So I have an 05 YFZ that I can't get to start right. It has a brand new fully charged battery and cranks just fine but will not fire until you hook it up to a car battery with jumper cables. I have had the starter checked and it is fine. I checked the stator and found that it is isn't charging, could this keep it from starting on its own ?? I would think with a fully charged battery it wouldn't matter if the stator was working or not but maybe I'm wrong, I hope I am because this would be an easy fix.
