Has anyone tried this with any success? I bought it new for $5 and hope to get more than my money's worth...obviously it will take some modding...

Cheap CDI
- Thread starter skrew37

I didn't receive it yet, (online auction) but it looks to have 4 poles and says it will work with 150-250cc dirtbikes and atvs and 50cc mopeds. I bought a cr80 ignition coil that I want to wire it up with. I guess I could solder some jumpers to it and attach it to the ignition coil and see what happens. If nothing, then I guess I'm out $5 but on the plus side, gained some experience.
ok. i think the 2 isolated poles are the "red and black" wires that go to the ignition coil. after that, i don't have a clue...help?!? I definately need a wiring diagram for this...

If you can succesfully mod these to make it work for a motorized bicycle i would be happy to buy one from you. I dont like the CDI that these come with.
keep us posted
keep us posted
If i can figure out which poles are which, I can def get it to at least "work." Work "better"? I don't know...
But you'd need an actual coil for it too.
Look for CR Super Coil, looks like it's right up your alley, as it's coil and CDI box combo.

Ok here goes... I created a parts drawing/wiring diagram and from what I've researched, I THINK this is how you would wire it. Still waiting on the parts, so I can't test it. PLEASE, please, please anyone who knows wiring look at this, revise it, and let me know what needs to be changed. I'm a 3D mechanical designer, not an electronics pro. I appreciate any and all help guys. Thanks!...

It could very well be. I found another one of these cdi's on ebay where the seller labeled all of the pins. That's where I got the information. I'm just wondering were the black and blue wires from the engine go. And for that matter, I didn't even take into consideration the white wire that most of us tape up. Maybe there is a place for that on this cdi. Attach it to one of the grounds maybe? Let's figure this out and maybe we all can have great ignition systems for under $25. Hop on board. Teamwork!
I'm upset at myself cause I was looking at these the other week and found a diagram on some random forum.
Here's the pic from the other auction. And his numbering labels as follows:
1 KILL SWITCH, 6 STATOR, 5 GROUND, 4 GROUND, 3 COIL, 2 GENERATOR PULSE
(I really only half know what this means)
We have 3 wires coming off the engine (black, blue, and white) there are 6 pins on the CDI and 2 terminals on the ignition coil.... maybe one of the pins is unused?

It looks ok to me too. I should be receiving my ignition coil today or tomorrow, but who knows when the CDI will reach me from Hong Kong. Maybe this weekend. I'll make sure to take lots of pics of this wiring process. Watch, when I finally get this working, it will probably work just like the stock CDI...
well these are low compression motors so it wont be a performance mod just more reliable setup because the ignition system we have is S***
