Stator and pulsar coil are within specs, no issue there. Do you have the 5 pin or 6 pin china CDI? If itís a 6 pin, it could be a DC cdi by mistake.
OEM CDIs are the best, but the Chinese CDIs do work on many different engines as the input range is wide.
If you detail how you have it wired, I can tell you what the problem likely is. Also, do you have a spare, known good, ignition coil you can try?
china c.d.i's are pure junk !!!. I could be wrong here ?, but you sure seem to push china parts a lot sense you joined the forums here. please don't tell our members china parts are good ?, they suck balls bro !. they can fry your electrical system in a heart beat !. if you want to put china junk on your machines , then please..by all means..have at it !. but don't try to push that crappy junk on members here. china parts are not worth messing with. THIS IS A 100% PROVEN FACT COMING FROM SOMEONE THAT HAS BEEN DOING THIS FOR OVER 25 YEARS !!!! :-).
Are Chinese parts less quality than that of oemís, sure. Does that mean theyíre totally and absolutely junk and do not work? No.
80ís-90ís model ATVs are electrically rather basic in design so there arenít any parts that can be fried, except that of the CDI. Many will spout theyíre junk because they donít know what theyíre working with. Most common cdiís are 4/5 pin square single connector or 6 pin with 2 connectors. These both come in AC or DC input. China simplified this in a bad way as they made connections the same, regardless of CDI source input.
Case in point, Ď88 and maybe Ď89 trx300 CDI will plug into the later models, but it wonít start. Why? Is that CDI junk? No. It has the same connection, but the input signals are not the same pins on the CDI. Similar concept as where one canít run a DC cdi on an AC bike or vice versa. (atc185/trx300).
The guy trying to get his engine running lives in a country where buying an OE part is out of the equation and it doesnít even seem as the engine is running an actual wiring harness. Therefore, he can use any CDI he wants to get his experiment running.
Iím not pushing any agenda or any specific parts from any one manufacture. Iím stating that other non-oem methods plenty capable of working, especially if there are younger guys with less capital that want to fix up an old atc or trx they got for free or $50. This person may not be able to swing $150 for a cdi and $150 for a carb. Before you know it, the amount of money spent on parts is higher than the cost of a running machine.
It could be a cheap, fun hobby for some guys/ gals. Grab a wiring diagram and some parts and Iíll teach you how, if you like.
Want to know how I was able to wire a Yamaha to run a Honda CDI?
