I didn't read enough comments to see people trashing him? His electronic projects are great but mechanically - nope! I was a professional motorcycle mechanic for decades and taught at a motorcycle trade school for over a decade. I studied the engineering of engines and associated systems as much as I could from the late sixties. There were no trade schools for motorcycle mechanics until around 1980 (there is actually quite a lot available in print from 1950's on though from basics to advanced ) I have criticised his method of sealing valves plus explained why valve guide removal was wrong (just in case it's me your talking about) Bad advice is actually worse than no advice, it's major problem online. I have even told Bryan Fuller (various TV shows) he should stick to cars as his motorcycle modifications are bad even if not dangerous (although the way overpriced CB750 he built several years ago probably was, ground clearance for cornering had been reduced too far)
When I got a Jawa moped the thyristor was bad. I found plans online to build something like this. 20 years later it still works. Pretty much the same thing.
Excellent video Music was fine and for anyone who knows what they are looking at no narration was needed, but I’d like to have seen the diagram or schematic before you started the project. That way I would’ve known where you were headed. Thanks for the video and I subscribed 👍🏼
Pretty awesome gotta build one for small engines generator, log splitter etc. Nevermind mind all the dumb handwashing comments my hands look like yours and many times worse even though I wash them thoroughly. It just means you’re a hard worker and less worried about having soft lady hands😂😂😂😂😂
@@logicthought25working with agricultural machinery will do that to you. Worked a few years repairing mowing equipment for football fields and golf courses, my hands were always that way. Used to wash them with a mix of detergent, sugar and cooking oil, and scrubbing with steel wool when i needed my hands to be extra clean. Works a charm!
Back in the late 60s I bought an Knight Kit for a (capacitor discharge ignition) I built it and it worked great made a huge difference. I had a hot rod car that had 12 to 1 compression and I had to change or clean spark plugs every 6,000 miles , even using high grade full copper spark plug wires. The only draw back was I could now hear spark noise on my AM radio.LOL
Yes, the trigger refers to the pickup wire, and the ac input from the stator connected to between two diodes.(Black wire)The ignition coil output is also connected to the capacitor.(yellow wire)
Awesome video only thing I don’t understand how to is connected to the points for timing? I would love to understand if this could be done on a 70’s 4 cylinder car? Thanks Bro!!
In general, it is possible, but it may require some modifications to the car's original system and the use of newer tools (such as electronic sensors). Cars from the 1970s typically had mechanical systems, so they need to be converted to a semi-electronic or fully electronic system. However, not with this CDI. This CDI is specifically designed for motorcycles and cannot simultaneously handle the timing for four spark plugs.
Using a CDI (Capacitor Discharge Ignition) from a motorcycle for igniting a kerosene forced air heater is generally not suitable. CDI systems are specifically designed for internal combustion engines to provide rapid and continuous sparks at high RPMs.🙏♥️
Using capacitors has its limits, and exceeding the maximum limit can cause a delay in ignition. If the voltage of the main capacitor is too high, the circuit may not function at all. However, instead of using a 1-microfarad 400V capacitor, you can use a 1.5-microfarad 600V capacitor, which will result in a thicker spark.
This looks pretty cool. I could see it replacing the old oil bath ignition coil on an old engine. Might be more reliable than the chinese replacements.
It doesn't replace the ignition coil, it discharges capacitor into the coil instead of using just the points, I haven't looked closely at it but it looks to me like an electronic switch, not a capacitor discharge unit, because there is no high voltage generator. Usually there is a high voltage generator to charge the capacitor to several hundred volts which is then discharged into the ignition coil. In an ordinary ignition system the high voltage is generated by back emf and 'ringing' on the coil primary.
@@ericwillis777 I've measured back EMF on several bikes, it's usually around 320 volts. Electronic triggering without points is usually called a TPI system (no imagination in service manuals, Transistorised Pointless Ignition, first used by Suzuki marketing in 1970's)
Hi my friend, I had many Dirt bike and motorcycle in the past , now I have four vintage bike; Honda CG 125, cb 250, XLR 250 ,wave 125 . In most CDI, AC, four wires are enough to start (input, output, negative, trigger), but one more wire can be added as a kill switch. Thanks you 🙏
@@Hiranthaperers hi On the motorcycle wiring, find the CDI socket part, the kill switch wire, it is usually a black wire with a white line, and the hand-made AC input, in addition to connecting to the AC stator, is also connected to this black wire with a white line, now if there is no problem with your switch, the motorcycle will turn off by closing the switch.
In older cars, it is possible to replace the distributor with a CDI system. However, a separate CDI unit must be used for each cylinder, or a specialized CDI system should be considered. Additionally, the crankshaft position sensor needs to be designed in a way that ensures precise ignition timing. Overall, it is somewhat complex and may potentially cause engine performance issues.
I have a 50cc Piaggio 2 stroke engine fastened to my bench and use it for performance experiments as a retirement hobby. It uses a combined CDI/coil unit, I would like to fit a 12volt high performance HT coil from a car using the engines original trigger coil. I would like to use a 2N3055 for switching upto 7amps at 12 volts DC. My engine can rev up to 16000RPM using the standard AC magneto. Is there any chance of a suitable circuit diagram in a future video. Many thanks.
Very cool! If your stator coil is AC, you can use this CDI circuit, you can see the circuit and diagram in the video below. th-cam.com/video/GsVEvlaLg24/w-d-xo.htmlsi=EtzoIkc_B4qOZfFy

@@resurrectiongarage1506another popular option is GM HEI but I'm not sure how well the curve matches smaller engines. For 2 strokes, there's a couple of options for "universal" ignition modules to replace points on older chainsaws.

Great Work! How can i add a limiter (not a circuit braker, just a limiter) jumping one or two sparks to hold the rev constant at a defined level? THX for your Answer.
To do this, you’ll need a special module made for it. But just so you know, these types of CDIs are usually limited and won’t let the engine’s RPM go past a certain point.،5000-8000

greetings friends,To add a kill switch, connect the AC input wire on the CDI to the kill switch wire in the main wiring harness socket of the motorcycle. When the switch is turned off, the motorcycle will shut down.
In previous videos, I have fully explained how to install the CDI. The link is available in the description. Here is a brief explanation: This type of CDI requires an alternating current of approximately 50 to 110 volts to operate. It gets its timing from a pickup trigger located on the flywheel. Each time the pickup is triggered, the stator generates a spark, and the CDI is responsible for amplifying and timing the spark to ensure a strong and precise ignition at the spark plug.
I believe the 6 pin unit is a RECTIFIER/REGULATOR/IGNITION-CDI, capacitor discharge ignition, that triggers the coil. If that the case there is no regulation to the circuit and those diodes wont work as the rectifier for long before quitting. But there are simple cheap parts that can replace the diodes (full bridge rectifier) and a zener diode to regulate. 👍
I extract most of the parts from electronic boards or broken parts of cars and motorcycles or radios and televisions. But you can search on Google and you can find a store in your desired area
@@MrWolfDiy Thx for your reply! Would it be also that a mosfet needs a longer on time then a thyristor, because the thyristor wil stay open till the capacitor is discharged?
Hi, To make a CDI for this kind of bike, you’d need a pretty accurate microcontroller-based circuit that can handle up to 12,000 RPM, especially with the Ram Air system at high revs. It’s a tough job and will need a lot of trial and error.🙏♥️
Hi there, This CDI doesn’t have those features and is just a basic, cheap one. To get the functionality you’re talking about, you’d need to build a microcontroller-based CDI...🙏
Are you kidding? That's some of the shittiest solder work I've ever seen. Dry joints everywhere loose strands on wires and if you ever put this on a motorbike it will get shaken to bits. Oh the circuit schematic doesn't match the assembly, 4 wires built but only 2 connections in the diagram.
Me parece sorprendente que no dibujes correctamente los simbolos de los componentes electrónicos, soldaduras frias con cacahuates y todavía te atrévas a hacer un tutorial. El fondo musical de misterio...funcionara?
Yap, Perhaps you don't realize that this tutorial is the simplest way to build a CDI kit, intended for those interested in it, not for teaching soldering
Si sabes lo suficiente como para ver las cosas que está haciendo mal, sabés lo suficiente como para entender que de acá tenés que sacar solo los conceptos. No seas tan dramatico y dejá que la gente experimente y aprenda.
I don't think this is a cdi circuit. It looks like an electronic switch driven from the points. Yes there are some advantages, like increased efficiency and elimination of points 'bounce' but there is no high volage generation that I can see for charging a capacitor which then drives the primary of the ignition coil.
@1crazypj Well lots of equipment have capacitors - but I didn't realize the high voltage charge was derived from a magneto, otherwise there has to be a hv generation circuit.
@@ericwillis777 A magneto is direct generated high voltage, very common until about mid 1960's (and on aircraft where dual ignition systems are mandatory). Even though it's called flywheel magneto, it's really a dedicated charge coil supplying voltage to HT coil. Capacitor (Discharge Ignition - CDI) discharges into coil primary windings giving a very quick spike in secondary windings. It was used mainly on two stroke race bikes in 1970's as the fast rise time could fire spark plug when it wasn't ideal conditions (basically, points ignition had slower rise time so voltage could dissipate through carbon or excess gas/oil in cylinder)
Yes, but it is usable for engines with DC power. This point should also be considered: CDI has a faster ignition speed and performs better at higher RPMs.
You welcome,The end of the capacitor connected to the positive of the diode goes to the coil, the yellow wire. and use for AC input between two diodes connected to thyristor If you have any questions, I will be happy to help♥️
Hello, by the way, I am currently working on a five-pin (racing CDI) which will be released tomorrow or the day after tomorrow. You can subscribe to the channel and hit the bell to Notify you when the video is released.
This is a simple CDI and has a limited advance. To achieve a higher RPM, you need to make a more advanced version, which I will include in the new video to teach you how to make it.
It can be used for motorcycles with eight, six, and even four stator coils, but older motorcycles that have a contact breaker and do not have a pickup trigger, cannot.
@@MrWolfDiyhow is it working on AC with a transistor instead of a SCR? Like is it AC input, and pulsed DC out. But if so how's it working with a transistor? I've always seen AC input CDI's use a SCR for switching? Edit NVM I seen the schematic i see how interesting!
@@MrWolfDiy yea, I got confused when I herd transistor. then I seen your diagram which I didn't know you were going to show seeing that that's when I seen the BT151 was in fact a SCR Based on the circuit. I'll be trying out your DC verison, I've been wanting to build a coil driver, but I didn't want to just slap a 555 and all that together. Wanted to build a CDI module and then drive the CDI with a pwm chip of some kind. Thank you for sharing by the way this is something that I've kinda been looking for being honest, I've tried reverse engineering sone google schematics, but just seemed not do able based on what I've seen. I think your DC circuit will work on pwn, only issue I'll have is dwell time I believe not something easily controlled with basic ICs I think!
Hi Mr Wolf, I love your content, how simple you explain complicated things. BTW did you ever tried plasma ignition coil who has much more power, more then 40k volts? I would love to see if you make a video on extra power plasma coil or any plugin. Thanks and keep it up.
This CDI works on single cylinder motorcycles, in the case of your motorcycle (ATV)since it is two cylinders, I don't think it will work. You must use CDI with two separate(TCI) outputs.
Maybe next injection ecu? controlled by the throttle position sensor, the intake vacuum sensor (MAP), the coolant temperature sensor, the intake air temperature sensor and crankshaft position sensor?
Una versión para DC ? o se puede usar este mismo, veo que los diodos son para rectificar la AC de entrada, si le das directamente la corriente DC, funcionará igual? Gracias.
@MrWolfDiy You have shown demo in your video, a spark plug is used there, want to know the type of that spark plug, whether it has resistor or without resistor...or you can share part number of that spark plug...
Ypvs unit is mostly used in two-stroke motorcycles, I'm sorry, I can't make a ypvs right now, but to control the RPM, I can make a variable controller for CDI that can change the amount of timing. In the future, I will definitely share the video of making this.
The adjustable and racing version is available on my channel,And even this model.، which can also be used for two-stroke engines. What motorcycle do you have exactly?
@samuelhenrique5804 I will soon provide a tutorial specifically for two-stroke motorcycles, but the variable version already available on the channel is also suitable for you.♥️🙏
Stop complaining. If you can do it better, do it yourself. This vid was not made for the so called expert 0:00 but for the noob to try his/her luck. This is how people start in the magic of electronics.

To answer this question, you have to try it on your own motorcycle, performance may vary. But in general it can be suitable for single cylinder carbureted motorcycles with AC power, in fact this circuit is a cheap CDI, it may have some shortcomings. If you are looking for a better circuit, you can make the previous version that I made that does not have these problems, if you wish, you can watch it from the link below.th-cam.com/video/GsVEvlaLg24/w-d-xo.htmlsi=Lel_Xzo_64gaHdKQ
Nice big fat bluei! Love those workers hands, looks like they've been in a diesel engine? Dumb people ask --- Can it advance? No single trigger ign. system can advance. Unless it desides to send a spark before it's triggered.
You're kind, yes, I am also a mechanic. In the new video, I created a CDI with two triggers, which is also adjustable. The video will be released tomorrow. If you're interested, you can watch it... Thank you.
@@MrWolfDiy Yeh well I'm a mechanic from way back (almost 70 yrs young) my hands look just like that when I've been working on my little digger or truck. I hate electronics, my 2 old Datsun's have points ign.
A reasonable solution, but not terribly well implemented - Have a look on line for some idea's on how to actually solder and circuit board design using Perf Board.
I'm not saying I'm not a smart ass but I ask because I'm curious not because I'm a smart ass. What is the difference? I noticed the spark looked strong.
Greetings Ignition System: Uses a battery or the engine's dynamo to generate sparks. Direct current (DC) is amplified and sent to the ignition coil. CDI: Gets its energy from a capacitor, which is charged by a coil or generator. It discharges energy much faster than a traditional ignition system... and Ignition System, Found in older cars and engines with lower RPMs. But CDI, Used in motorcycles, racing engines, and machines requiring rapid ignition.🙏
Dear brother, hope you will repay to this,thanks. How to make an electronic unit to break the ignition coil negative but triggering from contact breaker points... This is for Honda CG125, 6v, magneto ignition model. No need a battery for starting. Appreciate your help in this regard. Thanks brother
I used to have a CG 125 motorcycle, it's great,and Currently I also have the transistor(CDI)model of this motorcycle. I don't understand exactly what you mean, in this type of motorcycle, the ignition system is a contact breaker, and the AC power generated from the primary coil is only connected to the secondary coil by an ignition capacitor.Explain a little more about your problem, maybe I can help, But my advice to you is to change the ignition system to CDI, I did the same thing on my motorcycle, it is very convenient, but it requires replacing the electrical equipment.🙏

I believe the 6 pin unit is a RECTIFIER/REGULATOR/IGNITION-CDI, capacitor discharge ignition, that triggers the coil. If that the case there is no regulation to the circuit and those diodes wont work as the rectifier for long before quitting. But there are simple cheap parts that can replace the diodes (full bridge rectifier) and a zener diode to regulate. 👍
no rectifier/regulator is only for charging battery 6 pin is standard for cdi boxes 2 different things
@gamehackertutorials No there is 6 and a 4 pin. The vehicle is hybrid wired, notice 6 wires.. he only connects 4 of them.
Nice Bro ❤
Diagram is incorrect. Has 4 wires but you only show 2. Missing black (ground?) and K white should be connected to 12v?
@@armunro blue : trigger
white: ground
Black: ac power
Yellow: ignition coil
What online store has the parts? and what is the board called?
I extract most of the parts from electronic boards or broken parts of cars and motorcycles or radios and televisions. But you can search on Google and you can find a store in your desired area
Very interesting.
The fire is very strong.
Thanks for watching, 🙏♥️
The same thing.
Can is ask why you use a thyrister instead of a mosfet?
Hi and welcome,
Thyristors are ideal for high-voltage CDI circuits due to their simple design and ability to handle high currents.🙏
@@MrWolfDiy Thx for your reply! Would it be also that a mosfet needs a longer on time then a thyristor, because the thyristor wil stay open till the capacitor is discharged?
Very nice! The soldering could be much improved so the circuit lasts longer😊
what about making one for a four cylinder bike like a kawasaki zzr1100?
Hi, To make a CDI for this kind of bike, you’d need a pretty accurate microcontroller-based circuit that can handle up to 12,000 RPM, especially with the Ram Air system at high revs. It’s a tough job and will need a lot of trial and error.🙏♥️
@@MrWolfDiy thank you for your reply
*REALLY GOOD WORK*
thank you very much 🙏
But what about ignition timing? the original unit shifts the ignition timing at high RPMs
Hi there,
This CDI doesn’t have those features and is just a basic, cheap one. To get the functionality you’re talking about, you’d need to build a microcontroller-based CDI...🙏
@@MrWolfDiy ok... but you can use it as a spare part for simple engines i guess... like lawnmower or something
@@MrWolfDiy or as a substitute for ignition contacts
nice soldering 😀
🤐🙏
Are you kidding?
That's some of the shittiest solder work I've ever seen. Dry joints everywhere loose strands on wires and if you ever put this on a motorbike it will get shaken to bits.
Oh the circuit schematic doesn't match the assembly, 4 wires built but only 2 connections in the diagram.
@stevelloydyep horrible looking i think he was being sarcastic i hope 😅5785
I like the music. Bumping
Me parece sorprendente que no dibujes correctamente los simbolos de los componentes electrónicos, soldaduras frias con cacahuates y todavía te atrévas a hacer un tutorial.
El fondo musical de misterio...funcionara?
Yap, Perhaps you don't realize that this tutorial is the simplest way to build a CDI kit, intended for those interested in it, not for teaching soldering
Si sabes lo suficiente como para ver las cosas que está haciendo mal, sabés lo suficiente como para entender que de acá tenés que sacar solo los conceptos. No seas tan dramatico y dejá que la gente experimente y aprenda.
I don't think this is a cdi circuit. It looks like an electronic switch driven from the points. Yes there are some advantages, like increased efficiency and elimination of points 'bounce' but there is no high volage generation that I can see for charging a capacitor which then drives the primary of the ignition coil.
I doubt he's running it on a points engine.
@martin-vv9lf yes, you are right, I didn't reakize that those bikes used a magneto, which will supply the high voltage to charge the capacitor.
It has a capacitor so it's CDI
@1crazypj Well lots of equipment have capacitors - but I didn't realize the high voltage charge was derived from a magneto, otherwise there has to be a hv generation circuit.
@@ericwillis777 A magneto is direct generated high voltage, very common until about mid 1960's (and on aircraft where dual ignition systems are mandatory). Even though it's called flywheel magneto, it's really a dedicated charge coil supplying voltage to HT coil. Capacitor (Discharge Ignition - CDI) discharges into coil primary windings giving a very quick spike in secondary windings. It was used mainly on two stroke race bikes in 1970's as the fast rise time could fire spark plug when it wasn't ideal conditions (basically, points ignition had slower rise time so voltage could dissipate through carbon or excess gas/oil in cylinder)
Can u make a video of making a DC powered cdi
Yes,I will definitely make it in future projects🙏
Can you show how to make cdi for 2 stroke engine?
I will try to make it in the future,What are you looking for, motorcycles or outboards?
Gostaria de ver para motocicletas 50cc 2t
Technically you can use a ignition module from a old GM HEI ignition. They cost like $20
Yes, but it is usable for engines with DC power. This point should also be considered: CDI has a faster ignition speed and performs better at higher RPMs.
Is there any circuit diagram just in case
The circuit is very simple and I have shown the diagram inside the video
@MrWolfDiy ok thanks may be skipped that part
i see the diagram but i cant found pulser/triger line, Where triger/pulser line come from brotha? Tx u
The end of the 560 ohm resistor is connected to the trigger, I used the blue wire in the video
@@MrWolfDiy so where line to the coil? Sorry i asking too much 😀
You welcome,The end of the capacitor connected to the positive of the diode goes to the coil, the yellow wire.
and use for AC input between two diodes connected to thyristor
If you have any questions, I will be happy to help♥️
@@MrWolfDiyim still dizy😊 but i will try n asking latter n this is great project brother, tx u👍✌️🙏

@MrWolfDiy ok bro I saw the diagram thanks 🙏
Can i use in 12 pin cdi
It is not possible, because it's DC, in the future, I will make and share the replacement of DC CDI 🤲.
Can this run 15,000rpm ?
This is a simple CDI and has a limited advance. To achieve a higher RPM, you need to make a more advanced version, which I will include in the new video to teach you how to make it.
@@MrWolfDiy Does this model advance at all ?
Nasty solder work there, mate.
Does it match with pulsar 150 UG4 model..?
Your motorcycle must be a CDI with two separate outputs for the ignition coil, (dtsi) and this CDI is designed for engines with a single spark plug.
@MrWolfDiy My pulsar 150 UG4(2011)has two spark plugs..can u make a circuit for Dual sparkplug pulsar CDI coil..
@@Nanduchandu3637it's gonna be easier to just buy a CDI man...

It can be used for motorcycles with eight, six, and even four stator coils, but older motorcycles that have a contact breaker and do not have a pickup trigger, cannot.
It can be used, but in my opinion, make the new version, which I will publish tomorrow, it is stronger and very simple, (CDI Racing)
Is it AC or DC cdi ??
It's AC CDI.
The DC version is also available on the channel.♥️
@@MrWolfDiyhow is it working on AC with a transistor instead of a SCR? Like is it AC input, and pulsed DC out. But if so how's it working with a transistor? I've always seen AC input CDI's use a SCR for switching?
Edit NVM I seen the schematic i see how interesting!
Hi, right ,TCI system is not AC, but
BT 151 is a thyristor (ScR) bro.
@@MrWolfDiy yea, I got confused when I herd transistor. then I seen your diagram which I didn't know you were going to show seeing that that's when I seen the BT151 was in fact a SCR Based on the circuit. I'll be trying out your DC verison, I've been wanting to build a coil driver, but I didn't want to just slap a 555 and all that together. Wanted to build a CDI module and then drive the CDI with a pwm chip of some kind. Thank you for sharing by the way this is something that I've kinda been looking for being honest, I've tried reverse engineering sone google schematics, but just seemed not do able based on what I've seen. I think your DC circuit will work on pwn, only issue I'll have is dwell time I believe not something easily controlled with basic ICs I think!
can you do dc cdi?
with this cdi.
I will put it in the next tutorials
For what CC we can use this ?
Most single cylinder motorcycles work with AC power, I tried it on 125cc and 250cc motorcycles, it worked.🙏
Hi Mr Wolf,
I love your content, how simple you explain complicated things.
BTW did you ever tried plasma ignition coil who has much more power, more then 40k volts?
I would love to see if you make a video on extra power plasma coil or any plugin.
Thanks and keep it up.
I appreciate it. Yes, I already made a lot, you will definitely see it in future projects.
What ably a cdi for a banshee twin cylinder carburetor
This CDI works on single cylinder motorcycles, in the case of your motorcycle (ATV)since it is two cylinders, I don't think it will work.
You must use CDI with two separate(TCI) outputs.
@@MrWolfDiyOkay can you make video of a cdi with two out puts

Great video and I appreciate you showing us!

Just check the circuit you drew as far as the cap is concerned.
Is this CDI for DC or AC?
AC.
Meron nman pala thank.
Maybe next injection ecu? controlled by the throttle position sensor, the intake vacuum sensor (MAP), the coolant temperature sensor, the intake air temperature sensor and crankshaft position sensor?
Hi,Dear friend, this type of CDI is only for carburetor motorcycles, sensors and ECU are not used،

Una versión para DC ? o se puede usar este mismo, veo que los diodos son para rectificar la AC de entrada, si le das directamente la corriente DC, funcionará igual?
Gracias.
No, the ac CDI requires a voltage of around 50-110V AC to operate. I will also make a DC version soon.🙏
@@MrWolfDiy thanks
Cool
In Demo, Spark plug is with resistor or without resistor

@MrWolfDiy You have shown demo in your video, a spark plug is used there, want to know the type of that spark plug, whether it has resistor or without resistor...or you can share part number of that spark plug...
It does not matter. The HT is from the coil. This is only the swiching part.
@@tinkerman9525 try practically then reply...
Ypvs unit make please...
Ypvs unit is mostly used in two-stroke motorcycles, I'm sorry, I can't make a ypvs right now, but to control the RPM, I can make a variable controller for CDI that can change the amount of timing. In the future, I will definitely share the video of making this.

Smh wish I knew about this like 2 years ago for my kt100. $180 just to replace it..
Yeah this won't run your engine at anything but a specific rpm range. It has no timing curve at all.

Would that be margarine or the bird?
Are there problems with false explosions or irregular ignition timing?
To answer this question, you have to try it on your own motorcycle, performance may vary. But in general it can be suitable for single cylinder carbureted motorcycles with AC power, in fact this circuit is a cheap CDI, it may have some shortcomings. If you are looking for a better circuit, you can make the previous version that I made that does not have these problems, if you wish, you can watch it from the link below.th-cam.com/video/GsVEvlaLg24/w-d-xo.htmlsi=Lel_Xzo_64gaHdKQ

Nice big fat bluei! Love those workers hands, looks like they've been in a diesel engine? Dumb people ask --- Can it advance? No single trigger ign. system can advance. Unless it desides to send a spark before it's triggered.
You're kind, yes, I am also a mechanic. In the new video, I created a CDI with two triggers, which is also adjustable. The video will be released tomorrow. If you're interested, you can watch it...
Thank you.
@@MrWolfDiy Yeh well I'm a mechanic from way back (almost 70 yrs young) my hands look just like that when I've been working on my little digger or truck. I hate electronics, my 2 old Datsun's have points ign.
A reasonable solution, but not terribly well implemented - Have a look on line for some idea's on how to actually solder and circuit board design using Perf Board.
Thank you for sharing your opinion.🙏
This is an igniter circuit, not a CDI
I'm not saying I'm not a smart ass but I ask because I'm curious not because I'm a smart ass. What is the difference? I noticed the spark looked strong.
with a slight difference,🙏
Greetings
Ignition System: Uses a battery or the engine's dynamo to generate sparks.
Direct current (DC) is amplified and sent to the ignition coil.
CDI: Gets its energy from a capacitor, which is charged by a coil or generator. It discharges energy much faster than a traditional ignition system...
and Ignition System, Found in older cars and engines with lower RPMs.
But CDI, Used in motorcycles, racing engines, and machines requiring rapid ignition.🙏

How to make an electronic unit to break the ignition coil negative but triggering from contact breaker points...
This is for Honda CG125, 6v, magneto ignition model.
No need a battery for starting. Appreciate your help in this regard.
Thanks brother
I used to have a CG 125 motorcycle, it's great,and Currently I also have the transistor(CDI)model of this motorcycle.
I don't understand exactly what you mean, in this type of motorcycle, the ignition system is a contact breaker, and the AC power generated from the primary coil is only connected to the secondary coil by an ignition capacitor.Explain a little more about your problem, maybe I can help,
But my advice to you is to change the ignition system to CDI, I did the same thing on my motorcycle, it is very convenient, but it requires replacing the electrical equipment.🙏
