Also I would double check I just read where you took it to advance and had it checked out and they said it was good . I don't trust those idiots at the parts store to test anything , honestly I would check the alternator with a known good one . Another Idea is make sure your electrical wires connected to the alternator and into the harness isn't damaged or dirty . Another Idea too is check your fuse also which is under the dash I think it's number 15 right off my head .

and another note check to make sure your belt is on and super tight

do you have a light weight crank pulley??
are you using a jdm ecu???
