How to Diagnose, Test and Install an Ignition Coil When your Chainsaw Won't Start & Has No Spark.
In this video you will learn how to fix a Chainsaw that has no spark. Sometimes the saw will start and run okay until it gets hot and then it will quit and not start until the chainsaw cools.
I will show you how to diagnose, test and replace your ignition coil.

Truly thank you from an Old DAV who’s been pulling on a Stihl for a really long time with no results.. Semper Fidelis

@joshualee1895 Год назад

Great video! Thank you! I think this might be my problem too. I’m off to check now

@rockethound69 Месяц назад

Thank you very much!! I did exactly what you laid out and my old J'red 670 Champ cranked right up after swapping the coil out from a Husky 55. And Semper Fi as well

@oldmanfred8676 2 года назад

Never have seen it done like that before with the scrench to check for spark!👍

You da man!

@thomasgronek6469 2 года назад

thanks for the video. I've had trouble with Stihl coils, and customer service doesn't really care. I have seen several videos, where one takes out the plug, and turns the crank with (Hand drill) high RPM ( in the operating direction) This somehow clears any magnetic buildup (?). I don't know what it does, or why it works, , , but the videos indicate (demonstrate ?) that it really does work from time to time, , ,but of course, if the coil is fried, nothing would help. Much luck, and thanks again.

@aBradApple 2 года назад

I love this channel so much. Always a pleasure to see that you have already covered a topic I’m looking into. That said, the principles involving hot coils works the same across many applications. Good fundamental knowledge for troubleshooting!

@helpinguonline 2 года назад

Awesome, thank you!

@jeff62301 11 месяцев назад

THANK YOU! - it was just my spark plug ! quicker to test & swap out than to drive to the small engine repair shop.

@jeff62301 11 месяцев назад

and it started easier than it has in years , even after having taken it to the repair shop for different issues.

@helpinguonline 11 месяцев назад

Excellent!

@johnclarke6647 Год назад

I had a similar problem with my MS241 C-M a few years ago. It was not a bad coil, but a disconnected bayonet connector on the spark plug wire. I reconnected it to the spark plug wireand it cranked right up. No problems with it, since.

@oldmanfred8676 2 года назад

Sounded good at startup!

@helpinguonline 2 года назад

Don't know if you watched till the very end... but it works great now. Cut that tree down and cut it all up and the saw works like new. Thanks for watching

@oldmanfred8676 2 года назад

@@helpinguonline, I watched the entire vid.

@stewartbruce8902 2 года назад

Brilliantly executed tutorial. No start on my stihl 011av. Have spark, but question if it's strong enough? Other video recommends buying an expensive tester where gap can be adjusted. What do you think about opening the gap on a spark plug and seeing if it will jump the wider space? How large the gap space? Saw has good compression and I feed fuel directly into carb throat. Thank you for your work and guidance. All the best.

@helpinguonline 2 года назад

If you have spark that is probably not your problem. Gap on your plug should be around .020". Here is a video that might help you narrow down your problem: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qsSWMye9r0M.html Let us know what you find out.

@johncollins8304 Год назад

Well that was so clever how to didn't take the whole thing to bits but just slid the HT lead in/out. I've seen other vidos and it looks such a pain, but you've proved it's pointless pain if the HT cap is small enough. I put an inline tester on last night and got RED pulsing in the window! Who knows what that is??

@jdubya54 6 месяцев назад

Bingo. Coil issues when hot. Thanks for the video

@imtruth69 Год назад

Another way to test the kill wire is to remove it from the coil and use an ohm meter connected to the kill wire and ground with the choke/run switch in the run position. If the ohm meter shows no connection to ground then the kill wiring is not the problem.

@dannysingarella Год назад

Great video. Where did you purchase your new coil?

@helpinguonline Год назад

Ebay

@Brian.......... 2 года назад

What happens if you don't have the right gap you did with the card? I just swapped over an entire electric system and still no spark. Would the gap effect spark?

@jwad297 Год назад

of course.

Echo pet 4000 or a Lisle 20700 Spark Energy testers work well . Very easy to use and are fool-proof . 2/23

@kenp133 10 месяцев назад

Hi, Did all this, changed the plug and removed the kill wire and still no spark. Any ideas?

@helpinguonline 10 месяцев назад

If you have trouble with spark it is usually a bad plug, short in the kill wire or switch, a bad coil or an improperly gapped coil. Sounds like you have checked some of these. A bad coil is very common

@jaysoal 2 года назад

Where did you order the coil from?

@helpinguonline 2 года назад

I ordered that one from ebay... Not endorsing this ebay seller but I got it from happy53621_5 (2925) and it has performed well thus far.

@carlodonnell146 10 месяцев назад

I just learned elsewhere that the aftermarket coils often don't work.

@carlodonnell146 10 месяцев назад

It is difficult to be sure that it is making proper contact when trying to do it alone. shouldn't spark a little just turning it by hand, it is a lot of work when you have to put everything back together just to try it.

@donk537 Год назад

@BryanClark-gk6ie 3 месяца назад

So you gave $50.00 for the saw and the part was $9.99 to fix it' you ended up having a total of $59.99 in the saw. I don't think you should charge yourself any $$$ for the labor especially since they threw in a free spark plug.
