charging at 3.50

[lawnmowerman]

so i just took off riding my 1998  vfr 800 FI ,kind  tearing it up a little.  on a nice safe road no traffic , turned off my motorcycle and went to start it again and the battery was almost dead would not start . I charged battery and went to see what it was charging at and it is charging a 3.50 volts and when reving it to 5000 rpms the charge voltage goes down from 3.50 to 3.25 and lower , is this strange that cant be enough to keep the battery charged can it? after battery charged the battery stayed at 12.8 volts , can anyone tell me an easy way to check the stator and or voltage regulator thanks lawnmower man

Google "the drill".  It's here on VFRD somewhere. It will walk you through a complete check of your charging system. You will need a cheap meter.
