CDI upgrade no spark
 

I have 2 crossfire 150 non r
GY6 motors
LH157QMJ motors
I bought Performance CDI,s
I bought them from ********** online
The dont seem to work ! NO spark !
Should be plug and play.
Stator is stock not sure how many poles never open it up.
My stock CDI is prong 3 nule so i know i dont have a dc CDI .
Any Idea,s on what i can do ? or were to look?

Hmmm..you sure the replacements were DC based?

Personally, I don't put all my money in CDI's. They are most beneficial with mods that require it.

the dc units look just like ac unit, on your cdi there is a 2 wire plug, if there are two wires going into that plug you have a ac fired system. also check to see if there is a signal ( very low voltage ) coming from the pick up coil wire, most are blue with a white stripe

My Gy6 is a AC system and the Perforance cdi,s i bought are AC , but no spark once plug in , so im not sure what the issue is . Hate to think i bought them and cant use them , is the stock staor enough ?

I have AC system on my GY6 , the cdi,s i bought are AC , no spark !
Is a stator upgrade needed? thought the stock one would push it!

the stock stator wil be fine. coming from the stator side of the case are some wires, look and see if one is blue with a white stripe, that one goes to the cdi. check to see if their is a low voltage signal coming from it
