Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍
Craig - Don herein Canada - Just saw your small engine coil lecture. I know you are probably getting all sorts of praise for your approach to effective instruction. I love how you decided what to include and what not to include in your instruction. I only wish my grandchildren were schooled with this sort of approach to instruction.
Listen, let me explain something to you all. I’ve read literature. Lots and lots of literature. Lots of literature that explains how electricity works, including down to the atomic level. And over time I’ve gained an amateur’s understanding of it. And even then, when don’t work with electricity enough, I have to read that literature again in order to refresh my understanding. However. I have NEVER had electricity explained to me as concisely, intuitively, and detailed as this video does. And I’m going to tell you right now-I don’t think I’ll ever forget it, such that I might have to revisit this video as I have all the literature I’ve read. This explanation sort of drilled the concept in my head. Excellent, excellent work by an excellent teacher. Now if I could grasp how voltage is like pressure/force, and how current is like volume, and how resistance is like a restriction, I’ll be the better for it. Wow. Just wow. What an amazing video. Bravo! Now just freaking imagine, that he taught all of this, in this way, using a coil that’s found in a lawn mower, or chain saw, or pressure washer. Like that’s legitimately wild to think about.
Wow. That is probable the best ever feedback have ever had since starting this channel back in 2012. Thank you so much. You have motivated me beyond belief. Thank you so much again. I’m on the case with the things you mentioned that would be beneficial for o make another vid about. Thanks so much. Craig 👍👍👍👍👍👍
55 years ago my physics teacher spent a week trying to explain this to us and we got half an idea but you have, in 16 minutes explained it crystal clear. Fair play to you. I hope physics students today get to know about your videos. Thank you.
Coil ? Magneto ? Transformer ? It's a Tesla coil , in reality it simply steps up voltage , a auto has a 12 volt system , the coil steps it up to 35,000 to 80, 000 volts , The coil on a lawnmower engine is the same coil except magnetic fields are traveling through the steel into the primary and secondary copper coils increasing voltage and makes the spark plug zap a spark , you can make a lawnmower coil make a zap with a 12 volt battery , I have many coils in my collection , I can make a 4 inch arc across 2 steel nails , that's a few thousand volts , It's a spark as long as a spark plug
@@shoechew , I would take that act on the but it's Killer , As the volts are so high that it can and will Kill you , instead I burn Wood and do wild things at home in a controlled space and no one can get hurt , Except for the burnt wood , But I wire brush , sand and polyurethane the wood and sell it as Art pieces , It looks like lightning hit
I was an electrician for 50 years with a degree in Industrial Electronics and wish my teachers back then were this capable of explaining electron flow. I am now a subscriber, well done.
This is seriously THE best explanation of electromagnets and how they're used in ignition systems. Like most everyone else seems to be saying, you accomplished in 15 minutes what most courses or classes attempt to do in days or weeks. Fantastic job man, thank you.
I've been an EE for more than 50 years, am still working full-time, at 76 years old, on avionics at one of the largest multifaceted companies. I've seen a lot of technical presentations during those years but have rarely seen one that teaches as well as this one. I will seek more of this man's work.
I'm a retired electrical engineer and am humbled by your ability to teach these very difficult concepts. Your sense of what to say and show as visual aids is astonishing. This was a lot of hard work and preparation, and your lifetime of learning, perhaps frustrations with lousy explanations of how the world works, came clearly into focus. TH-cam, for me, is all about learning from others, and if Google ever had the equivalent of an "Oscar" for best "teacher," you would get my vote!
Yeap. But 60 years ago there were points not transistors to break the primary coil to cause the collapse. The transistors switch off much faster than the points so you get a better spark.
I've been an Electronics Engineer for 42 years and this has to be the greatest explanation of Atomic Theory that I have ever seen. My 8 year old grand-daughter is taking a VERY keen interest in Electronics and Robotics. I've been teaching her things for a couple years now. As you can imagine, explaining Atomic Theory to an 8 year old is the one thing I dread doing. I'm going to show her your video because you have done a FAR better job of explaining it than I ever could. Thanks Mate!
You took the knowledge of something that is so basic and well taken for granted and made it so clear down to the atom! This right here is the best TH-cam teacher ever! Bravo!
This is hands down the absolute best video presentation of how the coil works especially deep diving into the atomic theory/explanation! Thank you so much for taking your time to produce this presentation. It’s excellent!!
I've been an electrician for the last 45 years, in all this time your explanation of the principle of electron flow is the best I've ever seen, well done, for making this understandable. If I were still working and teaching Apprentices, I would recommend visiting this clip to them.
I'm 68 yr's old, and just now learned how that darn coil on my different machine's works. Better now than never. I worked as an autobody (Panel-Beater, for those across the pond ) guy for just over 25 yr's. You are a GREAT TEACHER. Can't recommend this video enough.
74 year old aircraft mechanic and small engine repair here. I might have been taught this in A&P school for engine magnetos but can't remember doing so. This was a very clearly explained and educational video to me. Thx.
I chuckled when this video was recommended because I thought I knew all this, but I didn't know about the trigger coil and it's circuitry. Maybe this void in my understanding led me to watch this video. Also I am impressed with your presentation. Well done.
The older ignition coils do not have the trigger coil. They use points to break the circuit and collapse the magnetic field. The two are generally not interchangable.
@@lawrencethompson127 They are interchangeable on all Briggs engines built from 1965 and on. I also watched a video where a fellow got a 1953 to work on the modern coil. So they can be. Certain engines like Tecumseh can't because the old magneto was behind the flywheel the modern one on the outside, however a Nova II can give one of those electronic ignition as well.
An excellent and clearly illustrated explanation. If things are mechanical: go up and down, back and forth or round and round, I can look at them, figure out what's not working and fix them. But electric things just sit there and grin at me. This showed me how the electricity moves and what happening in a mechanical sense. Truly enlightening. Thank you.
I've been a mechanic of electrical engineering and HVAC field for many years now going on almost 24 years to be exact and I have learned so much over the years and I have learned it in so many different ways but I must honestly say from the bottom of my heart I truly mean it when I say this your video and your explanation of how the magneto coil works is by far the best I have ever seen I've never watched anything so clear as this you waste no time in explaining unnecessary details you go right to the point but you pick up the important details that are often left off and you discard details that aren't critical to know so it makes it less confusing and much easier to learn and understand the perfection in your animated video also helps tremendously I just wanted to say that I really enjoyed you sharing this video I learned a lot from it and I will pass it on to others and recommend it for many years to come THANKS again for sharing your video...!! 😉 Yours Truly , Justin the HVAC Tech.
Wow. Absolutely wow. I have never had such amazing feedback and from a professional as well. Thank you so much for your detailed response comment. You’ve mad my day. Craig 👍👍👍👍👍👍👍👍👍👍
For years I wondered what changed in small engines that the points and condenser are no longer needed. Now I know it's the trigger coil and its associated components. Thanks!
Thank you for confirming exactly what I was thinking. It was a mystery to me until this video. And the guy at the farm supply I go to had it all wrong. He was trying to sell me a replacement coil that only worked with points and condenser that had been on his shelf for years in a crumpled box and was telling me that was the upgraded coil when I asked why they looked different. LOL.
I have 50 years of electronics theory and actual day to day practice. Yet, there were sections in your presentation that brought to life areas that only were vaguely understood by me, specifically the electron flow from the outer valence ring. Excellent voiceover work and graphics. No second thoughts about subscribing to your channel, and I’ll be sharing this with the many folks who come to me with questions. Your explanations far outpace my abilities to do so. Excellent work!
at 73 years it proves one can never stop learning I am currently servicing my hayter Harrier had for 20 yrs changing coilpack etc, found this vid, totally inspiring & educational Brilliant thank you
I've tried over and over to get guys to realize that its the OPENING of the points that times the spark and I always get an argument. Set points wider to advance,Across the board. Good video,for sure!
So the opening of the points times the collapse of the magnetic field in the primary coil by disrupting the current! Unintuitive but it makes sense given the electrical theory behind it. I didn't get points ignition at all. Great comment!
Dude, i am a car guy. My existance has evolved around the automotive industry since i was born. The ignition of an unternal combustion engine has been that element of magic that occurs that has always been just beyond my understanding until now. The simple and direct explanation you just provided has given me the knowlodge of how the discharge across the air gap works. I have always knowledge the whinding and magnets that mive the toroidial field expands and contracts by proximity but now i see how the electrons are shoved forward for the eventual jump and discharge of compressed explosive gas. This is a game changer for me. And you gave a stranger a clear image of fast as light movement of electrons. Thank you very much!
I wish I had this video 50 years ago when I was working on my mini-bike, then some years later when I was starting my career in the electrical trade. Great presentation!
6:12 A fantastic explanation, I am an electrician who has had a very detailed and exhaustive week of my instructor trying to put that in my head, it didn't stick. Now however I have a true understanding! Thank you, it's nice that you've made my life make sense!
This whole series of videos are not basic. They are, bar none: the most educational and well produced tutorials on TH-cam. Thank you thank you for all the time and effort you have given freely to us. *************
In my 48 years of life and search for knowledge I do not believe I have EVER heard/watched any instruction of complex technical material so beautifully articulated in such a clear, concise, succinct, and relevant manner! Thank you! I am excited to view more of your content! Please keep ‘em coming!!
I teach Motor Mechanics to 16-19 year olds and use video and animation to help explain processes such as these. We are currently on ignition systems. I must say your video is absolutely superb ! I especially loved the electron movement part which was so well explained, anyone who watches this video will easily understand exactly how electric current is made, you know, the outer electrons flying about.
Great explanation! All I knew before was it was a magnet moving past a coil, and that ignition occurs as the field collapses. The rest was a revelation, Thanks!
Which leads me to the obvious question, why add the schmitt trigger and second and third coils (trigger and primary coils) when you could generate a spark from the magnet passing a large secondary coil (which then would just be called the coil) and the result would be more reliable due to having less parts to go bad? Is it worth a more finely tuned spark to reduce overall reliability? (Assuming the answer to the first question)
I think you could add two things: 1) the opposite end of the secondary coil being tied to the the frame of the laminated fixture to complete the HT circuit, and 2) an explanation of the previous version of this magneto ignition, which used a set of breaker contacts driven off the camshaft or an eccentric on the crank. Unlike the Kettering auto ignition, which collapses the Primary field when the contacts open, the magneto version initiates the spark when the contacts close. All in all, a good video!
@@arthouston7361 most of the people that he is aiming this towards don't have any idea that it's incomplete. I'm assuming he said basic he had a time frame for this video. The fact that it's incomplete is beside the point. I am assuming that he said basic just to get people to watch and learn and get interested.All same time making a 15-minute video as opposed to a 30 or 45 minute video where people could lose interest.
@@chrisstreet7384 Interesting. I have to guess that you had nothing better to do today than to make a critique about expanding the knowledge of people who watched the video, assuming both the target audience and the intent of the content creator. A fascinating study on human motivations.
From Iron to Ions, brilliantly linking physics and mechanics. Great clarity and graphics. At last we can see the invisible world energising the visible world .My friend ( Phd, on Ions) gets nowhere near this , after 40 yrs of chat.I saw through a glass darkly, but now .......I see the light
That was fantastic! Always knew how coils and magnetos worked,but never at a molecular level, I enjoyed that immensely and it just goes to show your never too old to learn something fascinating. Thank you for your time.
Amazing, the ability to explain an extremely complex process in terms that can be processed and understood by I would think most people. At school so many interesting things were taught, but the disconnect was the ability to provided context and real world applications of where and why it can be used. Well done Craig, you are a very talented person.
I watched a Mustie1 video, where the engine would rip the rope out of your hand while starting. The owner had replaced the coil, but installed it backwards. The timing was now off, firing the plug at the wrong time, causing the engine to turn backward. Now I understand what was actually happening.
What was of interest to me in this very comprehensive explanation was the use of the transistors . I recall many decades ago small engines had a set of " points" similar to (much) older car ignition systems. All that mechanical switching changed in the early 1970s with the introduction of solid state electronics, AKA transistors. The circuit diagram drawn in the video is a clear explanation of just that transistorized switching circuit... where the " points" used to function Great lesson
This is the best explanation I have come across. Most people call the ground negative and the wiring positive, when in fact is the other way around. This explanation makes perfect sense.
The best example of how this electrical system works. Where were you 30 years ago when the atom's in my brain were splitting trying to figure this out. Bravo!
Great explanation. Your step by step approach leaves nothing out and is presented in a logical way that makes so much sense. You make no assumptions of your audience's knowledge which is helpful for novice or expert alike. I am keen to watch more of your videos.
Hi. This is probably the best electronic video I’ve ever seen. I came here because the igniter on my gas engine weed whacker stopped producing spark. With the help of other videos I correctly came to the conclusion that the igniter had failed. Still under guarantee I wrote to the seller explaining the problem. They wanted me to return the entire tool’ but I explained I could send them the igniter but their next email stated that they could only give me a refund because the tool is out of stock. In the meantime I purchased another igniter from china, installed it and it creates spark. But trying to start it the engine bucked a little so I decided to check the installation AND THAT’S WHEN I SAW THAT THE POSITION OF THE MINI COIL IS ABOUT A CENTIMETER EARLY. Which to me means that the timing is off. But I wasn’t sure until I watched your video. It’s truly a work of art! Thanx so much for creating it.
I have fitted these coils to older B&S and although I knew the basic idea it was great to have an in depth explanation rather than having the meaty bits glossed over, well done.
A heartfelt 'thank you' for such a crystal-clear explanation. You are an exceptional teacher and your illustrations in this video helped me to understand old concepts in a completely new way. Well-done, sir, and once again 'thank you' for the role you are playing to educate those with a thirst for knowledge!
Best explanation of generating a spark in an internal engine. I never understood all the physics that was happening until now and I am 73 years old and worked on a great many motors. Thank You.
Awesme video guy. I'm an old retired E.E. who works on small engines and needed a refresher course. Thanks so much. It's the best technical video I've ever seen, and I've seen a bunch. Congratulations.
WOW! Now that is an explanation beyond 'Fascinating'. I can't wait for the video that shows how the system of points and condenser works. It's something I never understood.
Craig, That was the clear, logical, step-by-step explanation I have always wanted to see. Bravo! The animations and actual cut-in-half transformer coil, showing the real life locations (initiator, primary, secondary coils) brought these electronics and physics concepts into full sunlight. Thank you.
As an Electro-Mechanical Engineer teachers in schools should use the explanation video to there first year students in basic electrical understanding ,it's the most simplistic explanation and so informative of how spark is explained with the video seeing is believing....Great Job keep them coming.....and thanks Glenn
As a graduate engineer I find this discription excelent. I am trouble shooting a faulty small engine, no spark. I realize the coil is bad but have never looked at the design of a small engine ingnition system. Your description was GREAT. I understood the basics but was not sure of the final engineering involved and you cleared it up perfectly.
You Sir are a genius! I thought I understood the basics of a magneto. It seems I didn’t know nearly enough. TH-cam should give you a raise. Cheers Craig
Something that had intrigued me for yonks was how contactor-less ignitions worked, but all clicked into place after watching the vid. Love this style of teaching/learning i.e., why and how. For my practical’s classes, I attend a Canadian guy who likes a beer, also, a couple of others others too. Great work by all, many thanks.
You’re presentation technique is spot on which makes the subject easy to understand, the level of detail you have included here is just right, thank you. EE Eng.
You Sir are about the BEST teacher I have ever seen . I have been an automotive technician for over 40 years and this is the best explanation of how a coil works right down to the atom! I also wish my teachers had your ability to explain electron flow back when I was apprentice. Thank you!!!
Good job. I also did not know about trigger coil and Darlington pair. As an EE, I suspected that the current induced in the primary would be alternating. I think I now see that the transistors impede the reverse flow. That requires a high reverse breakdown voltage spec on the Darlington, but really shortens the mag. field collapse. As we know, E = -L (dI/dt), so that short dt gives the high V.
Mate, if they taught chemistry and physics in schools like you have done within the first 8 minutes, we would have a nation of geniouses. Fantastic presentation. Good on you. Thanks.
woah, I was not expecting a full blown science video. My knowledge of electricity over the course of 15 minutes just jumped more than it did in 4 years of school.
I clicked this expecting a video explaining how to service the coil pack on a lawnmower. Instead, I got a sub-atomic physics lesson. My lawnmower may still be broken, but now I understand how a transformer works, which is something I've actually wondered about for awhile. Good stuff.
I’m teaching my teenager the basics of a lawnmower and we found the coil pack. I didn’t know how it worked , but your explanation was uniquely clear and properly detailed !
Absolutely excellent explanation of ignition module workings! I thought I understood until you clearly explained it! Thank you so much. Keep these kinds of educational videos coming!
Great video and great explanation of how the coil works. Straight to the point, no lengthy introduction talking about the cat, dog, length of the grass or some other unrelated stuff. Thanks
Great video. I do small engine repair. When somebody asks "what could possibly go wrong with a coil?", I can explain how complicated the operation really is.
The operation is complex, but the coils are simple. If each coil has the proper resistance end to end and is not shorted to anything else, such as primary coil to secondary coil or ground or to the core, then it works just fine. Same with transformers.
I’ve been an electrical technician all my life, and taught for the last 3 years. Most people who explain electrical topics to the average non-electrical tech skip over the basics leaving the poor student puzzled about what electricity and induction actually is. This was a great explanation of the ignition system and an introduction on how electricity is made, transmitted, and works in everything we use.
Thanks, Fixed my no starting problem on my John Deere garden tractor. Inside the rubber boot that slides over the spark plug the metal plug wire right angle connector had broken. Only thru the Grace of God did I discover the problem. The spark plug wire pulled free from the boot.

You are a brilliant teacher. Knowing it and being able to effectively teach it, is a gift.
Outstanding! Clearly explained many of the "WHY" questions that others have never been able to explain in enough detail for it to make sense.
This is a detailed and accurate description of the process. Your graphics are spot on and easy to follow.
If only this man was my personal teacher...
Wonderful explanation as always
I've tried over and over to get guys to realize that its the OPENING of the points that times the spark and I always get an argument. Set points wider to advance,Across the board. Good video,for sure!
Then least you always had the points to OPEN discussions on the topic, eh? 😁😉
So the opening of the points times the collapse of the magnetic field in the primary coil by disrupting the current! Unintuitive but it makes sense given the electrical theory behind it. I didn't get points ignition at all. Great comment!
Dude, i am a car guy. My existance has evolved around the automotive industry since i was born. The ignition of an unternal combustion engine has been that element of magic that occurs that has always been just beyond my understanding until now. The simple and direct explanation you just provided has given me the knowlodge of how the discharge across the air gap works. I have always knowledge the whinding and magnets that mive the toroidial field expands and contracts by proximity but now i see how the electrons are shoved forward for the eventual jump and discharge of compressed explosive gas. This is a game changer for me. And you gave a stranger a clear image of fast as light movement of electrons. Thank you very much!
I wish I had this video 50 years ago when I was working on my mini-bike, then some years later when I was starting my career in the electrical trade. Great presentation!
That was the best explanation of how a pointless system works I have ever seen. Thank you!
This is the best and clearest explanation I have ever seen, thank you.
6:12 A fantastic explanation, I am an electrician who has had a very detailed and exhaustive week of my instructor trying to put that in my head, it didn't stick. Now however I have a true understanding! Thank you, it's nice that you've made my life make sense!
Excellent. Thank you. You are very welcome. Craig 👍
This whole series of videos are not basic. They are, bar none: the most educational and well produced tutorials on TH-cam. Thank you thank you for all the time and effort you have given freely to us. *************
In my 48 years of life and search for knowledge I do not believe I have EVER heard/watched any instruction of complex technical material so beautifully articulated in such a clear, concise, succinct, and relevant manner! Thank you! I am excited to view more of your content! Please keep ‘em coming!!
Wow, thank you! I really appreciate it. Craig 👍👍👍
You tricked me into an electromagnetism lesson!
Good job, I enjoyed your explanation.
I teach Motor Mechanics to 16-19 year olds and use video and animation to help explain processes such as these. We are currently on ignition systems. I must say your video is absolutely superb ! I especially loved the electron movement part which was so well explained, anyone who watches this video will easily understand exactly how electric current is made, you know, the outer electrons flying about.
Great explanation of the system thank you for sharing!!! Somehow, I heard anti-gravity in your explanation somewhere. 🛸🛸
Thank you so much. 👍👍👍
EXCELENT....PERFECT...never seen such simple and detailed at the same time explanation of spark creation before in my entire career. Well done.
Being an 86 yr old electrician I now have a better grasp of the atomic level of this --- thanks
Great explanation! All I knew before was it was a magnet moving past a coil, and that ignition occurs as the field collapses. The rest was a revelation, Thanks!
Which leads me to the obvious question, why add the schmitt trigger and second and third coils (trigger and primary coils) when you could generate a spark from the magnet passing a large secondary coil (which then would just be called the coil) and the result would be more reliable due to having less parts to go bad? Is it worth a more finely tuned spark to reduce overall reliability? (Assuming the answer to the first question)
@@jonka1 ok, thx!!!
I think you could add two things: 1) the opposite end of the secondary coil being tied to the the frame of the laminated fixture to complete the HT circuit, and 2) an explanation of the previous version of this magneto ignition, which used a set of breaker contacts driven off the camshaft or an eccentric on the crank. Unlike the Kettering auto ignition, which collapses the Primary field when the contacts open, the magneto version initiates the spark when the contacts close. All in all, a good video!
Spectacular!
That's why he said "basic explanation" pay attention.😉
@@chrisstreet7384 Attention is why he got those recommendations. There is a big difference between "basic" and "incomplete." 😇
@@arthouston7361 most of the people that he is aiming this towards don't have any idea that it's incomplete. I'm assuming he said basic he had a time frame for this video. The fact that it's incomplete is beside the point. I am assuming that he said basic just to get people to watch and learn and get interested.All same time making a 15-minute video as opposed to a 30 or 45 minute video where people could lose interest.
@@chrisstreet7384 Interesting. I have to guess that you had nothing better to do today than to make a critique about expanding the knowledge of people who watched the video, assuming both the target audience and the intent of the content creator. A fascinating study on human motivations.
You’ve given the best explanation of how a magneto works that I have ever seen explain in 60 years
From Iron to Ions, brilliantly linking physics and mechanics. Great clarity and graphics. At last we can see the invisible world energising the visible world .My friend ( Phd, on Ions) gets nowhere near this , after 40 yrs of chat.I saw through a glass darkly, but now .......I see the light
That was fantastic! Always knew how coils and magnetos worked,but never at a molecular level, I enjoyed that immensely and it just goes to show your never too old to learn something fascinating. Thank you for your time.
Thank you for this clear and concise presentation. I now feel enlightened and much less mystified about electromagnetism. A life changing gift.
Came for the lawnmower lesson, stayed for the physics lecture. Nice job, Craig!
I came here because I always wondered how one of these mag coils worked without a contact breaker.
What a superb explanation from a repair man!
Singularly the most clearly explained tutorial on how a coil works. You sir, have no idea how valuable your work is.
Wow, thanks. That is one of the best comments I've ever received and I'm truly grateful to you. Craig
Amazing, the ability to explain an extremely complex process in terms that can be processed and understood by I would think most people. At school so many interesting things were taught, but the disconnect was the ability to provided context and real world applications of where and why it can be used. Well done Craig, you are a very talented person.
I did not know about the smaller pickup coil. From this it is important the orientation of the smaller pickup coil to the rotation of the magnet.
I watched a Mustie1 video, where the engine would rip the rope out of your hand while starting. The owner had replaced the coil, but installed it backwards. The timing was now off, firing the plug at the wrong time, causing the engine to turn backward. Now I understand what was actually happening.
Yes and the spark will be much weaker since the order at which the flywheel magnet energizes the coil and the trigger.
What was of interest to me in this very comprehensive explanation was the use of the transistors . I recall many decades ago small engines had a set of " points" similar to (much) older car ignition systems. All that mechanical switching changed in the early 1970s with the introduction of solid state electronics, AKA transistors. The circuit diagram drawn in the video is a clear explanation of just that transistorized switching circuit... where the " points" used to function
Great lesson
So that's why we don't see points anymore! The function is necessary, the device isn't.
This is the best explanation I have come across. Most people call the ground negative and the wiring positive, when in fact is the other way around. This explanation makes perfect sense.
The best example of how this electrical system works. Where were you 30 years ago when the atom's in my brain were splitting trying to figure this out. Bravo!
Ditto T C… The absolute clearest explanation I’ve ever seen. Well done sir !!
As an electrical engineer that loves electronics your explanation is spot on. I have never heard the process explained better .
Great explanation. Your step by step approach leaves nothing out and is presented in a logical way that makes so much sense. You make no assumptions of your audience's knowledge which is helpful for novice or expert alike. I am keen to watch more of your videos.
Wow. Thank you. I really appreciate it. Craig
Fantastic! If only my science teachers were as good at explaining things as you are.... Thank you!
Hi. This is probably the best electronic video I’ve ever seen. I came here because the igniter on my gas engine weed whacker stopped producing spark. With the help of other videos I correctly came to the conclusion that the igniter had failed. Still under guarantee I wrote to the seller explaining the problem. They wanted me to return the entire tool’ but I explained I could send them the igniter but their next email stated that they could only give me a refund because the tool is out of stock. In the meantime I purchased another igniter from china, installed it and it creates spark. But trying to start it the engine bucked a little so I decided to check the installation AND THAT’S WHEN I SAW THAT THE POSITION OF THE MINI COIL IS ABOUT A CENTIMETER EARLY. Which to me means that the timing is off. But I wasn’t sure until I watched your video. It’s truly a work of art! Thanx so much for creating it.
Great job! I've known most all of this, separately, for years; but you put it all together clearly and concisely...
I have fitted these coils to older B&S and although I knew the basic idea it was great to have an in depth explanation rather than having the meaty bits glossed over, well done.
Does this type of coil work in an older B&S that originally had points? Using the original flywheel?
A heartfelt 'thank you' for such a crystal-clear explanation. You are an exceptional teacher and your illustrations in this video helped me to understand old concepts in a completely new way. Well-done, sir, and once again 'thank you' for the role you are playing to educate those with a thirst for knowledge!
Best explanation of generating a spark in an internal engine. I never understood all the physics that was happening until now and I am 73 years old and worked on a great many motors. Thank You.
Awesme video guy. I'm an old retired E.E. who works on small engines and needed a refresher course. Thanks so much. It's the best technical video I've ever seen, and I've seen a bunch. Congratulations.
I really appreciate your feedback. Thank you. Craig 👍👍👍
WOW! Now that is an explanation beyond 'Fascinating'. I can't wait for the video that shows how the system of points and condenser works. It's something I never understood.
Wow, I was 100% not prepared for this high of quality. Great information!
Craig, That was the clear, logical, step-by-step explanation I have always wanted to see. Bravo! The animations and actual cut-in-half transformer coil, showing the real life locations (initiator, primary, secondary coils) brought these electronics and physics concepts into full sunlight. Thank you.
As an Electro-Mechanical Engineer teachers in schools should use the explanation video to there first year students in basic electrical understanding ,it's the most simplistic explanation and so informative of how spark is explained with the video seeing is believing....Great Job keep them coming.....and thanks Glenn
Thank you for your great feedback. I really appreciate it. Craig
As a graduate engineer I find this discription excelent. I am trouble shooting a faulty small engine, no spark. I realize the coil is bad but have never looked at the design of a small engine ingnition system. Your description was GREAT. I understood the basics but was not sure of the final engineering involved and you cleared it up perfectly.
You Sir are a genius! I thought I understood the basics of a magneto. It seems I didn’t know nearly enough.
TH-cam should give you a raise.
Cheers Craig
Something that had intrigued me for yonks was how contactor-less ignitions worked, but all clicked into place after watching the vid. Love this style of teaching/learning i.e., why and how.
For my practical’s classes, I attend a Canadian guy who likes a beer, also, a couple of others others too. Great work by all, many thanks.
Speaking as a technical writer myself, this "lesson" was (IMO) very well done!
You’re presentation technique is spot on which makes the subject easy to understand, the level of detail you have included here is just right, thank you. EE Eng.
You Sir are about the BEST teacher I have ever seen . I have been an automotive technician for over 40 years and this is the best explanation of how a coil works right down to the atom! I also wish my teachers had your ability to explain electron flow back when I was apprentice. Thank you!!!
Wow. That’s some of the best feedback I’ve ever had. Thank you. I really appreciate it. Craig
Just awesome. Educational videos as clear as this are incredibly rare. Thank you! 👍
Thank so much. I really appreciate it. Craig 👍
Good job. I also did not know about trigger coil and Darlington pair. As an EE, I suspected that the current induced in the primary would be alternating. I think I now see that the transistors impede the reverse flow. That requires a high reverse breakdown voltage spec on the Darlington, but really shortens the mag. field collapse. As we know, E = -L (dI/dt), so that short dt gives the high V.
Well done Sir! You have taken my understanding of basic electrical theory to the next level.
Mate, if they taught chemistry and physics in schools like you have done within the first 8 minutes, we would have a nation of geniouses. Fantastic presentation. Good on you. Thanks.
Wow, thanks. I really appreciate it. Craig 👍
@@TheRepairSpecialist Hey Craig, you are most welcome... well deserved mate :)
woah, I was not expecting a full blown science video. My knowledge of electricity over the course of 15 minutes just jumped more than it did in 4 years of school.
Never studied this before. Replaced some coils, but I didn't know about the trigger coil. Very good, technical explanation. Thank you!
if there were teachers that could explain principals of science in this manner there would be a lot more smarter people, to run this planet and beyond
there are, and they do. and so, there are.
Holy cow, that was an amazing explanation! Thank you!
AMEN
I clicked this expecting a video explaining how to service the coil pack on a lawnmower. Instead, I got a sub-atomic physics lesson. My lawnmower may still be broken, but now I understand how a transformer works, which is something I've actually wondered about for awhile. Good stuff.
I’m teaching my teenager the basics of a lawnmower and we found the coil pack. I didn’t know how it worked , but your explanation was uniquely clear and properly detailed !
Absolutely excellent explanation of ignition module workings! I thought I understood until you clearly explained it! Thank you so much. Keep these kinds of educational videos coming!
@@davidwillard7334 Dave - instead of the repetitious comment w/o info how about a link to your B&S manual of the 80s ? = more helpful ...
EXCELLENT description of the process...well done.
ABSOLUTELY BRILLIANT. I AM AN ELECTRICAL ENGINEER. THISIS THE BEST EXPLANATION I HAVE EVER HEARD. YOU ARE AMAZING!! KEEP UP YOUR AMAZING WORK!!!
Being an electrical technician myself this is very informative. It refreshes us. Tnx keep it up
This is one of the most amazing videos I've watched on YT. I came here to see why my go-kart was not getting spark and got a whole physics lesson!
Wow. Thank you so much for your kind feedback. Craig 👍👍👍
Great video and great explanation of how the coil works. Straight to the point, no lengthy introduction talking about the cat, dog, length of the grass or some other unrelated stuff. Thanks
Craig, you do an amazing job of explaining how things work, and of making great visuals to go along with them!
Great video. I do small engine repair. When somebody asks "what could possibly go wrong with a coil?", I can explain how complicated the operation really is.
The operation is complex, but the coils are simple. If each coil has the proper resistance end to end and is not shorted to anything else, such as primary coil to secondary coil or ground or to the core, then it works just fine. Same with transformers.
@@Hopeless_and_Forlorn This gives meaning to the numbers when blindly following u tube directions to check resistance.
@@shoechew you can't really test 100%. Insulation inside might break down under high voltage but not at 9 volts or whatever the multimeter is.
@@redtobertshateshandles Which is why they make meggers.
I’ve been an electrical technician all my life, and taught for the last 3 years. Most people who explain electrical topics to the average non-electrical tech skip over the basics leaving the poor student puzzled about what electricity and induction actually is. This was a great explanation of the ignition system and an introduction on how electricity is made, transmitted, and works in everything we use.
Thanks,
Fixed my no starting problem on my John Deere
garden tractor.
Inside the rubber boot that
slides over the spark plug
the metal plug wire right
angle connector had
broken.
Only thru the Grace of God
did I discover the problem.
The spark plug wire pulled
free from the boot.
