i know there is a way how to but i am not for sure how to. wandering if there is any one that knows how thank you

 

a multi meter my Good man. . .first check for power going in and power coming out than test to make sure it has the right amount of power coming out. . .

a spark plug test light would be a quick easy test. . .if the light dont flicker you don't have fire than work your way backward to the CDI box.

The CDI box is a rather pricey unit $300-$400. . . a friend now a room mate of mine thought his went bad on his polaris 600. . . it turns out it was the stator and pick up coil even tho power went in and came out there wasn't enough coming out to keep it running. . .
so $650 later it runs like new or better. . .

thank you for getting back to me, i have done that i have it narrowed down to voltage regulator or the cdi someone had said you can test the cdi box with a meter in omhs just don't know the procedure if anyone knows how to let me know do not want to find out it is good the hard way thank you

 

Swap it out with a known good one. I've seen ohms checks in a couple machines manuals, but most manuals will say swap it for a known good or have no check at all.
