This is just good damn knowledge to learn no matter who we are. I spent two hours today tracking down a bad resistor from a small solar panel controller board. Honestly I was so impressed with how much technology PCB's made the world from even 50 years ago.
This is awesome exactly what I was looking for I'm a beginner and it's so hard to find a video that goes in depth and literally simplify things down to the core such as this is this and this goes to this and it's traced back to this and if this is not working then it's this but thank you I will subscribe and follow and watch more videos you make everything easy to understand thank you
Thanks for the comment I figure people not going to go troubleshoot to component-level anyway because the equipment alone costing me thousands of dollars it's just a general explanation so people will get familiar with computer modules in cars thank you so much
I’ve watched your channel for quite sometime and your explanations are excellent. I enjoy learning something from all of them. Thank you for sharing Artie. 👍
What did he explain?!?! Please tell me what he taught you in this video, what information did you come away from this video with?? ..... You're answer is not a freaking thing!!! He taught NOTHING
Nicely explained, been learning about this field for about a year or so and the way you explain this was very easy to understand. Thank you for your time and dedication, and willingness followed by the patience you have to make this easy to understand, well done. (Subscribe)
as a total beginner you seriously explained absolutely nothing i couldnt already figure out on my own, on top of that you seem to repeat the same thing over and over, my god we may be beginners but we wernt born yesterday!
It might not be cost-effectie in automotive, but brother- believe me, it's more than cost-effective in other things. As a result of this, I managed to find a few loose connections on my $400 dollar AMD GPU! THANK YOU!
Finally,...someone who can not only easily explain BUT I can also UNDERSTAND. No offense to anyone, but I find I extremely hard to understand when the person thing the explaining won't uncurl their tongue from the roof of their mouth.
Great video. Question, I'm replacing my ebike motor pcb board. The replacement has 7 holes/copper rings for wiring. Bu my original has 6 - 5V, GND, SP, H1, H2, and H3. The replacement has an additional ring for wiring labeled "K". What does K stand for in this case? Keyswitch, ohms, resistance? Can't find any information or diagrams online. And if I solder/connect the "regular" wires, will I have a problem if I leave "K" unsoldered? No info online + could use the help. /bklyn 👑
Thank you Sir for your hard job i really appreciate it . and sir please i need full explain FULL Multimeter using parts for CIRCUIT BOARD Testing ....................
Hi, i have an electronic problem and in searching for a solution i came across your channel, i have a board from garage door opener motor and it works motor opens door and closes it when i press button on motor but when i connect my switch to open door via the signal ports for the switch it does not work something is wrong with the board but i dont see anything visual that is broken.
This is deep knowledge. Am a biginner, can you please guide me on electronics repair, I don't seem to understand much of the presentation. Or refer to resources to get me started
The chips u n find with a mouse they need the connection then it works chip lights the mouse and the plug its rely puts the electricty in the chip.. . When every third strip is touched it lights , i put the wires in the hmh like it went frim 3 to so its every after the one that happens the 1st after than 1 after tdogdth .. after . Every one that goes the other ones go to the sauder.. ❤ . (:. We hav light.. yeA..
So, I’m a mechanical engineer. When I was in school we did plenty of circuitboard stuff. The thing that still really confuses me, is the boards inside buttons. I have four wires going into a multi function button. It’s got six functionalities. I’ve got a ground and a signal for the back lighting on the buttons, and then only two wires for all six functions.
It depends what kind of switches there are and also the b+ wire and ground a single wires like in a car motor for the seats to go in by directional modes
@@SleepyMagii mmm not sure they’re that complex. For a computer, yes, but for a button, I believe it’s resistance based, but i don’t see any resistors. It’s a 2 position switch so 🤷♂️ idk lol
Not ohms, the meter is set to diode check. You're actually seeing the voltage drop across an item. It still pretty much works the same to trace signals. If you forward bias a diode, it'll show approx. .5 volts.
The diode function of the meter will measure followed by us and reverse bias so info advised you should have around points 6.7 hold and reverse by should be open or o l but keep in mind if there are other components across that diodewhile you are measuring it you will get in a inaccurate measurement
Try to take the diodeout of the circuit to measure it more accurately and I assume we're talkin about a silicone diode not a germanium or LED that's why when you measure the diodes in the alternator it's not always accurate
But you are totally correct. Without property functioning computers and cars and phones cause we're all out of chips. This stuff is kinda like majic or sorcery.. haha
what im tryi g to figure out are the numbers on the sides of the board with large holes and no accompanying prefix, They appear to be for where wires are attached. But they are in discontinuous order. They jump around in 3's. most of all seemingly no i fo for where the would be wires go to or the type of wire to be used
i am a total beginner but i learnt nothing from this almost 20 minute vid that i couldn't figure out by myself just by observing modules/pcbs; it's was like explaining the notion of clouds and that there will eventually appear rain because of them
Thank you for your comments and explanation of printed circuit boards is a very difficult one especially for a beginner it does require technical knowledge to understand traces the components but I was asked by people who wanted to understand how a printed circuit board works and that's only if you have some technical knowledge if you're a beginner I would refer you to the other videos in the channel Joe electronics schematics for Auto
This is for sure not a beginner video lol. Learn more about components, circuit board types and go from there. You'll learn enough terminologies from those lessons too discover further advanced training. It's not this video creators fault that it was your mistake that you thought this video was a good place too start. If you didn't understand one thing he was saying. This video is too advanced for you.
If you were familiar with all the components on the circuit board, it would be much easier to understand what he is talking about. Knowing the components would help with your understanding on what their function is,
they will not pay a man to sit at a bench and repair these because asians make them for pennies and there has always been a steady supply. it is a lost art. many will actually deem a pcm, module, or circuitboard as being faulty partly because they assume and fire a parts cannon at a problem, another being a lack of a department equipped to send it to and have it tested. i am an electrician and trained in all this stuff but did not specialize in it or do it everyday. in the navy we had a guy specifically for this sortof thing and he was very valuable and so amazing. he could find an open resistor somewhere in a huge maze of a mess of a circuitboard and repair it in a heartbeat. maybe we dont need so many gosh darn electronics in vehicles. maybe older vehicles restomoded (obviously a hei distributor is better than points, and do we really need a pcm? my 69 ford used to get the same gas mileage as trucks today) are the way to go and encourage people to ride bicycles, motorcycles, and scooters more often to save on gas instead of having all this circuitry to regulate emissions and try to squeeze mpg etc, or all these stupid body control modules and can bus systems. fordtechmakulko just did a repair for a taillight for $4500 and uncletonysgarage also made a video about how silly its becoming. is it so hard to turn a dial to choose the temperature of the heater or a/c? they used to just have a cable, then they went to vacuum, now its ran by a Fing computer
I understand your sentiment about repairing instead of replacing and the "parts cannon" my brother is currently dealing with 2019 Ford 150 throwing codes out like confetti.. that being said he's checked, as well as the mechanic of all things mechanical. All the while I'm sure the problem is a circuit board problem. So far no results. 30k truck that won't run.
Let’s help each other out. Q: Why did you watch the video? Q: What is your occupation, or short background ~ to help the rest understand where you would like to use this info. Q: On a scale from 1 to 10, what is your understanding on the topic before watching the video? Q: On a scale from 1 to 10, how much did you understand from the video?
A: I would like to learn more about circuits. Specifically I want to find out whether or not it is possible to use some of the components on a circuit board and combine them with other components of another. A: Accounting ~ I am in the accounting industry and I am unable to explain what the internet is, how it’s build, and how we use it. I am however able to explain to you how to download an investing app, how to link my digital money with the app, and how to instantly supply money to the stock market. Yet as a professional accountant I cannot even begin to explain what and how it is made possible to transact at such a speed. So I am watching this video to develop new skills. A: 3 out of 10 A: 5 out of 10
These are indeed the positive sides. But they're not electrolytic capacitors. They're tantalum. Tantalum is marked on the positive side, electrolytic is marked on the negative side.
You know, nowday it much easier to just swap and isolate the board to troubleshoot because like you said no one want to stay hours just to find the faulty components. Even if you want to do it, it take years and tons of knowledge before you can start for actual repair. It becoming lost art and I can't blame it being forgotten.
Lmao i was almost confused but i know what r chips n capacitors n resistors lol learned positive n negative n pads so most people not payin attention lol
Don't worry too much. If it got destroyed by overvoltage, repairing it will at least be a major challenge. Not everything will be right out destroyed. Could also be a chain reaction and one bad part destroys several others. Even worse if it's a part running some kind of program, as they can't be recovered or bought like that.
@@Joeelectronicschematicsforauto ohh ok i understand. I was fixing Bluetooth speaker for my friend cuz charging port broke off. The red light that indicates it’s charging would turn on whenever I pressed it onto the pads but right when I soldered it on I saw the red light slowly dim out and didn’t come back on. Now If I put the negative lead anywhere on the board and touch the light itself with positive the light will come on. Battery isn’t even plugged in too lol
If you're asking about a motion sensor in the car for breaking into the car it works by anybody getting into the car censor detects any motion but this is one that you can plug in in and out almost a portable type and gives off a hot a high pitch sound if that's what you were asking
how to learn electronics.....1.components 2_ multimeter working 3_ comparing simplest circut diagram with their pcbs design with component..you can find many over internet 4_ knowing ground and positive pins in pcb
Do you know about, how to read the program inside a microchip? I heard the firms can read secret probrams of Pics. What are the keywords of thise topic ?
Heavily depends on what you're looking for and what you're reading it from. Logic Analyzers can do a good job. Some memory can be accessed differently or interfaced in other ways. But it's not really a beginner topic in most cases, there also are security measures against doing just that. But good luck!
Sir could you please do another video explaining the wording/jargon describing the components abilities such as the word: Owens or Ohwns. Lack of the basic language/ jargon limits the understanding. Thank you!
This is just a scrap board to demonstrate if this would be a real board you will need a ground strap a ground Matt you would ground the solder and everything else besides the metal tip because mosfet technology is very sensitive
But I don't want to go too deep into it because the average person watching is not going to go and buy instruments and troubleshoot a put the circuit board that's complex like this
A double sided board means the board also that has the components on the other side you have traces on every board but that doesn't mean you have the components on the other side what that does is you're saving space by making the board much smaller like your cell phone board
Sometimes yes sometimes no I've have capacitors that look fine but when you do a leakage test on them without working voltage they failed yet they looked fine
Yes electrolytic capacitors have polarity obviously other capacitors do not but through hole and surface mounts are a little I was probably off pointing to other components thank you so much
