How to diagnose and replace ignition coil with no spark on your mower.

[@christopherkelley773]

Josh is a very good instructor. Clear, concise, shows things up close and stays right on subject. Not a lot of hemming and hawing during the instruction. Now I know what I need to get my pressure washer sparking. 👍

[@pipi7731]

I agree. Can't beat that line of instruction.

[@borimex5844]

Finally, a video that explains a coil test in detail and with no Bs. Thanks a million.

[@tommensforth8159]

Great video. No nonsense. No blabbing. Straight to the point. Love it. Thanks.

[@alexwells3432]

Excellent video. Straight to the point. No stupid gimmicks or daft music. No drama just getting on with what you need to do. A refreshig change!

[@dalemanly4913]

WOW! Hands down best freak'n no-nonsense no spark diagnosis and fix I've found. No need to look further!

[@damontellegen3569]

Okay ....Soooo this is EXACTLY why there's small engine repair Pros . You knew everything you were talking about. Right down to the PO obvious experience you have, with the business card and the magnet sucking the coil on to it . bravo sir

[@robmiller1808]

Excellent video, clear voice, no waste of time and the detail in the instructions is extremely helpful. Thanks.

[@gergemall]

Thx , new subscriber, I am fixing the exact mower right now. I’ve had it running twice before . Not sure if her kids sabotage her mower and say it doesn’t work so they don’t have to cut the grass . We are going to follow your lead on this and tell her to never let any of her kids touch it ever again. The woodruff key was broken off this time . W t heck. He must drive it down the concrete stairs hahaha

[@BirthrightGaming]

This video earned you a subscriber. Very detailed and knowledgeable troubleshooting tips. Most of the internet is filled with "cleaned the carburetor" or "change the oil". This is the first bit of advice I've seen that goes into the issues surrounding the ignition coil, ground wire and flywheel. Hoping this will fix the issue with my mower. I have a spark plug tester coming in tomorrow. Thanks for the video and most importantly, the knowledge you shared with us!

[@michaelwolf6424]

This is an AWESOME video. I've been slowly increasing my knowledge on repairing 2 and 4 cycle engines. When simple steps lead to improvements like illustrated here, there's an instant learning curve. Well presented. Straight to the point. Well done .

[@gotdeeres]

Your method works if you have a spare coil. You can test the existing coil with an ohm meter. Connect one lead to the inside of the spark plug boot making sure you contact the metal inside. Connect the other probe to the engine block. The resistance should be around 3-4 K ohms. THis test can be done without removing the coil.

[@philliphall5198]

Have you tested a Honda 4 terminal coil ? Trying to figure it out

[@justtinkering6713]

Ohmmeter test doesn't work on my coil. I have two cylinder and one side works the other side doesn't, so I assume one coil is good. They both fail the ohmmeter test, even the good one. Swapped polarity, same thing.

[@mechanuts7191]

So much better of a diagnostics video than even the ones by briggs. This was worth a like and subscribe.

[@WilliamLoney-y8k]

Great step by step video. I replaced the blade adapter, blade, retainer, bolt, carburetor, air filter, oil change, cleaned gas tank, and new fuel. Lawnmower Troy Built TB110 will not crank over. I did remove the ignition module, and i didn't reinstall it properly. I'm going to install the ignition module your way and I'll repost my outcome. Thanks for the help and video

[@rayhitchcock4899]

The clearest and most precise explanation for this ignition problem that I have seen here, thank you.

[@joebarry4669]

Thanks Josh, my John Deere E 140 quit during my last cut. I saw gas in the filter and it would crank strong. Thinking I have a ignition problem, I pulled the plugs expecting wet plugs.The plugs were dry, which surprised me. I grounded the plugs and saw no spark. This is a twin with 2 magnetos. I watched your video and I pulled both ground wires off and got a good spark. I put the covers and shrouds back on, and it started right up. I am thinking I have a bad interlock somewhere or a shorted ground wire. For now, I just have to be careful because I can get off the tractor while the blades are engaged. Thanks again. I didn't suspect the magnetos because the odds of both failing at the same time seemed highly unlikely.

[@user-ex6vp6mb9q]

Thanks for this great video - I watched it once, quickly got my new coil installed and gapped, then the mower started on the first pull.

[@georgebergman9898]

I would like to thank you for the test instrument info to connect to the coil. I’m heading to O’Reillys parts store. Thanks again, I wish more would share there sources, on videos.

[@garyetodd1]

Before installing a new coil, always check the gap first. I just had one where the coil had vibrated and was touching the flywheel. Re-gaped and was fine.

[@kevinw693]

Hell yea...check the gap...when the fly wheels vibrating and I've regaped her... ill roll over an go to sleep

[@jaymazza69]

Thank you for making such a great, informative video! Based on your video I was able to diagnose and repair my father's mower. Same issue as here... bad ignition coil. Followed your instructions to the letter and it runs perfectly now.

[@jmikhael1886]

Solved my issue i removed the ignition coil and forgot to set the gap. Thank you for your great video

[@RandomStuffWithBill]

Got my spark tester no spark off plug, ran thru disconnecting the ground from brake method using tester still no spark so I guess it's time to order up a new igition coil, thanks for the walk thru here crossing fingers this gets us going again :)

[@joseepena8553]

My field of expertise is HVACR, and this video solved my problem... almost replaced an ignition coil and I had a bad ground due to braking system... Thanks!!

[@5gunner838]

Thanks for the vid. Starting new side hustle with first trial. Cleaned old carb, nothing, put new carb, spark and filter, nothing, now I’m informed of an essential part, the coil. Can’t wait to test it now.

[@larrylee6397]

Thank You Josh, mine was a dirty contact, I have sparky back now. Great video!

[@twoyorkiepups]

Thank you. After watching several videos I finally found the one that helped me solve my problem in language that I could understand!

[@edmckinley1333]

Excellent presentation perfectly done... no crazy music... thank you for the video right to the point

[@kevindove3778]

Great job man,... You ought to do more videos, You explain that very well

[@anogoyadagaate8259]

All of human advancement traces to the elements demonstrated in this video - accurate* knowledge transfer! Thank you!

[@ikemac4307]

Excellent video. Very clear and understandable. You have saved me a lot of time and some money. I just had a bad ground wire.

[@joakimblixt8059]

Thanks! You made my day! Your video helped me to find a problem in the switch from the handle ("Dead mans hand" in Swedish) that gave a flickering ground signal to the coil (Random ignition was my problem but now itis solved!)

[@tigergreg8]

These videos are good in case something goes wrong, when you type in YT search, you get helpful videos like this. 👍

[@franknorton8140]

I appreciate how you demonstrated on how to diagnose now back to my garden tillet

[@RandomStuffWithBill]

Thank you for this video, I have done all the basics new plug, oil, air filter but I cannot get my unit to fire up and start, this is going to be my next test, already ordered the spark plug light thing on amazon, hopefully I can get this running again...

[@nut3557]

Must agree Josh that this is an excellent video. Have a JX 75 John Deere 20 years old walk behind in Australia. spent over $500 doing it back up because they are so good but suspect the coil is stuffed. will now test but the coils are over $200 in Ozz. Thanks for this.

[@jerryspencer7916]

Thanks Josh for your very helpful video. The spark plug tester you used takes all of the guess work out. With or without the orange spark light you know without a doubt if the ignition coil is working. Thanks again. Jerry.

[@paulm3481]

Great video very clear and right to the point. Thanks again just replaced my coil.

[@RobbiRocks]

Great info here &Thank you for having No annoying back ground music

[@pipi7731]

Very good video. I always wondered about that gap between the flywheel and magneto. Thanks

[@XenaTheQuadCamBikah]

Excellent video Josh! Your videos have helped me more than once. Thanks 🙏

[@davidsolomon9085]

Great job explaining how the ignición system works , keep up the good work , 😊

[@askoneslkman]

Great explanation of exactly what happens with the coil connectors and wires connected or not for definitive diagnosis.

[@stevenrobnett7390]

I'm about to test my ignition system on my craftsman push mower thank you for this video. I was mowing a clients lawn and I shut off my mower to move debris and it wouldn't start up again. Tested spark plug no spark tried another plug and still nothing so ima be heading to get that ignition coil tool and see if it's the coil.

[@mikebetts3573]

Oh my gosh that is what I'll standing video I have never did any small engine or any Motors at all I've been a truck driver for 46 years I have a F525 John Deere and I can never get a spark hire so lost without my baby deer thank you

[@GHOOGLEMALE]

Fantastic video - So well explained and easy to follow

[@garylandry2638]

VERY GOOD DEMOSTRATION ,. THANK.YOU JOSH !!! THIS VIDEO WILL HELP ALOT OF PEOPLE WITH THIS PROBLEM !!!!!

[@rustynutz4493]

Best No BS video I've seen. Thanks !

[@altbeere6767]

Nice video. I went through all of the steps and still had no spark. Finally found the problem. The cable from the starter cable was too long. It wasn't disengaging the kill switch where the grounding cable connects to. Once I shortened the cable (search on "How to Adjust Lawnmower Cable" on KZbin), the lawnmower started on first pull.

[@YouMadeMeLawn]

I needed this vid…hopefully this will help me diagnose why my mower has no spark…thanks!

[@alethiasanchez4828]

Excellent Video presentation Dr. Phil

[@cbreezy1322]

Man I've replaced the fuel line, carburetor, spark plug, cleaned the head, replaced the gasket and nothing. Started fine until one day the recoil snatched out of my hand. I unplugged the plug and reached under and spun the blade around and even sprayed some penetrating oil. I'm kind of knew to repairing these so excuse me if that sounded like a waist of time. Just trying something to see what works. The last thing I'm on is that ignition coil. After that I'll probably have to let it go. I took the coil off and just screwed it back on. I'll do your card trick and see if that helps something. Thanks for the video

[@metalinmotionshop]

If the recoil snatched out of your hand that’s usually a sign your flywheel key is sheered. I have a video on that as well. Here it is: How to replace flywheel key on lawn mower kzbin.info/www/bejne/nIu3fJyviKeJeac

thanks for solving my problem, very good instructions. thumbs up!

[@Iaapwm]

Awesome, Much appreciated from Lismore NSW Australia

[@greghayes9118]

The only thing you didn't mention is if like you are located near salty air, a build up of rust can form on both the magnets and the coil contact face.

[@Ragnarou812]

Great video! I suspect my coil is the culprit. I check him out thanks to your video! Tom

[@jamesmyers2087]

Very pro video. Trying to get a BnS 1150 going for my shredder mulcher.

Clear. Very well explained and to the point. Thumbs up !!!

[@karlschwab6437]

Very good info and video. I have collected 3 newer lawnmowers and have them in my barn; none have any spark. I am wondering why coil failure with these small engines is so common? But, in seeing this video, maybe it isn't the coil, but I'll bet it is. Thanks again.

[@Buck2901]

Fantastic tests, thanks for sharing.

[@geze2004]

Nice. Great idea to use a drill to turn the engine.

[@apr2499]

This is an excellent video! Thank you for making it!

[@Mike-ig2zq]

Another great video. Thanks.

[@SatellaPower]

That trick helped us rule out the ignition coil being faulty, and it was nothing wrong at all with the unit. It was just a reassembly issue! smh! every thing worked great.

[@jessesanchez2648]

Awesome video I enjoyed the information on it, thxs.

[@holdemNE1]

Excellent video. Thanks for posting.

[@phillipdavis4507]

Back in the 70's, I had to replace the fly wheel! How to test; if the fly wheel can hold on to a LARGE head screwdriver, then it's good, if it won't, then replace it. Point is, it CAN happen. 😁👍 (Before electronic ignition, I almost never had to change the coil, then it was usually from some kind of damage )

[@hectorportillo1906]

Thanks! Your videos are very very good!

[@ariela51]

Would you happen to have a video on how to replace the ground wire? Thanks!

[@SusieMike]

Good concise and to the point. Thanks

great video and well explained

[@nickhilinski7646]

Thanks for the video on this I have a Craftsman lawn mower like that. I've tried but you showed on and it still doesn't start I still have to use starter fluid to start it up do you have any other suggestions on what I can try thanks a lot you have been a big help

[@reyreyna1068]

Wow good video learn something today great job bro. Thanks

[@joshcordell6814]

Very well done video. Much appreciated!

[@philliphall5198]

How about a video on testing the new style Honda 4 terminal coil ?? Can’t find video on it

[@assadanglangsub6460]

Easy and quick to understand. Thanks

[@truemanrep3267]

i just put a new tip on the secondary. one that is a crimp style not a coil of steel with a spike pocked through the insulation. hoping that it contacts the wire in the high voltage leed. That starts to arc and burn the spike end.

[@customcutter100]

You could also not have spark due to corrosion between the coil and the mower frame.

[@beegekhaos3171]

Awesome video! Thank you so much!

[@Newlinjim]

Good job Josh.

[@algarbarino8538]

Josh Great video. Does the flywheel magnet have to be set right on the coil

[@brianmurphy2912]

Thanx, big help on my cub cadet.
