HI,
My son's Yamoto 150 is getting no spark.
I replaced the CDI and still no power to the coil at all.
I looked at the ignition switch and the terminals look fine.
Could it be the stator?
Should there be voltage to any of the coil wires when cranking the engine?
It cranks over fine and did not get washed or rained on.
Thanks!!

 

Did you check the spark plug?

 

There is no power going to the spark plug or even going to the coil.
Thanks1

 

I had the same problem on my 150 and I had to replace the stator. This fixed the spark issue.

 

do a search on google how to test coil on atv and you will find something it wont let me post the place. also make sure your plug is good put it in something else and make sure you have spark out of plug first.
how many hours are on machine

your are going to need a multi meter to test it its an ohm test can't remember everything
in my younger days yeah not now I have crs
