- Опубліковано 20 лис 2020
- In this video I will go over how you can read and make sense of an electrical wiring diagram, I will use diagrams for an evap purge solenoid and electrical diagrams for a crankshaft position sensor, camshaft position sensor, manifold absolute pressure sensor and the throttle position sensor as on example. After this video you should be able to identify wires, connectors, splice joints, fuses, relays and other components when looking at a wiring diagram.

This guy is one of the most underrated car youtubers. For real!
This Guy is A Trump Man..M.A.G.A. He is Making American Great Again
@@midnightrunner684 Underrated? He has almost 1 million subscribers.
@@midnightrunner684 naa he made it clear in a video he doesnt like trump and his fanboys punks
Yea politics aside, he is a smart person on cars but morals, he needs to learn from real data, not fake. But awesome content. Usually by the time someone makes good money 40 50 years, they turn right from left. Usually...the left lets u live a life of anything goes without a one true creator and savior god, jesus and holy spirit. The right side usually has better moral standards, long life span, less depression, more true joy...it goes without saying really, but u have to know the knowledge first. Think for yourself
I began my apprenticeship in 2014 and watched your a/c videos and rich lean vids when I couldn't understand what those codes meant because the dealer didn't have proper training. I became way more efficient over the years from watching your vids over and over and now I know how to read and diag lots of things but still enjoy watching your videos to refresh my memory. The videos you upload may seem like nothing to some people but it definitely changed my life by improving my skills in my trade. Glad to see you upload more vids, keep up the awesome work!
I love your calm, chill, normal delivery. Throughout my years watching youtube, I've seen many normal personalities change where in later years as a channel the person turns into someone who is extremely excitable and overly energetic. Your delivery is perfect. Please never change!
If you don’t know how electrical systems work in cars, you’ll never be able to fix anything but the most simple problems. Continue this series!
I agree and im tired to be the guy praying for the problem to be small all the time. Not even a pro but im ready to get it or die trying
I was taught how to read electrical diagrams while in the Air Force since we had to work on the weapons systems on the B-52 bombers and they wanted us well trained to do the job. I thank you for showing us how we can look at a diagram and figure out where the problem is and I have some tools such as the multi-meter and various meters and I use them when needed.
this guy is the most knowledgeable mechanic, car youtuber. I think anyone who is wants to get in this trade must watch his content. The way he explains is so clear. Ive been a mechanic for over a year now and ive learned so much from his videos. Only person who comes close to his content is eric the car guy. Very underated channel. Hope he gets 1 million subs soon.
I learned to read electrical diagrams from my engineer cousin as a teenager, but I have but forgotten almost everything, as I chose a completely unrelated occupation later. Thanks for a great refresher/tutorial!
So that’s why you can just connect ground to any metal part... thanks for that short clip explaining and showing ground wire back to the negative terminal dude. Now it makes so much more sense.
Now THIS is a mini series I definitely don't wanna miss; I'm gonna have to look up that electrical diagnosis video too
Great info. Great content. Motivating for inexperienced learners. A video on your opinion on how people can go about learning automotive repair properly would be dope.
Good explanation I hope this became a series with a combination real testing and class explanation thank you again you are a good teacher.👍
Thanks for this! I'm looking to diagnose the roof on my Z4 along with a video from Diagnose Dan and this was very helpful. Tough part is currently the interfacing software
Everytime i like the video before watching it becuse i know i will defintely like it after watching. Amazing content thank you
Great topic that confuses and intimidates a lot of DIYers (myself included). Looking forward to more videos about this!
Me too. Have you viewed any other electrical related videos frok him. I only see the mechanical stuff. Also i browsed on his patreon page but could not pick a membership
Hey R&R I’ve watched your channel for years. Fantastic to help demystify automotive issues. & your humour is a great ‘circuit breaker’. Your long reach ratcheting wrench’s have been a game changer. Doesn’t matter how many power tools I’ve got - they’re the 1st tools to go in the bag if I’m out. I loved my Audis. But too expensive to keep on the road. I now have 2 new VWs as family dailys. But have collected (somehow) 3 Saabs & 15 Suzuki Vitaras (Geo tracker). 2 Saabs are convertible & 8 Suzuki’s are soft top. All aged between 1980 - 2002. To be fair - things have got out of control. & yes. My wife is still with me. I’ve just joined your Patreon account. Easy decision. Keep up the great work. Cheers from NZ. 🤙🤙🤙
Hi Patrick thank you for your support both here and on my patreon page :) Long ratcheting wrenches are truly a life saver, especially if you've got your hands full with 20 plus cars :) cheers
@@myRatchets hey I have a Corvette c6 l looking for a Corvette c6 wiring harness can you help
I'm blessed having the chance to know your great channel ...
Greetings from Saudi Arabia 🇸🇦 🇺🇸
Nice explaining. Also later add for the DIYer, these wiring schematics can have errors .
Especially if jobbers have been in their or any work has been done by a garage uninterested in following the schematic and colour scheme
You sir have gained my ultimate respect and appreciation. Wow thanks man!
It's one thing to know about cars. It's quite another thing to explain things about cars. These videos are always very informative.
I like to see you using that US General box because I know its not the box or expensive tools in the box but how the mechanic uses them. Ive worked with guys who think if they buy the most expensive stuff on the market they will be in the club,.....wrong ! Some of these ASE guys were scared of a welding torch. I remember putting a 1200 dollar snap on 1/2 drive impact to shame with my 275 dollar Earthquake. Talk about somebody getting ticked off ! New sub here,great channel !
Thank you very much. I'm in my last year of apprentice. It's really challenging understanding the diagram.
The most helpful mechanic ever!
Something very important that I think was missed is that the diagrams are always drawn with the car "at rest". Meaning the diagram shows what position components like switches and relays are in when the car is turned off. It's important to know because once components become energised (car turned on), then things like relays will turn on and make other things live.
Basics explained at expert level.
He is really giving solid information out to the world. I wish him massive success because I appreciate him doing this knowing it's not entertainment but it's pure gold information. Good luck BTW with your agaucates and take care love the subaru rebuild videos.
Very helpful video! I think you should make one based on how to know and make the difference between all the symbols (like a fuse, relay, solenoid etc) and how they actually work in the electrical system.
Thank you for being very understanding, Appreciate your basic explainations for us new learners.
Thank you so much for taking the time to make these informative videos. I've been scammed various times by people who claim to know what they're doing and I've saved lots of money with your channel and also learned a lot as well. Excellent!
I would like to greatly thank you for making this video you helped my intelligence greatly when it comes to automobile troubleshooting and understanding. I'm going to keep watching your videos maybe I can figure out a lot more thanks again. Your newest subscriber
I must have watched a dozen videos read and reread manuals...
At exactly 2:29 you reminded me of an obvious operator error -- having undone several aftermarket catastrophes on a used 1979 Dodge b200 I forgot to reattach the negative battery terminal to the chassis!!
Thankfully only 1 terminal connector melted at a splice point
Next time I'm searching your videos first ⚡🍻
This guy is seriously underrated
electrical diagnosis. great series. Can't wait!
Unbelievably helpful…thank you!
Hey thank you for this and keep up the good work! I’m going to watch the welder battery video you made next! My guess is it will work for a little while because of how thin car battery electrodes are depending on the type of battery!
So glad I found your channel
Always good content. Thanks!
Your a bad man, thank you sir.
Is there a design advantage in controlling relays via the negative or positive pins? Your videos are priceless. Thank you.
Great presentation. A diagram can be tricky to look at in a manual. If posible I enlarge it on a photocopier, or just the relevant section. Check the manual 'cause some circuits are sensetive to input from meters. (This will come up next)
Hey hey hey its jimmy thanks for all your videos brother..😉
Absolutely fantastic video
Great explanation, I really appreciate your channel
I’m 50 and I wish I woulda got into this trade. Man you are a great teacher!! You explain things very simplistically. A lot of teachers try to boast knowledge and made things more difficult then they need to be. Thanks man 🫵🤙
This guy is doings God's work! Thank you so much man
Thanks! Very informative well put together.
very good stuff man
I really enjoy your videos & how you break things down & explain in novice terms. I have a video idea for you unless you've already done this. If so let me know. I have a 92 Geo Metro 3cyl. 250k mi. Runs rough & smokes. I'd like to take out the engine & get it refreshed by a machine shop. I'm not entirely sure what to ask or expect especially in prices. The vids I do find are more surrounded around high performance. As are the shops here in San Antonio. That's not what I'm after. I just want a basic. Honing of cylinder sleeves. Checking crank & cams & bearings & maybe polishing crank. Maybe a few more things but again not sure and like I said most vids are for aimed towards racers. I'm actually more interested in a optimal mpg build. What would you recommend? Thank you.
Thank you so much. This helps a lot
Nicely explained.
Glad you liked it
R&W Sharpie!? I find that a highlighter is much better cuz you can still read the underlying diagram. And they're available in many delightful colors. Which is actually very useful for highlighting different contiguous conductors. You can use coolish colors like blue or green (I've yet to find a black highlighter, er, lowlighter) for grounds or ground-side switched wires, and warmish colors like red, pink, orange for always-hot, switched high-side, or +5V, and so on.
Somewhat long winded but easy to floow none the less! Have a thumbs up! (ps: I RARELY give them out!) 👍
Great video, well explained, thank you
Thanks for the video.
This really helped...thank you.
VERY GOOD EXPLANATION BRO !!!
Thanks for basic reading wire diagram.
I needed this
Well said, well explained..!
Thx u thx u please don't stop making these videos
Keep up the great work!
So simple explanation.
Thanks for the tutorial. I always get sick when figuring out wiring.
Much love bro 🙏 💯
I though I had already been a subscriber. But for sure today.
Stay safe, Joe Z
Thanks alot great vid
I watched your suspension videos since I'll be doing mine soon. Can you get away with torqueing before you set the car down or is it a must to do final torque after on the ground. Also, if after, if it is to be torqued at 100lbs, would you torque to 90lbs and then the final 100 after on the ground?
Hey, would you do a video on fuel rail pressure problems? Either sensor or wiring would be helpful. Very few good videos of this topic out on UA-cam.
Great video!
Good job sir
Thank you so much for this video! Its super helpful. I was just wondering if anyone has some feedback/ advice for my current situation: I have a 97 chevy van that has a lot of wiring issues including no brake lights, turn signals or hazards. After checking out my wiring I realized that previous owners had totally DIY rewired a bunch of stuff so looking at the wiring diagrams isn't really helpful anymore and I'm super confused on where to go from here. I don't have money to take it to a shop and I'm trying my best to fix it myself but I'm just really confused on how to even approach this project since I can't use a wiring diagram and my wiring is pretty mickey moused. Does anyone have advice on how someone like me with basically no autoelctircal experience could work on a project like this? I know it's a kinda vague question but any feedback is welcome :)) and thanks in advance
Good topic.
Good thing your back!!!
But how many of those shirts you got, and year supply 🤣🤣
thanks friend, this is helpful...Yah bless...doug
Thank you sir for the informative video. How can I find electricity diagram for 2014 Honda brio manual 1.2? I searched online without success.
Good info
Thank You well done 👍🏻
Awesome. Thanks.
Thank you sir
You reference K1 connector. That's great, but is there a marking for that specific connector.
So awesome thanks so much!
Hellou. I have a ford fusion 1.6 tdci 2005. I tested the EGR plug with a multimeter and it doesn't have 12 v on the pin, is a fuse or relay that would cause the problem. Thank you
I’m stuck on an issue, 03 Yukon xl. HVAC issue I traced it back to the white wire in the sp205. The ac control module lights up but no function when it’s plugged in it shuts down the radio, dash gauges and the rear ac. Can u help me please
Fantastic
Thank you
agha damet garm 🙏🏻
2024 and Here I am learning ..thank you
Where can you get wiring diagrams? I have them for my vehicles for for others? BBB Industries used to have them on their website for free but stopped that a couple of years ago.
I’ve been subscribed for a while and I don’t know how diagrams work.
You're a legend sir! Please make regular videos 🙂
Anyone know if there are more videos in this series?

Hi, i have an issue with headlights on my 04 Camry ( Australian built ), they don't work. there are 4 fuses, 2 for each side and none have power. The head lamp relay works and has power IN but the out side shows nothing, ok, but when I connect the + lead of dmm to battery and -lead to the out side of relay socket I get a reading. Is this normal ?
Where do you get your wiring diagrams ??
Thanks
I need to remove a after market theft device from a 1996 Toyota Corolla , stick. How do I reconnect the wires? Do. You have pictures?
Red wire from the harness going to the alternator pig tail? And the white wire going from the wire harness to the pigtail?
If the mechanic swapped these 2 wires and they get connected backwards does it ruin the Battery? Does it make the car not start? Please help
Please work about ecu ande sensore ande actuator testing
You are a life saveour :). and is for example C134 pin 65 connected to EVAP pin2 and C$ pin 6 at the same time?
Thank you for explaining wiring diagram could you pleas explain how you can test any sensor out of a car with a voltmeter to see if the is the sensor is working or not
Thanks Lawrence
You have to recreate the environment that the sensor is sensing in order to see if it's working or not. If it's a temperature sensor, then changing the temperature (boiling/freezing water) and watching for a change in the resistance on the sensor can be helpful. Sometimes you just have to back-probe the wires going to the sensor to see whether it's in the proper operating range. (often changing - sometimes too quickly for the voltmeter to follow accurately). Sometimes you have to just disconnect something and see if the car's behavior changes. If it doesn't that's not always a good thing. Sometimes you have to "activate" that circuit in order to test with pulling a connection. For instance, a high speed fan circuit may require a certain temperature range, or RPM or the activation of the air conditioning compressor.
Bottom line, understand how the sensor works, so you can see how to test it. Intermittent electrical problems are the ones that you pull your hair out on... Learn to also use a OBD2 scanner that shows higher details than just reading codes. Some are phone based. Get a decent volt meter and know how to use it to test across loads, or check amperage readings (need to swap probe positions for this). Learn not to do resistance checks on a live circuit. Learn ohms law. That way you can use a voltmeter to look at voltage drops across a load and determine current readings. Learn to "divide and conquer" It may mean you have a single sensor or problem causing multiple problems. But you may also learn that there are multiple problems there, and the computer has been compensating for it. Also think about what might have caused a sensor to fail (ie, O2 sensor can get clogged when running too rich for too long, or burning odd substances, or NOT burning fuel until too late (in the catalytic converter - makes loud booms).
Missed ya.
