Gz250 battery not charging and stator and rectifier tested please help

[jambo6984]

i desperatly need help my battery on my 1999 Suzuki gz250 isnt charging up anymore and i have no clue what it could be, i have checked the stator and rectifier regulator, the test on the stator showed not grounded and pin to pin showed 00.9 on all three pins and the rectifier showed 0 0 0 , 395,413,406, 0 0 0, 415,389,415, so everything serms to check out i also checked the stator while running it showed 50 to 60 while om choke at about 2,000 rpm, also checked fuses, and the battery is only 2 months old it worked great for awhile then all of a sudden started not charging, not sure about the previous battery when i bought the bike it was dead and looked old, im not sure what else to check, any help would be greatly appreciated
