I understood everything clearly and followed along perfectly, I had my doubts about the voltage coming in from the coil but when I saw the style (mylar film I believe) capacitor I realized the numbers you gave on the first video most likely are correct, thank you for posting. Reading smd codes is a pain in the arse, 1N4007 we all have, or we should
Best that you understood it well and realized the truth. Such voltage you can measure usig a multimet at some 750v or 1000v ac range preferably an analogue multimeter for the subject job. 1N4007 are the best diodes you can use everywhere.
I'm working on a very old Honda 125 the module has a steel housing, the wires come out of it, and are broken, we can't find a new one. I'm glad you are here to help.
Maybe you can help explain for me. I have a pw80 two stroke with good spark, fuel, and air, but will only backfire. I replaced the stator coil and ignition coil to achieve spark but still no start. Pw80 has no trigger, just one stator coil so the cdi does all the timing? Is my cdi broken or am i crazy??!!!
sir, informative vid ... one question, i connected battery with reverse polarity . Thereafter, no ignition, everything dead when i connected battery the correct way. Normally, the battery has a main fuse located near battery but previous owner was using roadside mechanic who bypassed fuse. So, what component would be affected by the reverse polarity connection? its a 2018, suzuki gixxer, carb model. Many thanks.
I have one on a Suzuki outboard boat engine, thr cdi and coil are together as one unit, its very expensive ti buy a new one 500 dollars us. I was hoping to maybe repair it
Hello, nice video. I opened a cdi unit just like this. I see a 14pin chip inside. Sx195 190141. Maybe an IC. I searceh the internet and i is nowhere to be found. Do you have any idea what this is or an name of code of the same alternative ? Thanx
Such are special code number chips. Sometimes they could be programmable microcontrollers with specially written firmware and uncommon number code on them. Unfortunately they aren't easily available.
Thanks. Ac units are small in size and DC cdi units are usually big 8n size. The wiring configuration tells you whether the system uses AC or DC cdi. In AC system the armature coil directly feeds the cdi. In DC cdi system, the battery feeds 12v DC to CDi unit through ignition switch.
Hello i have a source coil and it is potted together with the cdi box, i am in the process of stripping everything down and will need to repair the cdi box and rewind the source coil then rewire everything the problem is i dont know how it was wired as i had to disassemble it, it is for an echo twin cylinder chainsaw, have you ever repaired a unit like this
This is single phase, I believe about all of them test the same, if yours is single phase this applies. If it's 3 phase however, the testing is different.
Hello sir I have a scooty, Activa 3G not starting. I want to check my CDI unit with multimeter. It has 7 pin. Can you please tell me which prob of it has ground terminal?
Hi Sir, I wonder if you could help me with my Honda steed vlx 400's IC (CDI's component), it's broken.. do you know where to buy it? The IC part number is M6264.. Have called honda & some other companies, but it's all negative..many thx before
by using a throttle position sensor, which is just a magnet attached to the throttle and it activates a reed switch when you open the throttle completely
They are very commonly available and low cost diodes 1N4007. I had taken them from an old board. These diodes are there in almost all 230v operated boards.
CDI is not controlling motor speed. Instead CDI is following speed and providing spark on all speed to the engine. Engine speed is controlled through quantity of air fuel.
There is no rpm limiter circuit on these cdis. Limit comes due to the whole design of the system. Next in some video I will provide details about DC CDI. DC CDI have no such limits. But it needs a battery on the vehicle to make it working.
LearningZone i have a Hyosung sf50 Scooter with an AC cdi That is Limited to 7000 rpm. It has the same shape and connectors as the cdi shown in your video. Best regards
You replaced two surface mount diodes with lead type for thru hole circuit board design. In your repair the diodes are offset from conductive pads on circuit board. This is not a reliable fix as the diodes have 3x mass and are not properly supported by thru holes from vibration on vertical plane axis. They are also susceptible to thermal expansion stresses from the leads. Even with potting reapplied this is temporary fix at best. CDIs are relatively inexpensive and there are no guarantees the other diode that was not replaced may fail shortly afterward.
I have another video on my channel where I explained it's circuit diagram and connections but better to purchase a cdi unit than make one. They are cheap and works well.
sir mene ap kay har chinel per sms kya hay lakin ap ne kabhi jawab nahin dya mene pocha tha kay mere pass 10 amp china batry charger hay lakin is ka main power suply ka mofet phat gya hay is ka number nazar nahin aaa raha kon sa mosfet lagaon 15 din say message kar raha hon lakin ap jawab nahin daty
I already replied you from my other channel. You can check it. Anyhow you can put any mosfet like 13N60, 9N60 or 7N60. These are very common mosfets and you can buy any one of the very cheap. But if mosfet went bad sure you would replace smps ic uc3842 also and check for other bad burned components like resistors, capacitors and diodes.
Hello, it's really interesting video, thank you. I have question. can i used cdi from different motorcycles or they have some differences? For example cdi on Honda transalp and Honda dio look at same, can i swap it?
If they are same in shape and design, you can simply swap them as they are pin to pin compatible. If they have little change in shape and model number, you can replace the CDI with minor wiring changes.
I have a bad CDI that started and idles but when you gave it gas to move forward it would cut out like a reverse override switch, is how it acted, just like atvs that have the override buttons for reverse, so hen you put it in drive and give it gas to move it sounded the same as if you was in reverse with override, so CDI can start and idle but give it gas to go it cut out and that was the CDI as well, thanks for the videos, I wish I was a smart as you are, but hey according to the leftist, we can make everybody the same through socialism and communism, so I guess there's hope that some how magically the Dems can legislate me being as smart as you lol, how smart humans can be to be so dumb at the same time, ever learning but never coming to the knowledge of the truth
Friend this is not a stillen video. On my channels you will not find anything stollen. All is my own creation. The Engineer is also my channel which is Urdu Hindi. You will find many videos on my both channels with different audio and language. This is the reason you are confused.
you have very good content just not good videos. in this video you went too fast when it came to testing. nobody is repairing CDI everyone buys cheap chinese replacement. zoom out little bit and talk slowly showing what the reading is.

Sure. I have complete videos here on my channel about new CDI and complete wiring. You can watch them and get help from them. Regards,
Really wish you could have shown the diode removal and replace!!! Just to see and learn how and what you do.
Thank you, for sharing your knowledge, your experience shows through ,great job hoping to see more of your work.
I like your explanations please keep up the great work you’re helping a lot of us.

💥🏍️🤔Hi, Can you use that CDI or which is the replacement like that can be use on a yr2000 Kawasaki Vulcan Classic 1500cc E3( it has a AC Dual Stator)💥
I have one on a Suzuki outboard boat engine, thr cdi and coil are together as one unit, its very expensive ti buy a new one 500 dollars us. I was hoping to maybe repair it
Thats awsome thank you what tools do i require to be able to repair the cdi units?
Screw driver, pliers, soldering iron, hot air station, multimeter etc.
I have cdi for ktm sx 380 2003 model it's not working can you explain it for me
Any suggestions faulty cdi . I have Mahindra gusto 125 . Plz suggest which other cdi I can use
Which components that arrange and give limit the out put electricity

Such are special code number chips. Sometimes they could be programmable microcontrollers with specially written firmware and uncommon number code on them. Unfortunately they aren't easily available.
Can we upgrade cdi in bike and get more performance from bike like top end speed by improving current?
No. It's just a power flow circuit. If it has a built in speed limiter, the wire can be disconnected or cut.
Salve, video interessante.
Vi volevo chiedere come si fa a sapere se la moto vuole una centralina AC o DC.?
Grazie e buona serata
Thanks. Ac units are small in size and DC cdi units are usually big 8n size. The wiring configuration tells you whether the system uses AC or DC cdi. In AC system the armature coil directly feeds the cdi. In DC cdi system, the battery feeds 12v DC to CDi unit through ignition switch.
Hello Sir, I want make a new CDI for my project, can you help in this regard

No, I never get a chance. You can do it by diassembing carefully the older and do new the same way.
Awesome repair - great job.
Thanks for your valued comment. Stay tuned and leave your great comment on each upload.
Good work bro . Perfect
Any CDI box should have no continuity from the ground pin???
Almost all. But you make sure about connections.
I Love You Sir. You are a Great person.... 😙😙😙😙
Thanks! Do you have an experience with CDI’s for bigger motorcycles, for ex. 500, 600 sm3 - Suzuki, Yamaha, etc.?
This is single phase, I believe about all of them test the same, if yours is single phase this applies.
If it's 3 phase however, the testing is different.
Very Good Video. Thanks where can I find same cdi , I mean what is the factory name ?? It was very
good that it was only silicone in it.
What about the bottom line? The bottom 3 pins should they have continuity
Hello sir
I have a scooty, Activa 3G not starting. I want to check my CDI unit with multimeter. It has 7 pin. Can you please tell me which prob of it has ground terminal?
I'm getting continuity on the pin next to ground pin so the second pin bottom .02 ohms
Great information
Make video on Royal Enfield TCI
Thank so much..i get some knowledge...👍👍😅😋📯
Sir cdi ke opar oil laga hota he WO saf kar den to koi masla to ni ya oil laga rahna zarori he
Brilliant!. Good day sir,Can you please make tutorial on how to test motorcycle ignition coil using multimeter?
How to provide temperature?
Use a hot air gun
Hi Sir, I wonder if you could help me with my Honda steed vlx 400's IC (CDI's component), it's broken.. do you know where to buy it? The IC part number is M6264.. Have called honda & some other companies, but it's all negative..many thx before
how does the CDI circuit board advance the timing with increasing rpm?
by using a throttle position sensor, which is just a magnet attached to the throttle and it activates a reed switch when you open the throttle completely
Can v use bike cdi in scooter
Yes sure. As long as you make proper wiring connections to CDI.
Sir which type gel used for cover circuit ?
clear silicon tube from hardware shop
Good work ^^
You are a stud my man....
Thanks good working
brilliant , thanks for sharing this
Where did you get the replacement diodes? Nice Vidz
They are very commonly available and low cost diodes 1N4007. I had taken them from an old board. These diodes are there in almost all 230v operated boards.
Really good
Thank you for that video
Which bike cdi is this?
This for for very common Honda CD70 and CG125 and it's varients and copies.
@@JahanZeb1976 thanks

CDI is not controlling motor speed. Instead CDI is following speed and providing spark on all speed to the engine. Engine speed is controlled through quantity of air fuel.
Excellent!
