Wild SWAG -- your R/R is fried, (hint from the brighter headlight when reved) and it lets the stator charge the liven shit outta you battery, and now your battery is fried too. Guesstimate solution, you need to buy a new R/R and plan on a battery too. On the R/R, I would make sure it is a MOSFET style design or if you are decent with wiring, grab a compufire series design. (fix it soon, otherwise it will fry other stuff too. ) Here's good chart for figuring it out if you can use a voltmeter. http://www.electrosport.com/media/pdf/fault-finding-diagram.pdf Btw -avoid electrosport parts, not all that reliable.
