Well, the vendor that I need to send my core back to does not accept "aftermarket" units. The somewhat holographic sticker on my dead alternator is faded heavily, so I can not tell who manufactured it. If anyone has somewhat detailed pictures of the alternator and that little hologram sticker, please post them. Thanks in advance.

 

Here is a pic of the stock alternator. I am not sure what 'little holographic sticker' you mention(?). The only decal on it says:

IC REG BUILT IN
N3A1 A3T0859
12V 100A 2403
Mitsubishi Electrical Corporation

 

Thanks guy!
