dont blame the alt just yet..my mom has an 02 GV v6
it started really slowly and would idle fine..but the min u put it in drive it would die ÂÂ

i got all worried and thought it was something major...all it was was the batt needed to be charged and later replaced lol
edit..i also forogot to mention that my batt died one night presumably from the stereo

lol
but we got a jump start..and the car drove..it just had no battery power lol if u turned on the heater the lights would dim REALLY badly because it was running straight from the alt
