Blown stator?
I was out a few weeks ago riding down a trail and my engine just happened to die. When I tried to restart it, my battery was dead! It wouldn't start. That was the first time that had ever happened. Frustrated, I walked back home and came back a few hours later when the engine turned over JUST fast enough to get it started. When I got it back I charged it up with a charger. That was a few weeks ago. A few days ago, I was out riding in the evening with one of my little cousins with my lights on. After about 30 or so minutes of riding, I just happened to get out and noticed that my lights were super dim. Normally they're REALLY bright. I took it back to the garage immediately and killed the engine and when I tried to restart it... it was dead. I recharged it again but I don't think it'll last long. So, what do y'all think is wrong?

Well the battery isn't recharging when the engine is running. Where do I begin?

1. Measure battery voltage with engine off: 12VDC or more
2. Start engine and remeasure voltage: More than step 1, but less than 15VDC 3. Measure stator voltage while engine is running: More than 12VAC If #1 fails, charge the battery with an external charger and then let it sit overnight off the charger and measure again. If the voltage drops, the battery is bad. If #2 fails, first check your main fuse with a meter. Visually checking the fuse can sometimes fool you. If the fuse is fine, check #3. If #3 is OK and fuse is fine, the rectifier failed. If #3 fails, disconnect the stator from the rectifier while the engine is running. If the voltage is now good, the rectifier is bad. If the voltage is still bad, the stator failed.
