CDI unit testing. how to test bike cdi on multi meter. motorcycle cdi unit testing on multi meter

Here in this video you would learn how to test a bike or motorcycle cdi unit using a multi meter. CDI unists are very common now a days on motorcyle. CDI stands for capacitor discharge ignition system. It is very important to know and properly test the cdi box before replacing it in case if the bike is not starting.

I agree it's nice to find somebody that can explain how it works from point to point and also show certain values you must have or you don't want thank you very much

[@regan1127]

Thanks for the quality lesson, very very helpful. It's always good to learn from someone who actually understands what they are teaching.

[@jasonnagel1931]

how much will it cost for you to rebuild my ktm cdi?

[@user-vg4ex6hu1m]

Thank you, you help me out so much man, thank you, thank you.

[@justinparrish2192]

Finally someone that knows how to break down the functionality, operations and how to test them on a CDI box. Thanks!! Your newest subscriber as of today.

[@brianb5779]

Cant agree more!!!

[@jacksonjaime3525]

i guess Im asking the wrong place but does anybody know a method to log back into an instagram account?? I was stupid lost my login password. I love any tips you can give me

[@maddoxsam9882]

@Jackson Jaime Instablaster =)

[@jacksonjaime3525]

@Maddox Sam I really appreciate your reply. I got to the site thru google and Im trying it out now. I see it takes a while so I will get back to you later with my results.

[@jacksonjaime3525]

@Maddox Sam it did the trick and I now got access to my account again. I'm so happy:D Thank you so much you saved my account!

[@shannonstabler8925]

Very educational someone to show you exactly how it works and step by step how to test it very helpful I wish I had seen this video before I went and ordered a new cdi

[@littlebittybert]

Thank you for this good explanation of what I've mostly always seen as black magic! Thanks to you, I got the bike running again. My ignition all tested out good, it turned out to be the kill switch!

[@beausdadbeausdad3659]

Subbed, very good info in a straight forward manner, thank you for your vids, keep them coming, ive been workin on bikes about 30 years and the only CDI's i have repaired have all been a simple capacitor failure... replaced the main capacitor and they spring into life, your vid on the other components inside has opened up a new Avenue of learning for me, thank you sir 👏🏻👏🏻👏🏻

[@cker1924]

I agree. It's an excellent teaching and demo. Very practical and thorough. Thank you!

[@petesquickfixdiyshortautor1218]

Best video explaining the CDI and I highly recommend watching if you are a mechanic and want to know HOW ELECTRIC COMPONENTS WORK this is the video for you. Thank you for the complete explanation. *****

[@odysseus2843]

Very goog explanation. Down to the components. You really know basic electronics. Thank You!

[@SheepHunter9780]

WOW. That was the BEST description I've found on just how the CDI boxes function. Thank you very much Sir!! You are A Very good Teacher.👍👍

[@dan1565656]

Brilliant, really informative. Always wondered how CDIs actually function. Thank you. Knowledge is Power!!!

[@DavidAndBeverlyShumate]

Second that! Thanks and God bless! ❤

[@MixPickle404]

thanks, brother you saved my money and life thank you so much electricians nowadays charging a lot of money on just detecting the fault

[@antonygitonga8672]

Finally I have a good idea of what CDI is all about.i would really love to learn more about motorbikes.i want to be a proffesional bike repairer.thankyou for the insight.

[@tonyden1339]

Thank you this video was very helpful. I am checking a Denso unit for a Suzuki GSG650, a bit different but I found continuity, so will pursue this and hopefully have my bike running fine again.

[@petermaclean5533]

Yes, you are correct, the bike Alternator, put out like 3 phase 400 volts, love your diagram.

[@radpaul2574]

Thank you for your video. i thought my cdi was bad, but your video and my testing shows that its ok. I still have intermittent spark to still troubleshoot. The coil checks good. but not sure yet on rectifier or maybe crank sensor or bad wiring on my 150cc Lifan

[@yash-vd3bf]

My activa is return from two mechanics without repair due to high repair cost and non releavent expenses now I am sure I will repair my activa at home Very useful information for me in dentails. I have analog multimeter old type but still it is working and it is useful today also Thanks

[@buddylove8225]

Thank you I really enjoyed your lesson I'll be applying it tomorrow.

[@seanmulvaney5607]

Great knowledge & I love how you talk about your knowledge and how you’re basic all knowing in such. A. Matter of fact ways then Proceed to explain how he used to make Them from scratch which nobody has ever done.which noone would ever expect someone. To. Sssay that

[@babygirl8181980411]

VERY informative, and simple! Love it

[@LeadedAsbestos]

Thank you for the video. I need to make a homemade DC CDI for a motorcycle. I'm trying to understand how DC CDI alter the spark timing. Some of them have two trigger coils, one advanced and one at TDC. Somehow the CDI box switches to the advanced trigger at a certain rpm. Other designs only use one trigger coil and they advance the timing as rpm increase by some electronic means. Do you have any videos explaining this? Is there a book I can read? I really want to understand how that works.

[@PuuhisPete]

Great 👍 Finally simple breakdown

[@dustyduvall9577]

Very well put together video extremely helpful

[@nicolec7290]

Thank you very much. I have a 1979 Yamaha 250cc snowmobile. Is there another cdi box I can use

[@ingo_8628]

At minute 5.35 i understood that this is for the AC-version, but i have the DC, you should clarify this in the title.

thanks from Libya 🇱🇾

[@ununitedstateofhysteria8792]

How are things over there in Libya? I hear it’s bad

[@Johny40Se7en]

Nice explanation. 4:33 So basically, that constant "On / Off" thing that's happening in that cycle is a similar thing to how an old distributer cap works that older carburettor engines of cars use?

[@LeoSkeats]

Thank you for your video! Helped save me from a bollocking from my boss😂 PS New subscriber from UK from now

[@Konk005]

My CDI box looks exactly the same but has a seperate wire coming out of the bottom left of the box. How would I test that wire? I'm getting no spark, I've ruled out plug and coil, now testing CDI and next I will test the stator. I hope it's not a wire somewhere. They're tied up in factory wire harnesses and I will likely cause more issues if I have to cut in and open up all the harnesses so I'm hoping my issue is just a part I can replace.

[@srihits4113]

Very educated one, thank you very much

[@ArunPremkumar5]

Thank You!

[@danteskl720]

This is the best video I've seen for understanding the cdi. I can now apply the basic concept to a cdi on larger bikes. Could you do a video for larger CDIs, please? On a bike with 2 coils/sparkplug, there should be a ground wire and two ignition wires to the coils plus the pulse wire for a total 5.. But what are all the extra wires for? (In my case 4 extra wires) Temperature sensors, kill switch? I'm confused. Online wiring diagrams explain only the color codes, not the function of each post. Thanks

[@JahanZeb1976]

I'm sorry as such bikes are not around me here. If I'll get a chance, sure I'll do video on such cdis. Best wishes.

[@user-xl7ms7zj9p]

Have you ever fix CDI for XV400 Virago?

[@rajsudhee9252]

Your video very useful for me

[@erikburhol1585]

Hos would you check, and which point is what on a cdi for Husqvarna 510 2010?

[@padraiggalvin2807]

Thank you so much for sharing this great knowledge. Its useful to test them if a quad or bike isn't worth fixing. One question is how come the current flows back towards cdi unit to the (+ plus) of capacitor instead of going to coil and then plug.??? Like current from a DC battery goes from Positive to negative

[@andrewt3797]

Current actually flow negative to positive. It is the movement of electrons, not protons.

[@guitarman_3693]

DC electrical - current flows from the neg. to the pos. as taught in eletronics theory the electrons move thru the depletion zone to the holes. and it's proven in application, that this is what happens. the confusion is the fault of a long ago guy that was believed to be "cock of the walk" & "told" the eletronic community, that is how it is, so they printed hundred of books & taught this for years, until it was disproved. so the fix was ; the books, schematics, ect. was called conventinal current flow. which aligned with thier system. a lot of teachers & books will say if it is actual current flow or conventional. as a student of electronics , one must do the inversion in your head for hands on field applications

[@Kermssss]

What about a 8 pin cdi does that only have 2 grounds or will anymore then 6 pin have 3 grounds ?

[@Richard_Gobbler]

What voltage should i be reading out of the pulser coil circuit? Green and blue wire

[@marktippins]

The diagram shows the pulse trigger connected to ground, should this not give continuity when testing pins (9:08)? My CDI has continuity to ground via the trigger or alt coil, not sure which one....Or am I reading your diagram wrong.. Thanks

[@koolkruzer2001]

Very good video. Love how he explains what each terminal is and what it does. Especially love how he kept poking and jabbing at the silicone! 😂😂😂

[@MrmachineELF]

Very good explanation . I know engines but the wiring always gives me headache 😂👍🏼👍🏼

[@JahanZeb1976]

Hope now you could easily understand the wiring.

[@randalallen5792]

Guy knows his Stuff.

[@JahanZeb1976]

Thanks sir

[@2daredevils765]

Hello. I am currently trying to fix my son's speedfight 2 LC 50cc scooter. No spark is present. The wiring loom has a 5 pin CDI fitted and also the original 8 pin dellorto CDI/oil pump unit fitted. The bike did start when first purchased, with difficulty. Any ideas how to solve the issue?

[@janosturi7264]

Nice job. Thank you sir.

[@ukaszpacek2761]

Hi. Is there a way to tell which CDI is AC and which is DC type? Just by measuring pins on CDI? They very often not marked and even sellers don't know what they are selling.

[@Kermssss]

So should there always be 2 grounds on every cdi ? If you hold the terminals on the 2 grounds will it beep & is that normal ?

[@JOMaMa..]

Great video !

[@twist_a_g]

I love you 🎉 thanks so much grate video

[@ateam7039]

Should there be continuity between the 2 ground wires on the dc cdi?

[@allensnook7760]

I get it now there sorta like the old points and condensor in old ignition sysyems only now done with micro processor parts,cool.snooky pa.

[@arunp6226]

Thank a lot

Very nice,the elusive cdi box,is it good or not,thank you!

[@corbana4743]

Thanks brother Great video

[@bunglingbiker3977]

My bike is sparking several times throughout one stroke, not just at TDC, and causing backfire etc, is this the cdi?

[@feero9680]

i have reading of 500 ground and alternator. is it considered no continuity

[@jackofalltrades3654]

Thanks man

[@shaikhazhar5404]

Very nice video thank you..... please explain if hard material (instead of soft silicon) how to remove by providing heat. Pls share new video explaining same

[@JahanZeb1976]

Yes. Good comment. I will bring videos on that too here on my channel.

[@Kiran-nb5xi]

Great sir you design and convert point bike to cdi bike

[@pennyroberts5144]

Is that CDI for quads as well

[@Kebekwoodcraft7375]

Very nice 😊 Do the CDI are the same for 50 cc to 600 cc or the engine size have different AC CDI 😊 Thanks ☺️

[@ardakaraoglanyan6319]

Hi there, i don't know if anyone sees this comment or not but would like to give it a shot. I have an AC CDI with 50cc scooter, turn key no light, after starting scooter lights gets on and pretty low with flickering unless i'm giving gas which speeds up stator and in that way gets bright... That cause my head light bulb pops every couple of month... Is there any way on wire configuration on my CDI to change all lights feeds from battery rather than stator? Thanks in advance!

[@seriousvidness]

How does the engine shut off? You referred to a "key" terminal. Do you cut power to something or ground one of the terminals to cut the spark?

[@JahanZeb1976]

You are right, a ground is provided to CDI point which is input to the CDI unit. Means the input power is grounded to the CDI through ignition switch which kills the ignition when ignition w switch is shifted to engine off position.

[@juanpierrestrydom3646]

Hi there guys, my tl1000s just cuts out when im riding it. im not to sure if its my cdi box, my fuel pressure, or a sensor? any help
