I have not tested the stator... I don't really know how to, since I am a rookie with electrical systems. Also I don't own any meters or anything.
The headlight died one morning last September (the bike also stalled for no reason, which i thought was strange), and I lost both high and low beams. Tried replacing the bulb just in case... then I started reading on here and found that the issue was common. I read a post from someone about flicking the starter button to see if the headlight would come on so I tried that and it did come on, but it never seemed to want to come on when starting the bike. So I continued reading and found the blue wire trick. It wasn't until last night that I finally did it and it fixed the issue.
