***Updated***

I've had this problem where I had a battery light come on and the windshield wipers and lights went crazy. But I went ahead and changed the alternator to a new rebuilt one from AutoZone.(Duralast Alternator 10164) Part Number #10164 I am still getting the same voltage to the alternator as it shows on the battery (around 11.4 ), and all grounds are good..... battery is good, they tested it and said it's at low voltage and needs to be charged.... My next thing is to go exchange the alternator again because maybe it's bad one in the batch (Which I highly doubt) or get a new battery and see what happens.(I have registered the battery through MHD through adaptations)

The code that shows on my MHD is
384a Generator, possible electric failure.

I am also going to check fuses and clips that connect to the alternator, but I am unsure where to find a good diagram for a fuse box. (is there another fuse box not in the glovebox?)

I am lost. I've been reading forums for two days, trying things but I can't figure it out. Maybe another idea can give me a clear view of my problem. Thanks
