HI, I recently purchased a 250cc atv,
I put a new Battery in the quad, and found out I was getting no spark, also i found a plug it has green and yellow wires in the loom, It looks like it clips on somewhere maybe a ground? I'm not sure

I have attached pictures, please help me identify this wire, and possibly the make of this 4-wheeler, and any other possible things to check for no spark, thanks

 

it appears to me to look like a 2004-2006 250cc NS-250. don't know much about them....

 

Can you find the CDI module and post pic's of it?

Got a voltmeter?

I don't know what the plug is, but we can start with the no spark problem.

 

that almost looks like a plug for the charger i just went threw a no spark issue turned out it was the kill switch where ther start button was never know
