I just replaced my ignition coil on a kz440 and it still didn't work. After about 1 week of troubleshooting I saw this video and found out my new ignition coil failed. This video relieved me of a huge headache. Thanks for the troubleshooting guide! 👍🏾👍🏾
Thanks for adding a real world experience. If I had a nickel for every time I've heard someone say "I just replaced the whatever with a new one, so it can't be that causing the problem", I'd be a rich man. Yes, things can be defective straight from the factory.
GREAT video! My RM370 pops and snaps and won't pull under load, and I saw .5 ohms on the primary side. Double checked my meter and your method on my good running GT550 and it showed 4.5 just like you said. So now I know what the RM needs. Thanks for posting this!!!
Gonna try on my quad that went down a week ago or so. Had spark after replacing the ignition switch. After which I simply removed and cleaned my batt. cables and terminals, placed em back on, and did not have spark anymore. A bit worried about throwing loads of money at a diagnosis, so purchased a multi meter today. No experience using one but there are luckily some informative vids on here. Thanks man !
Awesome video. I'm rebuilding a '92 VFR750F that has no spark. I was about to blindly start replacing coils but it turns out I was testing them wrong... I'm sure one or two are bad, but this gives me an excuse to go play with tools again. This helped a lot, thanks!
Thanks man FINALLY someone that gets to the point and just stick to main points of info I'm tryn to find . Omg I can NOT understand how some people can make a 25 min vid of screwing in a lightbulb
thanks for posting this video. I am working on 78 DT400 that is giving me all kinds electrical issues. Ran last Sept. but refuses to fire now, took the spark plug out and held against the engine but no spark. Will now try what you have shown here. Thanks again.
sometimes the spark plug cap fails - the coil could well be fine - best to unscrew the cap and test that as well or test the HT lead as that can also fail
Really appreciate vid. Put over $300 bucks into my sportsman with upgraded RMSTATOR ignition changed stator/pickup coil voltage regulator used your test and it was the coil. $29 bucks but I got it free because it was still in warranty. If I'd only seen this vid. earlier. Thanks will subscribe.
+OutlandRiderz damn. I'm getting to be in the same boat as you. glad I found this video though before I started throwing money. First I need to get a multimeter >.
i know a good multimeter is necessary (and mandatory) on some levels but i prefer using my fluke automatic multimeter...if i need to technical i just switch to the other probe input on my meter
Thank you! Brief and to the point! Your hands were not in the way, like most of these people trying to make a video. We could see what you were doing and didn't have to listen to a lot of time consuming nonsense! Excellent dude!
finally I found somebody to know if they were done thanks man you know what your doing but call you know what you're doing with the video thank you wanted the best instructional videos I've seen tonight
My brother this is 8 years after you posted it and it still helping people out cuz it just helped me at least rule a few things out I've got ohms reading 4.2 from my coil I believe it's the primaries I was checking I go to check the secondary the way you did my meter did not change at all but then again I also tested the volts going to it nothing not sure if it's homes won't go ahead and run through both to check homes and voltage going to it so anything at all either yep just checked no ohms no volts going to it
NIce Work. This is something you can commit to memory. (3-5 or so primary 10-20 grand secondary) and have an fast troubleshooting step that diagnoses a major component/culprit in the no-spark scenario.
Hey don't go throwing away your coil just yet, it could also be a bad HT wire connection with the plug, or the lead with the coil or just a bad wire. You can test this by disconnecting the HT wire and retest where the wire connects to the coil instead of the plug end (or just by pulling around a bit checking for loose connections).
Good video was helpful thanks, I did the tests thought I had a rotten coil but it was the end cap not on properly make sure you check that first or you could be throwing away a good coil
Thanks, man 👌🏼 I finally found the damn problem, that I've been trying to solve for a couple years, now. One of my spark wires was badly worn, not even touching the coil anymore. Cheers man👍🏼
Great video. I'm working on a 73 Suzuki RV125 that lost spark. Coils are available, but, extremely expensive. You probably just saved me $125.00. Thanks!
You may also use a mega ohm meter , because as a student of MMI Phoenix AZ they taught us that resistance really doesn't mean it's a good reading. But a maga meter will create an open if it is there at all
great video! helped a lot, thanks. if your testing it on a smaller bike with no battery do you need to kick it with the probes in or will a number come up anyway?? thanks
this helped me out a lot. thank you. I tried this and it confirms I have a bad coil. I'm confused at the moment because the bike starts, can the bike still start if the coil is bad? one of my mufflers gets hot and one stays cool to the touch so I was assuming the bad coil isn't firing up on the cool muffler. any info is greatly appreciated. thank you in advance.
Fyi. This only works for single coil bike. If you have 2 coils. You check the secondary by inserting the leads of the multimeter to the both of the spark plug wires. Hope that make sense.
I just ran this check on my 2001 750 ACE. My secondary reading was the same as youors. I have spent way rtoo much money trying to figure this out. I will check the wires, then replace the wires or coils. Hopefully, this will fix the problem.
Love your vid brother. I've done everything to this motorcycle from carbs, vac lines, plugs, fuel pump, oil/oil filter. The bike starts right up and idles great, it dies upon throttle unless I spray fuel in airbox or carbs, then it will rev normal. Can a bad coil still spark just enough to idle but not rev? Any help appreciated.
awesome video! i have a 2006 pw80 2-stroke dirtbike. I checked all the electrical amd the only thing out of spec was the secondary coil but it was reading too high at 11.6 and spec said the highest it should be is 8.6 Does this mean my coil is bad? It does have spark when i used a spark tester. my compression was good at 110. My carb is acting funny and dribbles out fuel. I have chem soaked it and ordered a rebuild kit. It wouldnt even turn over when I sprayed starter fluid in the carb. Im kinda stuck. Any advice would help!
when trying to start my bike there is a spark at the beginning of pressing the electric starter and when i let it go, but not in between - do you think it could also be a bad coil? thank you for your video!
Would it be unwise to swap out spark plug wire before spending on a new coil? Just sayin, is it not impossible that they go bad as well, or would a good coil pass this test regardless of the plug wire?
good video ,we all know the pain I am currently going to an elec problem on my Kawasaki dirt bike no spark coming from the bike , so I orderd a new coil and if that dosnt fix it I might need a magneto YIKES!!!
I have a motoplat electronic ignition coil for a 70's dirt bike and the primary measurement is 33.1 ohms. The secondary is open (too high), so I suspect that there is a problem with the plugs/wiring. However, is 33.1 ohms too high and an indication that the primary coil is faulty?
An excellent video from a true expert. Thanks for making this quick, to the point and informative.
excellent and to the point. Watched 6 other videos that took 10 -15 minutes to explain and it was still unclear. 10 STARS!!!!
This was great! Short, simple and to the point! Thanks for putting this out. This will help as I restore my 1980 CB750 on my channel!

Thank you, I followed that and was able to verify my Lucas 6v Coils in as long as it took you to so clearly demonstrate the process.
GREAT video! My RM370 pops and snaps and won't pull under load, and I saw .5 ohms on the primary side. Double checked my meter and your method on my good running GT550 and it showed 4.5 just like you said. So now I know what the RM needs. Thanks for posting this!!!
Thank you .. nice to have someone talk English and don't rattle on about a load of crap that makes no sense or got nothing to do with the subject

😂🤣
Thanks for the video and i agree with you final comment. Trying to get my 84 125 RM running. You get my Thumbs up 8)
Thank you for explaining the process, this helped me a lot.
I was lucky, this was my first vid. It's all I needed. Thank you from Western Australia.
Thanks , best vid yet on coils , nice back ground music !
Thanks Man !!! I just checked it on My ct 90 the coil is good ! I think it is the condenser .
Keep up the great vids !
Awesome video! Searched through about 20 videos for what I thought would be a simple answer to find before I found this, finally!
Simple but well shown I'm off to check mine as I have all the symptoms of a bad coil. Thanks
thanks for posting this video. I am working on 78 DT400 that is giving me all kinds electrical issues. Ran last Sept. but refuses to fire now, took the spark plug out and held against the engine but no spark. Will now try what you have shown here. Thanks again.
Cgreat video. Please put up more, you have a great explanation of the problem I’m having
Very well explained for newer bike owners thank you
sometimes the spark plug cap fails - the coil could well be fine - best to unscrew the cap and test that as well or test the HT lead as that can also fail
Best video out there super detailed and quick. Thank you
Great video! simple explanation, much appreciated!
Thanks for the video. Confirmed what I was reading on my coil. Strange coincidence that I am working on the same model CL360!
ha ha, I own a CB360, but I needed to know this stuff for a 6v single coil 1958 Triumph
Really appreciate vid. Put over $300 bucks into my sportsman with upgraded RMSTATOR ignition changed stator/pickup coil voltage regulator used your test and it was the coil. $29 bucks but I got it free because it was still in warranty. If I'd only seen this vid. earlier. Thanks will subscribe.

Short and straight to the point, beautiful vid
Your a Godsend, thanks SO MUCH MAN!! definitely subscribed.
finally I found somebody to know if they were done thanks man you know what your doing but call you know what you're doing with the video thank you wanted the best instructional videos I've seen tonight
nice short price and to the point - you are the man !! nice work.
Outstanding video. Awesome background music.

You can test this by disconnecting the HT wire and retest where the wire connects to the coil instead of the plug end (or just by pulling around a bit checking for loose connections).
Seeing what a non working coil reads compared to a fully functioning one is very helpful, will be checking my own bike for the same problem.
Great info. Another good test added to the toolbox....
Well done! about the fourth or fifth vid I've watch professing to show this. First one with all the details. THANKS!!!
It's ppl like you that make the world turn. Thx bud.
Excellent video...professional made...just to the point. Big tks.
wow you nailed it right quick! well done! some just guess, you made it easy! thanks!
Thank you so much - clear and simple
Great info! Thanks for this.
awesome to the point , showed multi meter settings great vid
thanks for this one. saved me a ton of hassle
Good video was helpful thanks, I did the tests thought I had a rotten coil but it was the end cap not on properly make sure you check that first or you could be throwing away a good coil

Great to the point video!! Thanks
Great Vid & Backing Music !!!
great clean explanation with no added BS
Good video, thanks for the tutorial.
Thank you so much
You fixed my bike.
Great video! Thanks so much!

Great video, i have a Cagiva WMX 500 no spark and wanted to check coil to not just parts change because they are impossible to find!
great video! helped a lot, thanks. if your testing it on a smaller bike with no battery do you need to kick it with the probes in or will a number come up anyway??
thanks
A good and informative video. Thanks.
Thanks, Very informative.
Thank you, I've been trying to figure out my electrical problem on my 71 cb750. Hopefully this will let me know what's going on.
It could have been the line between the coil and the spark plug cap.
Thanks so much. Great video
Great video very helpful and easy to follow
this helped me out a lot. thank you. I tried this and it confirms I have a bad coil. I'm confused at the moment because the bike starts, can the bike still start if the coil is bad? one of my mufflers gets hot and one stays cool to the touch so I was assuming the bad coil isn't firing up on the cool muffler. any info is greatly appreciated. thank you in advance.
Awesome videob! Thank you !
That will sure help!👍
Good video. Very helpful, thanks.
thanks for your time .thats really good things to get my life and experience thanx
great video. thanks!
Thanks for the help!
Great video! Thank you...
ty for the vid that sure helps out alot well done
I did this with a old needle ohm meter. Just looking for an open circuit and voala ... Secondary had no bounce at all... Thanks!
Fyi. This only works for single coil bike. If you have 2 coils. You check the secondary by inserting the leads of the multimeter to the both of the spark plug wires. Hope that make sense.
Please ..can you be more specific. I fdnt follow you.
Good video 👍 now I know how to test my coil
I just ran this check on my 2001 750 ACE. My secondary reading was the same as youors. I have spent way rtoo much money trying to figure this out. I will check the wires, then replace the wires or coils. Hopefully, this will fix the problem.
Thank you so much. Great work!

Thanks. Great info.
My ignition coil earth wire melts when I try to turn over from electric start ... If I kick start it's fine .. do I replace full coil or just HT lead
Great work, thanks. Not the coil, but led me to test the plug wires.....
Thank you sir , will check my coils on the cb360 cause I have no spark on either side.
thank you for this great video
Good explanation. Thank you

Great video!
thanks dude! Yamaha will spark again *_^
great tutorial. thanks mate
ECM controlled coils have a 4 wire plug. Would you know about voltages or resistance on which pin to check ?
Would it be unwise to swap out spark plug wire before spending on a new coil? Just sayin, is it not impossible that they go bad as well, or would a good coil pass this test regardless of the plug wire?
good video ,we all know the pain I am currently going to an elec problem on my Kawasaki dirt bike no spark coming from the bike , so I orderd a new coil and if that dosnt fix it I might need a magneto YIKES!!!
thanks. it helped me with my old japanese thing
Can you do a video on how to test a CDI box??
great video!
Right to the fuckin point ! Great video !! Thanks! ( I have a bad coil)
thanks mate easy and concise...even in american old chap
