I've been trying to fix a wiring nightmare on a ATV 108,it's a cheap made Chinese kids quad,I can't seem to find out the make of it, however it is a 4 pin Cdi and rectifier setup, I started from scratch, I googled tons of diagrams I have lights it will turn over but is not firing, I have voltage to Cdi but nothing on the yb coil wire, I'm gonna try a new Cdi but thought I'd get some other ideas if anyone knows more than I have learned I'm still up in the air on what kind of quad it is the motor says 107^2 but sticker on plastic says atv 108?

 

Noodle's, if you haven't already done so, ask your question in the Chinese quad section for best results.
