k im gonna bump this from the dead, cuz ive still got a few questions.
ive been driving on it since i posted this, and its been completely fine. the light only comes on for a SPLIT SECOND when i rev past 6k, then the lights dim. otherwise, its totally fine. ive read that sometimes it could be a loose belt, but the belt seems to be tight (there's only 1 belt, right?)
i dont wanna go spending 130 bucks and several hours on something that's not the problem...
