Simple Trick To Diagnose A Bad Ignition Module (Coil) On A Lawnmower, Chainsaw, Weedeater Etc.

What would cause a warm echo pb 755st blower did

Really good info, Thanks. !!!

What a load of nonsense. What if your engine has points and condenser ignition and the condenser is bad or your points are dirty or not gapped correctly? Your coil could be just fine and still no spark if that is the case. That Briggs he showed us has points and condenser ignition. Very misleading and could cause lots of people grief if they listen to this dummy.

Thank you so much sir I really appreciate you

Awesome thanks for video. 👍

Hola great video Sir! Simple to test! 👍👍

T-Bone, I really like this method.

Happy days, thanks, you sorted out my problem!

I have an old Solo (1975) chainsaw. It has points and no spark. I checked it out and the coil seems to be grounding out the points. With the coil mounted I have continuity on both sides of the points with the points open. I isolated the switch and it's working. I think the coil is shorted to ground, because when I remove the coil and then check the points they work fine and then put it on again, the points are grounded again. Am I missing something, or is my coil bad?

I’m subscribed to a lot of small engine channels and I’ve watched a lot of videos on this subject. Yours is the clearest, simplest and most straightforward instruction I’ve seen. Well done! This also goes for several other subjects - clear, simple and easy to understand. Thanks! 👍🔧

Great vid. Like the screw driver trick. I rarely have a new spark plug laying around. Those are as needed for me.

Fantastic. Straight to the point, so helpfull thank you

Thank you very much. You have saved me over $600.00 today.

Can you help, kohler 7000 idles perfectly.When load is put on engine the RPM drops.

Great, straight to the point, practical info. 👍

My dad got me so many times ,, hold this Son... AIN'T IT JUST AIN'T IT 😜 lols.... I must have been a bit slow,, but growing up around Ol Pops... Scotty got smarter...😎

Great info T-Bone
I like your absolute simplicity and honesty!!!

The presence or absence of spark is not always 100% for diagnosis ...example, a coil may be good enough to produce spark when cold but when engine heats up and coil heats up it may not. I saw this recently on a mower. Just seeing the spark on a cold coil is not always conclusive.

Awesome the way you explain it for beginners like me. Thank You

Best advice and tips on coils. Helped me a ton. Now of to test mine

👍

Great tips T--bone!!

Sir. you only show as how to quick diagnose coil with no spark at all. Please show as how to diagnose coil with weak or bad spark..

I like you small engine hacks.

Thank You’ll 😊

Love the simple tricks and tips especially diagnosis of a bad coil.

Excellent video on easy testing but do not throw out that coil yet especially if it has a spark plug boot like the Honda one in the video or those that are metal shielded because they have a built in resistor that may fail. I believe these style spark plug boots are supposed to have 5K ohms resistance. On three cases over 9 years we have found them to have 10K+ ohms resistance which created the no spark issue. A simple spark plug boot replacement and away we go, great spark at a cheap part cost vs replacing the entire coil.

thats some great advice there n new here from jack

How many hours before I need to adjust the rockers on my generator (Troy build 5000 watts)? Thanks 🙏

I find a multi meter is useless on a modern coil. It can prove it's bad but can't prove it's good.

Great vid

Easy as that… Show me the money! Great tips at the end too 😁👍

Tooooo easy 🤣🤣🤣, another great tip for diagnosing brother.

Well done T-bone!

Great tip T-Bone, excellent when you put these videos out 👍

Great video. I was just sitting here watching “Young Riders” and the head guys name is T-Bone lol.

Preach T-Bone.... yall say it with me... "To Easy "

Great tip.
I ran into an engine, 8.75 series briggs on a toro timemaster, with such a blown head gasket, the oil got around the head bolts, and the head, and the gasket, it isolated the head from the block, and took the ground away, the spark plug would spark against the block, but not screwed into the head, a real head scratcher for sure.

Good advice!

👍👍👍Thanks Tbone

If your a redneck you can stick your finger in the plug wire.💥💥💥

Thanks.

Invaluable advice for sharing your tips with us, much appreciated my friend! Keep them coming as we prepare for spring.

Nice tips there T-Bone, thanks for always putting out some good stuff brother. 🙂👍
Tell Mrs T-Bone we said hey. 👋

Your tips ,advice and videos really help out.

That's the easiest way to check the coil for sure. I didn't know I worked with you

great tips

...great tip T-Bone.....keep the DIY videos coming!... 🙂

Great idea to check out the coil on any small engines
