No Spark ATC, ATV, UTV, or Pit Bike, $20 diy CDI fix, Step by Step Build!

[@Terinjim]

I ran across your video, and like I said to my neighbor, "bad grounds can make you run-a-round," it'll cause your machine to misbehave and not do what it's supposed to do (No Spark). I appreciate your clarity and will show him this video on creating a pit bike. He bought several repair bikes to repair and sell. It's new to him and a good learning curve, so maybe this will save him alot of aggrevation trying to figure it all out. Thanks

[@YouAreLoved1216]

I have watched probably close to 30 videos trying to fix this....best video by far!! Thank you!!

[@MOVIE7TUNES]

I look you up every time I have to explain spark in a bike! Thank you so much!

[@MOVIE7TUNES]

Over the years I've came to your channel over and over again! Your my teacher of choice to direct others to your excellent instructions. Thank you again Harvey!

[@ML-ks2lj]

Lol love the no BS attitude. "Go take a nap"

[@stevegreen7960]

That worked amazingly. I was 2 days away from swapping my 200 es Big Red

[@supertedogpriken]

Hei Harvey. Thank you so much for making this so easy to understand. Wiring has always been a real big no no in my book. but you made all of this look so simple. I watch a guy do this to his old Husqvarna 430 two stroke some time back, but when he did it i just sat there scratching my head only understanding a 1/4 of what he said on his youtube video.... And now a can build myself a harnes like yours and always take it with me when looking to buy new(old) bikes, Thank you again for making this so easy to understand Harvey. Greetings from Norway.

[@rickmath]

Just wanted to let you know I have been watching many of your videos and I have a chines ATV that had no spark could not get to spark ran battery down 3 times trying to start over heated starter just wouldn't start! Then I remembered you built a portable cdi, coil, power all in one "box" that eliminated the bike completely . I watched the video again and rewired the bike according to your "box" and 2 cranks and running ! Thank very much I was getting close to junking it !!! Many thanks and my grand kids thank you also!

[@eliasdeleon9424]

You have just helped me understand when 6 other vids could. Thanks for putting it in perspective for me to understand sir.

[@LewisMowersandBoats]

Brother I don't Think that you could explain it Any better than that great show 👏

[@jbh.6257]

Great walk through !!! Do you have a video on how to verify if each component works or not? My atv was running and just rebuilt my carb but now lost spark ?? I assume I lost a ground somewhere or have a bad coil/CDI?

[@davekimbler2308]

Well Harvey - it’s me again but ... I have great news ! You have been an excellent teacher and in my deafness I somehow missed you say ( everything has to be grounded ) so as you know I’ve been pulling out my hair for 3 weeks and still no spark until the light 💡 above my head went off and in the middle of the last night I went back out to my shop and made grounds for everything! Well I kid you not I HAVE SPARK ⚡️! So thank you very much for putting up with my constant questions, I just wasn’t getting it . This video was by far your most in depth as far as the pit bike harness. Thank god there’s people like you to help old farts like me out when there stumped 🤔. I’ll always be a supporter of you and your channel!

[@PauloOliveira-im7us]

Thanks for the info.!! This video shines a bright light on a dim situation!!

[@jimDseries]

Hi. Fantastic informative video. Can I ask how do you know your pulse generator and stator coil are good ? how do you test them ? Regards Jim.

[@alfredotavarez4701]

thank you for the video I understand it now but I have a E-ton Viper 90r and it has drive neutral and reverse if I wear to wire it like your video will I still be able to put it on Drive? I have no spark as well and trying to get it ready for my son

[@michaelhawkins3810]

GLORY TO GOD!!! THANK YOU!!!

[@davidl7062]

Hi Harvey this is Dave looking for a way to hook up a different CDI box to a 500 Suzuki quadrunner 2000 model is there any other universal CDI could use or a cheap replacement

[@bradbishop2459]

Hey harvey thanks for the video,what would be the process for a two cylinder? My CDI ECU box 9 pin for my 1981 Yamaha virago 750cc has been discontinue is there an after market one I could purchase???

[@wandajames6234]

Blue/white-- from pickup coil that sends the ignition signals as the flywheel outer magnet passes by it. The red/black is from the excitor coil on stator. Would be so great if the language was standardized. A lot of confusion could be avoided but everyone seems to call things different names.

[@brunostank]

can this work on a kawasaki 440 ac ign sys. since it fires a spark plug. also can you hook up dual cdi sysytem with these kits

[@daveydave9884]

Hey Harvey What if I have two wires from the pulse generator and none of them go to ground ? They go to oem CDI and I tried one the meter to ground but it seems it only pulsed using both wires ? What would you recommend?

[@weechitamex]

Harvey Spooner : THANK YOU FOR SHARING YOUR TELANTS HERE SIR . BEST BLESSINGS .

[@maxamhomerepairAndatvrepair]

I forgot to tell you I used this system of yours on a Chinese bike that had a nightmare of wiring harness and I used your system worked great thanks for the information

[@calebfranks2468]

Most informative, easy to understand video EVER!! I thank you Sir Greatly

[@noogo50]

Hi, great videos, just got a tao tao.. quad did run before. Had to change starter clutch/flywheel. Now I get Little to no spark..so it won't run.. could the fly wheel be different with the magnets? It will throw a occasional spark but its not that strong when it does..

[@erikletham4944]

Hey question you seen very knowledgeable on these engines im in a stuck place got a lifan 250cc twin cylinder atv no spark think iys cdi but hers the shit part its a double coil setup single cdi 6 pin ac. Can I run double cdi packs off one trigger wire as the cdi box for this is non exist Thanks

[@travisestes6217]

Hey Harvey, your videos really helped me get going on getting a 90cc ATV wired up. I've got everything wired up correctly and confirmed all my grounds. Left the charging system out, powering the starter directly from booster pack. Getting volts out of CDI lead to the ignition coil. CDI light flickers when the starter is turning and reading about 20v supply to coil but not sure what that means since it operates off the pulse signal too. Getting no spark when grounding the plug and turning the starter with booster pack. Tested the spark plug is good in another engine. I've used two ignition coils could and both tested good with about 7k ohms across. I would assume everything is good up to the CDI since the CDI is giving power when the flywheel turns. Don't have any interlocks or kill switch wires up. Any ideas?

[@charlesbwalker2009]

Linhai 260. What should pick up coil out put voltage be mine is .2 Two tenths of a volt AC?

[@Captainkleen]

I bought a 2 stroke kids ATV for my grandson and I thought I could get it going. It has a GY6 long case but the oil is separate from the gas. He told me it was the carburetor and had a new one. He told me it wasn’t electric start and it is. The wiring harness was all hacked together and when I put the new carburetor on I decided to pull plug and check spark No Spark. So I ordered a complete wire harness with the ignition the coil the rectifier the CDI the six pole stator with connected pulsed a blue wire goes to pick up. Now I have the harness hooked up and of course No spark when I put the news stator in I noticed the rust around the drum magneto so I had to clean the rust off I believe that’s why I wasn’t getting spark what concerns me is I have a stNdRd pin plug and pluged it in but I also have blue and red bullit Connectors but I don’t have Ny idea where they go because my only bullit connectors are yellow and black and green and the carburetor also has a 2 pole plug but I’m not getting anything. When I was leaving with it he told me he had it up to 30mph and it might be a 90cc. Every time they give me a spark plug it’s to small my Spark plug is much bigger at the threads. I did some research on it and the Taiwan company is Rely or similar and the engine is a Her Chee just S I spelled it and the CDI I took off is a 2” square stamped metal box there aren’t any slots to hold a CDI or the starter selinoid on the old wiring the CDI and Rectifier we’re screwed into top of rail. I don’t understand it’s all hooked up except the two female bullit plugs from housing the blue and the red unless I have bullit connectors crossed because everything went were it was supposed to except the separate red and blue and blue goes to pick up inside the plastic cover Any ideas?

[@wheelspkruel]

Man I'm getting it now, man thanks I bought a yamaha warrior 1989 and I have 12v but I dont get no power to the starter,no lights, no nothing so I was checking and your videos and now I'm trying to figure out how everything works thanks to take the time to make videos to help other people.... thanks again

[@itsnotbleach]

My 2020 dual sport just completely stopped working with no power

[@wheelspkruel]

I find out cdi no spark so I'm trying to figure out a way to wire it up

[@wheelspkruel]

Ice man check your key switch mine was messup I change it and now I have power

[@billycollins4049]

Does the cdi on my Honda that is above the head not get used if I use a new pit bike wire harness

[@neurozero]

i have AC 6 prong CDI on my unit. i cant figure out where the problem is. can i just change everything to DC CDI (cheaper ). or shout i change everything including stator to make that change. i want to put something cheap so incase i have to ever change anything in future

[@jorgesolis9025]

Could you tell me where I went wrong with my bike I've changed all new parts from stator,magneto, ignition coil, stater coil new spark plug had it going I also switched cdi box to racing cdi box did some adjustments and my stater hit ground and after that it didn't want to

[@peterjohansson1503]

Hi, where did the greeenwhite wire From stator go? Bluewhite go to cdi....

[@Oazm595]

Hi Harvey, greetings from Malaysia. Thank you so much for being a great teacher and making this easy to grasp. It's been a month trying to figure out why my ATV has this ignition firing problem. That advise (at 12.50) regarding kill switch is a great one. That black/white wire once remove, able to resolve my problem. Don't know where it got shorted to ground, but I am putting it far away from the rest. Thanks again for the great content. Subscribe done 👍

[@MatthewWilliamson-v7b]

I have a yellow wire coming off pulse generator, what does it go to

[@HarveySpooner]

Hey Matt! If there are 2 wires coming off the pulse generator, one should go to ground, the second should go to the pulse generator, if there is only 1 yellow wire, it goes to the pulse generator where the blue/white wire goes.... I hope this helps... Thanks for asking!!!

[@jamesr.riverasr.4678]

So… I have an Artic Cat 500 and I tested all the wires and have power at the cdi and have power going to the ignition coil BUT it will not produce a spark to the plug. Where else can I check?

[@davetaylor8055]

This is by far the best video on the cdi and i think im starting to finally get it. The only question i still have is that my cbi module is for a gy6 and the pins are different than what your showing here , right? Can you please show me the difference so i can make the changes? Thank you.

[@camcraigsadventures7114]

hi can i still hav spark with a bad cdi? i was riding, it bogged, then we stopped i shut er down n it wont start now...i have spark, fuel, no smoke, dash lights when key on, she wont turn over......any ideas?

[@Scionofnothing]

hello there, can you give me some advice?my bike has lights, turning signals, the starter motor works(i assume that piece you say in the video its good otherwise it wouldn´t start) BUT the bike doesn´t start anyway. The lcd/speedometer doesn´t show rpm nor kms, just turns on when ignition is on(neutral light is on) i´ve no spark on the plug, ive already changed CDI, plug and the main fuse Any ideas? :/ its a quad like that one too

You said if bike dies wont spark cut black wires to check if its n on and off switch?. I have a 2003 ltz400 suzuki rode fine shut off random n woods got it home now i turn on switch press start 1 spark then no spark and if i flip switch does again 1 spark then none. How can i check to see if its in my switches

[@FloridaBikeSupplyOnline]

Hey, I'm not sure if it has to due with the CGI or the carborator maybe, but I have a 2016 Taotao T-Force 110cc. The idle seems to be good and steady, and reverse runs strong (maybe a putter from the carb or somewhere by the carb) the only problem is drive, it kinda feels like it's in 4th gear or something. No torque, and it also seems like if I only give it 1/4 of throttle it runs okay, until it goes as fast as it will at 1/4 throttle. As soon as I give it more, it starts to die out and sputter. Any ideas would be greatly appreciated. Love the videos, your a genius! 🙂

[@tomyencha1112]

Hi Harvey, your circuit is great but what if I have an AC stator, where does the rectifier go?

Hi Harvey, Thanks so much. My hired help bought a 125 Fly and has been having extreme trouble. Now the bike has ONE spark then goes dead. Let it sit amd one pop is All I can gret. I'm sorta old school and can't remember how I wired the old T/T scrambler to constant loss! Not sure if it can be done on these new bikes. I think I took out the magneto. Question is? can I run 12v to the CVI for a test for spark. Or should I run all the tests from coil backwards Thanks in Advance I live out of the country on a small Island, parts have to be shipped in. A trouble sum deal

If I swap a 2 coil stator to a 6 coil stator with full wire harness would it work on the atv??

Hey Harvey quick question on options for a bike I'm working on. Customer has multiple ppl look at bike 1990 xr80. Primary issue no spark. Adjusted points it was sparking, then Plug stripped out and retapped and fixed. Go to kick the bike no spark.Customer took flywheel off with hammer and now it needs a stator,points everything ignition wise in the case. Magnets in flywheel broke too. Oem parts are expensive and hard to find.are there any alternatives I can do to avoid the cost?
