of a 4Runner for our friends in the US)... his explanation of what a relay does was the best one I've seen in terms of clarity and simplicity. Can't wait for more.
Electrical is one of my strong points you have to understand it to diagnose 90% or more on modern cars like sensors or computers that's the majority of the work
@@DylanL69 I've been considering a career change. Will current auto electricians make the change to electric fairly seamlessly in your opinion? (Is it going to still be a "job" 20 years from now).
@@KiwiPokerPlayer no would have to go through more training to understand the electric cars but yes there would still be a job 20 years from now but I don't think we will be going full electric anytime soon even though governments are pushing hard for electrification the gas engine can still get more efficient so I personally think learning the mechanical engine and vehicle will still be around for awhile
@@DylanL69 Why are components in a car being given ground instead of being given power? Isn't that the opposite of how it is in a house? Like a light switch in a house always has ground(neutral) or return path and is given power(hot) to function or else if you get a short you could get shocked because the switch is always hot. So that means most car components are always hot?
Shrodingers box, ETCG and AMD, followed by Chrisfix, that's all a DIY car guy needs
This is certainly the best channel I have ever subscribed to this year!!!!! Man you are a good teacher!
Great explanation. Please continue this series
This is an awesome video! My friend and I are having trouble locating an electrical issue on a 3rd gen 4Runner. This video is just what we needed. Thanks so much for the education!
