Hi there guys, my 1988 fourtrax has stop getting any spark. I am looking to replace the solenoid and spark plug wire. Could there be anything else that would need to be looked at?

 

Well I decided to buy a stage 2 CDI box. Hopefully this will also help.

 

Did you determine that thd CDI was bad? Or are you guessing?

 

Just shots in the dark and I figure a lil performance boost nvr hurt anyone "to bad". Of course in my situation its not that small of a performance boost.

 

Have you tested the coil? What size is the Fourtrax?

 

I am replacing the coil along with the CDI box. It is also a 300 bored .5mm larger.

 

Have you tried disconnecting the kill switch connector then checking for spark? I had a 125 Fourtrax that tested great on all of the kill switch test but wouldn't spark. I disconnected the kill switch connector and had a spark everytime. Just a thought

 

You know that actually worked!! thanks.

 

Cool! Your welcome
