Bad voltage rectifier?

[minieggroll]

So when I took the bike for a check up, they informed me that I had a bad voltage rectifier and it was over charging the battery.

I planned on taking it in/fixing it myself but yesterday after riding, the new battery I bought last week's cover popped open and started releasing sulfur gas (smelled like rotten eggs) and was super hot after riding for about 30 min. Now, it will not even start my bike without a jump or push start.

In addition, my headlight burned out 3 days ago most likely due to the voltage issue.

Anyone know how to replace a voltage rectifier or have any advice?

Thanks!
