So on this ATV the batteries keep dying to the point it won't start I'm on my 2nd battery this week it took me until this one to figure out that my ATV isn't charging it's on 12.75 volts when sitting in the ATV and it doesn't go up when being revved what are the chances it could be the rectifier/regulator vs the stator or CDI. I just replaced CDI and stator from a used ATV through a shop and I would hate for one of those to be bad. I was reading a couple of posts about the CDI but was hoping it was the regulator is there a chance?

Alright so final update my ATV had a stuck piston ring and compression was low took it over to Power Toys Of Texas in Conroe and they fixed me up I appreciate all of y'all's help.

I didn't have a spark tester but spark appeared fine

Yeah I'm gonna do a compression test but if I was to hook a multimeter to the red 12 volt wire and ground the negative then 12 volts should come through it while turning it over correct?

I have a 2003 sportsman 500 ho I replaced the stator, pickup coil, ignition coil and I purchased two different CDI boxes it has fire and turns over but won't start any help would be appreciated as I am currently losing hair over this

Hi all, I have a 2003 sportsman 500 ho that I purchased a CDI for to replace the previous one however it was modified by someone else to use a different one I have all the correct wiring however I have to make the correct pigtail will anyone be willing to share a pic of how theirs is setup any help would be appreciated as I have been working on this bike for 2 months
