As a retired BMW Master Technician I told my sons, to be the best technician in the shop, they need to learn electrical properties, principles and systems, and you will be the most sought after technician in the shop, because I found during my tenure in a shop, that most technicians fall short on knowing the fundamentals on how electrical systems work, and how electronics works, so my sons have both become very very good at electrical sytstems, and both of them have become top employees in the business and their companies and have been able to basically name their price for their hourly pay, due to their high demand and knowledge as a technician. 😎👍
Hi how can I go about learning electrics like your sons please, can you recommend a good technique course etc, are college courses offer this type of training or is there a different better way, please help or anyone else that can help me out please thankyou everyone
This brother is a real Top G. Darren helped me with his paid training and I wish I could show people behind the scenes so people can see how good it is when they join because his RUclips is good but it just don't do his behind the scenes stuff any justice. Go get it guys and come back here to comment and like when you feel this comment. Darren is the main man, love you brother.
Nothing better than 'Hands on' in the presence of a fully-fledged and enthusiastic Mentor, Knowledge that has been hard-won needs to be shared and further harnessed with like-minded wannabes 🙂
Great job, I am also a technician but am not fluent in auto electrical. Your explanation and intellectual skills are best. It helps me to understand about what you explain. Thank you very much.
@MechanicMindset i absolutely love your channel and approach to teaching automotive knowledge &techniques very simply and Relatably thank you for taking the time to bridge the gap much love and respect
You have an excellent method of teaching and as a result the information you relay is easy for most people to follow. It is possible for some people to become confused about the words earth and ground in relation to automotive electrics if they do not understand DC fundamentals. In automotive electrics one has a negative connection from the battery to the vehicle body/ chassis and the vehicle engine, and components are bonded to the body/ chassis and in some cases the engine is directly connect to the vehicle battery negative terminal. The words ground, and earth should in my view be changed to vehicle body chassis negative as the negative is a cable to complete the electrical circuit, if people refer to body/chassis negative rather than ground or earth it my well help them understand the vital part that the negative cables and connection points play in the circuit, this is particularly important when carrying out voltage drop testing, an issue that is more important in today’s electronic age. I should point out this is only my opinion as a qualified automotive electrician from the distant past.👍😀
Thanks for watching! I suppose strictly speaking it’s a negative connect. ‘Chassis ground’ is another more common term. ‘Earth’ is probably technically incorrect, but widely used and accepted, as ground and earth are the same in household electrics. The difference there is AC household has a ‘neural’ which we never say in automotive. I probably say ‘ground’ the most. As anything in automotive, there are often 10 different names for the same thing 😆. Understanding fundamentals is important and suppose this should be made clear when learning. Thanks
I always asked customers to tell me as much information as possible before i even started checking the car out.alot of the times it answered the problem or at least sent me in the right direction.
For sure it’s great if you have an employer that understands and invests in diagnostics & training. Otherwise, if you want that path, you’ll have to forge it yourself 👍
I'm amazed at how many "so-called" diagnostic technicians fly in blind. The latest example of which I saw on RUclips. It was a v8 4.2 R8 Audi with a flashing engine light. The first mistake was they didn't go back to basics and understand how the ECU senses certain stuff. But perhaps more importantly, the misfire they were looking for they missed the HT spark plug being one of the most common faults. The coil pack. The misfire in this case was most likely via a knock sensor... they missed all of that, thinking outside "the computer says this". I see it all the time. In this case the technician broke out the ECU security (by abrasive wheel cutting) before looking for the not so obvious (but the obvious to others). The most common faults are not faulty ECU's but sensors, coils etc that get heat damaged over time. Classic ones on Audi are water and oil temp sensors that affect the starting and running controls. Obviously if they read wildly different when cold then one or both are faulty
I've been working on cars for the last 65 years. Going back to cars with points/plugs/coil for ignition and mechanical fuel pump with carburetor engine, all the way to today's cars. Nothing beats the experience. My father was also a mechanic. He would tell me: "Son, being a mechanic is harder than being a doctor. People go to a doctor and explain exactly what their issue is, where it hurts and when...Car just dies or runs poorly and YOU have to figure out why".
I purchased the Picoscope 2204 with all the cables per your recommendation. I received it today and downloaded the software only to find out that I can't use it with the automotive software. Please tell me you have a way around this problem or I just wasted money.
AWESOME, thanks for another nugget of a video Darren 🙂 , I see you have a new employee hard on the job ( Daffy Duck) nothing like a good team effort I guess !! keep up the great work, Bless 😇
Excellent video Darren, thanks for taking the time to share. Also do you still think the Pico 2204A is the best oscilloscope for a first time learner ? Take care. Cheers
Perfect breakdown for the diagnosis. I have a question regarding electrical diagnosis. Took my Volvo to a few mechanics, all with another outcome. Draining of battery until about 10.33V even just quick stopping for gas, therefore always needing to boost. The computer showed up with pages of codes, though they are incorrect, as everything is properly functioning. Could it be the computer module that is malfunctioning with codes and battery drain, OR is the less than a year ago bought battery defective with a dead cell that causes these malfunctions? The dead cell could also explain why it does not drain to zero, rather 10.33V. My diagnosis has now fallen to this conclusion regarding my Volvo s80 2009. Thank you for any input or comment.
@@armo_mafioso Thanks! If there is no excessive current drain, then that would help support your case for the battery fault. Draining to 10.3V that quick, something is going to be working very hard. Even leaving the ignition on for 30 minutes wouldn’t do that 👍
I had a vehicle with the same symptom. With everything turned off, normal resting current. Watched volt meter suddenly drop from 12.5 to 10.5 after just a few minutes after ignition turn off. Each cell in the battery contributes about 2 volts. Replaced the battery and no further problem. Bad cell in an otherwise good battery. Hope this helps.
I wonder if you can inform me if some control parameters can be obtained somewhere regarding the various information that modern OBD2 diagnostic tools give. These tools can show a lot of graphs and numbered values. But how can one know if it is a normal value the tool is showing if not knowing what is normal and what is abnormal values? Thanks...
Hi, great question. A lot of this comes from learning and getting to know and understand the systems. There is lots of info online, but readings can vary depending on the car
What's your (in your opinion) statistics? How many "mechanics" out there started using oscilloscope + gas analyzer in the "diagnostic" process (instead traditional parts swapping)? Is there any progress in the automotive field (or they are still stubborn)?
Haha! Still lots of people swapping parts. Maybe not so stubborn, but not sure how to move forward. Hopefully we can help! Those that want to progress, will 👍 I am connected with LOTS of amazing mechanic’s taking the next level
I am having a issue with my truck something is keeping my lights and i can't get it to start but dashboard lights up a6 ideas,so I don't forget i did run a circuit breaker but not sure if I did it correctly.
Would love to have an explanation of pull up pull down circuits and why are some called low side switched and high side switched and load side switched and switch side switched. It’s confusing I was technician in the 70s to early 80s and need some clarification and explanation. Please 👍🏻
A trigger to make a change in operation can be a low or high voltage as in 0 volts vs 14 volts. The load side is like the opposite of the battery side of the circuit. The switch side is just the far side of the wire not indicating whether it’s the live side of the switch or the load side of the switch
Hey Darren, got a question, I am bad at electrical diag. I was testing the egr valve on 2.0 tdi a4 b8 engine. With ignition on and engine off I was getting 12v on both + and - wires for pwm motor. Was suspecting ground wire was short to b+ but was able to find any damage on the wire (in that area around egr, wasn't testing any further). Is it normal to see both wires 12v on ignition on?
If the motor isn’t being activated, yes that may be normal. We demo that same thing here. When the ground switch is open, we have 6v on both sides of the bulb. Activate. EGR and see what happens; scope might be best to see it if it’s PWM 👍

For sure, both sides of the load will consume as little voltage as possible in a perfect world. Use a thicker wire, less voltage will be consumed, try it! 👍

You are such an inspiration! 🙏 You should be proud of all the amazing work you do. It's easy to just instantly go to your OBD reader and start scanning but having this fundamental knowledge is so important. I have an Autel scanner for around $800 and it helps me so much but I have to admit that it has made me rather lazy and I don't think much about the theory even though I find it very interesting. I studied to become a mechanic about two years ago and I absolutely loved school! But after working as one for only about 8 months I decided that it wasn't for me, at least not yet. For me it was way more fun to learn and experiment and help fixing my friends cars, the moment I get a strict time-limit to solve a problem is the moment the fun stops. It also didn't help that most of the work I got were rather mundane services. (Which is to be expected, I know) Mechanic as a job didn't work out for me but I'm still very passionate about it as a hobby and enjoy helping my friends, your videos keep my mind sharp and one day I might further my education to become a Technician as I feel like that would bring me more joy as a job. Whatever may happen, respect ✊
Hello sir . Great video as always Mr Daren . Question for you. I’m not a mechanic but I have a lot of knowledge on a vehicle from 80 to 08 year. However the newer require osiloscope. Wich is the less expensive that you will recommend. I’m not working on the car industry so it har for me to take 4,5 k out my painter check you know. I like to learn without expensive costs cuz obviously it will not pay by it self on my personal end . I’m a painter though
Great! Oscilloscope is very helpful for modern diagnostics. Check out this video for a great scope on a budget: ruclips.net/video/A0wwhPJNDKk/видео.htmlsi=Pu0iwbraTZRg38vv
Wouldn't it be helpful for information sources like alldata or Mitchell to put examples of what live data should look like for different parameters? Why dont they do that
It definitely would. Some do. But it will only give a range of operation (which isn’t always so helpful). It’s also important to know what happens to the value dynamically (ie when you rev it). Once you start looking, it will definitely start to make it easier 👍
Hi Darren. At 4"25' the DVM read 6v at the bulb when the reference point was the positive terminal and the switch was off. Was that a - 6v meaning a 0 reading?? Im confused.
This is because across an ‘open’ switch, one side will be 6v and the other side will be 0v - volt meter shows the difference between the measuring points 👍 With the switch ‘closed’ we will have 6v on both sides, now the difference will be 0v

I used RUclips alot for learning alot about automobiles repair and services maintenance first time i am commenting and sharing my thoughts about the experience as a learner...i am really happy to call you My( Automobiles Professor )......professors Darren ..
The title should be "5 Tips that everyone already knows to start an electrical diagnosis." There are a zillion other things that could be wrong with a car that require zero electrical type diagnosis.
The first tip to learn diagnostics and repairing cars is "Are you intressted" i always ask friends if they like doing mechanical work etc they always say yes but then i always find problems with them complaining. Give it a hard thought.

But I want to know what's the significance of this delaying in 7V from 12V??
It seems CAPACITOR plays a role here.

If you wanted to prove your metal, i hear that theres a Mercedes giving Alex over at Legit Street Cars some gyip!
Seems that it keeps going to limp home mode at full throttle.
Would be cool to see you guys over there working that one out for him

In a perfect world, the load will use all available voltage and the ground side will be zero.
For sure, both sides of the load will consume as little voltage as possible in a perfect world. Use a thicker wire, less voltage will be consumed, try it! 👍

For sure!
can you please explain....
Why why why???
Today's modern cars eg Toyota Glanza, Toyota Taisor, has 12V and then drops to 7V in the door close signal voltage.
Whereas, it used to be directly 12V when door closed and 0V when opened in old cars.
But today's cars has 12V at door closed, and after 20 seconds, it drops to constant 7V. When opening, it drops to 0V.
Why there's delay in dropping to 7V at door closed??
What's the significance of this 12V to 7V???
Please explain 😊
Just answered you in the other comment 👍
@@MechanicMindset please research about this especially on Toyota Glanza and Taisor.
What is the significance in delaying to 7 from 12V?? 🤔🤔🤔
If you look up how to do a parasitic draw test, it will explain why that happens.
You are such an inspiration! 🙏
You should be proud of all the amazing work you do. It's easy to just instantly go to your OBD reader and start scanning but having this fundamental knowledge is so important.
I have an Autel scanner for around $800 and it helps me so much but I have to admit that it has made me rather lazy and I don't think much about the theory even though I find it very interesting.
I studied to become a mechanic about two years ago and I absolutely loved school! But after working as one for only about 8 months I decided that it wasn't for me, at least not yet. For me it was way more fun to learn and experiment and help fixing my friends cars, the moment I get a strict time-limit to solve a problem is the moment the fun stops. It also didn't help that most of the work I got were rather mundane services. (Which is to be expected, I know)
Mechanic as a job didn't work out for me but I'm still very passionate about it as a hobby and enjoy helping my friends, your videos keep my mind sharp and one day I might further my education to become a Technician as I feel like that would bring me more joy as a job. Whatever may happen, respect ✊
Great you get to do what you love, glad the videos help! Thanks
Hello sir .
Great video as always Mr Daren .
Question for you.
I’m not a mechanic but I have a lot of knowledge on a vehicle from 80 to 08 year.
However the newer require osiloscope.
Wich is the less expensive that you will recommend.
I’m not working on the car industry so it har for me to take 4,5 k out my painter check you know.
I like to learn without expensive costs cuz obviously it will not pay by it self on my personal end .
I’m a painter though
Great! Oscilloscope is very helpful for modern diagnostics. Check out this video for a great scope on a budget:

I appreciate your quick response Daren .
That is very kind of you
wow I love this info. please share more.
well explaind
Wouldn't it be helpful for information sources like alldata or Mitchell to put examples of what live data should look like for different parameters? Why dont they do that
It definitely would. Some do. But it will only give a range of operation (which isn’t always so helpful). It’s also important to know what happens to the value dynamically (ie when you rev it). Once you start looking, it will definitely start to make it easier 👍
Confirm customer complaint should always be step #1
Hi Darren. At 4"25' the DVM read 6v at the bulb when the reference point was the positive terminal and the switch was off. Was that a - 6v meaning a 0 reading?? Im confused.
This is because across an ‘open’ switch, one side will be 6v and the other side will be 0v - volt meter shows the difference between the measuring points 👍
With the switch ‘closed’ we will have 6v on both sides, now the difference will be 0v
@@MechanicMindsetThanks very much. Still waiting for the light bulb moment so this all helps. 👍

Hey mate you’re star at tec , where are you guys located, I mean if I can work experience with you?
Well done here..
The first tip to learn diagnostics and repairing cars is "Are you intressted" i always ask friends if they like doing mechanical work etc they always say yes but then i always find problems with them complaining. Give it a hard thought.
@@TheToRealRicky It certainly helps if you are interested!
Wonderful
thank you .
