Re: last resort before i take it into the shop
voltage measured at 5,000rpm should not exceed 14.8v when tested on the battery terminal leads. if you are showing higher then 14.8 when revving up to 5,000 rpm or even when idling then your regulator is not functioning as it's suppose to regulate the current. (ie. overcharging the battery will fry the battery)
try starting the bike up and let it idle.. see where your voltage is at for the battery when idling.. then rev the bike up and see where the voltage is at 5,000 rpm
if the number on the multimeter is over 14.8v then the rectifier you purchased went bad again. if the number is below 13.0 when the bike is at 5,000 rpm then the R/R has gone out. check to see again that the rectifier you purchased didn't burn out already.. since a rectifier is nothing but a diode.. they can go bad by excessive heat alone.
If you take it to the dealer they would to the same thing..
also your bike starts up fine after all the parts were installed then mysteriously started going bad again??
I would look into the part you bought. high possibility that it could have went bad.. just pure bad luck.. if you purchase a rick's stator and mosfet type rectifier from their site. they are really good about there warranty. I understand how this little problem can be a pain in the ass and on your wallet. overall keep your head up as you will soon fix the issue in the near future!
