Currently taking Ignition and Starting Systems in A&P school. I was in class today and it just wasn't clicking. Thank you for posting this, I get it now.
Thank you thank you thank you. I just bought a case trencher with a v4 with a magneto and I’ve never touched one before and now I see everything I was doing wrong
Excellent explanation. Came across this video while troubleshooting the Wico-X magneto in my 1936 John Deere Model A. It not only educated me on the tractor application but more importantly, for the mag installed in my ‘77 C172. Thank you very much.
Thank you so much currently working on my power plant FAA written test was really struggling with electrical/magneto Systems your video really help me understand and picture the questions in detail.
Thank you! And I am. These videos are for the classes I teach for Portland Community College in the Aviation Science program. I'm glad some people are finding them useful!
Hi, that's a great video. Thank you! And you mentioned on the video that some pictures are from the textbook. Could you please tell me what is the name of the book?
Good catch! It’s because you ground the mag to turn it OFF. So on the back of the switch, the left terminal (as you face forward), which is labeled “R” for the pilot, gets wired to the p-lead of the left mag. That means that the left mag is grounded to turn it off when the pilot selects R.
Yes, though to be precise it is the RATIO of the number of turns in the primary to the number of turns in the secondary (along with the strength of the magnet and how fast it is turning) that determines the final voltage. That ratio works the same way in transformers, too.
If the spark plug in my lawn mower looked like that last one, I'd throw it out and get a new one. Can't imagine trying to sandblast for extra life on a relatively cheap but critical component.
I'm guilty as charged of using slang there. However, "dogs" usually refer to something that engages to stop movement, and these are centrifugally (centripetally?) activated, so... I'll stand by my centrifugal dogs. Ruff.
Sadly, I'm not up to speed on motorcycles, though I worked on one a bit as a kid. It was very different, at least in how it was built, but the principle is probably similar.
I think this is a matter of semantics. To cause a spark, the current through the primary has to change with time. The faster it changes the larger the induced voltage, hence spark. So the current does indeed change with time (I.e., it “alters” with time).
Larry you are amazing. You have a gift to explain clearly and efficiently.
Thanks! Glad it was helpful.
This explanation is more clearer than how my instructor word it to me last night, thanks you!
Glad it was helpful!
Thanks. This is much better than handbooks from the 1970s that they gave us in class. Lol “it’s a mechanic thing”. That’s adorable. A&P’s ✌️
Extremely well explained. Thank you. I honestly have not heard or seen it explained better anywhere else

You’re welcome! Glad it helped.
Very Good, excellent explanation. I honestly have not heard or seen it explained better anywhere else Thank you.
Thanks!
Thank you so much currently working on my power plant FAA written test was really struggling with electrical/magneto Systems your video really help me understand and picture the questions in detail.
Glad it helped! Good luck on your written. Those tests are really challenging.
'just a GA pilot trying to understand better how his airplane works. Excellent job!! 😎 Thanks!
Glad you liked it! Thanks!
Im repairing an old tvs-90 lownmower....this video really helped me...
working towards my AME license and these videos are bang on. Super super helpful. If you aren’t already a teacher, you should be.

Hi Larry - Thanks for sharing this excellent video on magneto operation. - Jim
Very well presented keep up the good work.
Hi, that's a great video. Thank you! And you mentioned on the video that some pictures are from the textbook. Could you please tell me what is the name of the book?
The book is FAA-H-8083-32A. The AC 65-12A has the same pictures in black and white and can be found the FAA's website as a PDF.
@@Gl4uc0n Thank you so much for your information!
Sorry I didn't see this sooner. We use the AMT handbooks, which you can get for free from the FAA website.
very good
30,500 views!! Youre going to be the next UA-cam millionaire!! I will have to come visit you soon!
Haha! Sweeet! All I need is a couple million people who are REALLY interested in magnetos. Hope things are going good for you, Brian!
@@pccaviationscience6769 Things are! I hot hired at Red Wing aviation flying the Citation Ultra. I start on the 21st March!
Why on a mag switch is the right mag on the left and vice versa?
Good catch! It’s because you ground the mag to turn it OFF. So on the back of the switch, the left terminal (as you face forward), which is labeled “R” for the pilot, gets wired to the p-lead of the left mag. That means that the left mag is grounded to turn it off when the pilot selects R.
Excelente 👍
Gracias.
if the coil have more Turns ,, does that Give it more volts?
Yes, though to be precise it is the RATIO of the number of turns in the primary to the number of turns in the secondary (along with the strength of the magnet and how fast it is turning) that determines the final voltage. That ratio works the same way in transformers, too.
Ummm where is the d2l link to the virual mageto ? And thanky you for the vido ofc :)
He mentions the link at minute marker 8:08, but didn't see it either. Where is it?
Dude is grinding up the spelling typos in the 8083. 😂 glad to see that everyone hate that damn book just as much as I do.
If the spark plug in my lawn mower looked like that last one, I'd throw it out and get a new one. Can't imagine trying to sandblast for extra life on a relatively cheap but critical component.
I agree with you, for a lawnmower. Aircraft spark plugs can run well over $20 each, though, and there’s two per cylinder so it adds up fast!
11:17 Centrifugal dogs? Haha. Flyweights?

how to test a motorcycle magneto
Sadly, I'm not up to speed on motorcycles, though I worked on one a bit as a kid. It was very different, at least in how it was built, but the principle is probably similar.
the original magneto does not need those things and it was a dc magneto ac is not necesary at all
I think this is a matter of semantics. To cause a spark, the current through the primary has to change with time. The faster it changes the larger the induced voltage, hence spark. So the current does indeed change with time (I.e., it “alters” with time).
