OK so the seven wire three plug CD pictured above is for the jianshe 250. The 400 has a five wire cdi. Mike could you tell me what the numbers on your CDi are. It should start with JS or JT then some numbers.

 

It says qiyi js 400 06 2008

 

Thanks a lot

 

Ok Lynn I am back from work! I did that test with the red and blue and green and white! I saw on my meter .2 ac volts and nothing on the orange to ground! I used the ground on the battery, I dunno I that makes a difference or not

 

0.2 VAC is probably OK based on how other CDIs that I am familiar with work.

So you have power going to the CDI, you're getting a trigger signal (the 0.2 vac), and you not getting any voltage out. So that points to a bad CDI.

 

Ok! I am goin to look on eBay for a Cdi does it have to be exactly the same as the one I took off? I see some on there off of Chinese bikes that are 5 pin an look the same physically but not for my bike will these work?

 

I just purchased a new cdi same as yours. Try
chinesemoto parts or kazumausaonline or chinesemoto partswholesale.com they run anywhere from $68-99. Ebay I only found them for about $159-249.
Mine started right up

 

Don't waste your money on trying a different five pin. The shop I bought my motor from tried using three differnt five pins and fried all three trying to save money and not buy me a new one..

 

I bought one that is for it from chinesemotoparts that was only 68 but I had to spend a hundred in order to checkout but oh well I will hopefully have a good quad after for only 600 buck!

 

I don't know how long till it gets here but will let you all know if it works
