I have a 5 pin cdi on my Chinese quad. It's been replaced, ignition coil works. Tested it on another machine. Removed kill switch wire still no spark. Oh, spark plug too. Why in the hell doi not have spark?

 

*Trouble Shooter Guide for NO-SPARK Chinese Engines

 

Didn't help at all, I have tried 3 CDI's, a new Stator, a new spark plug, bypassing all the kill switches, and I still have no spark. I am at a total loss here.

 

Oh, I also have a new Ignition coil. This is just getting silly!

 

check ground from the stator

 

The stair ground checks out. I have come down to dueling or every inch of wire. Haven't found anything yet.

 

Stair=stator

 

all 5 china quads i have dealt with 70cc-110cc all needed re-tape or tubing as it seems they only use about a 1/2" long piece of tape to cover connections that are all side by side

 

I am in the middle of pulling out the old harness and re doing some of the connections. I found a loose one.

 

its a PITA but is a common problem i found on these and the gauge of wire seems soft to me all the safety switches seem to create havoc as well betting that loose one played a major role in the problem have a great day
