nhcop,
I had the same issue a year ago with my 04 gz. Seeing you are having the same symptoms with your bike prompted me to register. Start on pg. 168 of the service manual (avail on this site) for some guidance. Your Rectifier is probably shot and your battery is not getting any juice from the stator. The stator puts out around 60 Volts AC and the recitifier (looks like a metal block with fins) located on the left side of the bike changes the 60 VAC to around 13.5 DC. If you start your bike up and unhook the two wire connector comming of the rectifier you should read at least 13.5 volts. If it says -13.5 volts no big deal, just swap your meter leads around. I was able to pick up a rectifier on e-bay for about $29 + Shipping. A dealer wants over $100.00. I hope this helps you out.

I did notice that the bolts holding on the rectifier were loose when I bought it. I tightened them up not thinking much of it. Makes me wonder??
