[oldgoat]

I have 03 GREEN ARCTICAT 400 Automatic atv. I get no spark to the plug.I have changed the coil assm, cdi box and the stator. I have check the wires to see if I have a short ,I see none.Does anyone have any thougts on what it could be, is there a fuse that I don't see?

When you replaced the stator, did you check to make sure the magnets in the flywheel were all in the right spot? I've seen a handful of those have the magnets come loose and move around.

Yes I did look like they were where they should be. Now I have power to the front side of coil,but none coming out.I am thinking the new coil is bad any thoughts on that.thanks

Can anyone tell me what tells this motor when to fire the plug?
