I just got and installed a new battery for my '92 Talon TSi AWD manual (Interstate Group 86 at Costco, $100), and the car started fine. I tested the battery before turning the car on and it was at 12.45V, which is nominal I believe.
I then tested it after running the car for a couple of minutes, and it was now under 12V, which is of course not right. I assumed that something was up with the alternator for this to happen. So I turned the car on again, and saw that the alternator belt was in fact turning the alternator.
I turned the car off again, and pulled the cover of the high-power fuses, relays and fusible links on the passenger side of the engine bay just forward of the battery, and saw that the 80A alternator fusible link had in fact blown. My guess is that it was thermal shock after years of not being used and then finally having power put through it on a coldish late fall day. But, whatever, it needs replacement.
The OEM part # is MU840021, which is available at dealers or online for $10-$16. Thing is, I want to have the car inspected today so I can finally drive and park the damn thing on the street, so I need to find one today, if possible. Autozone has one for just over $4:

Would a generic aftermarket such as this one work, or as with so many other things, I should really go with OEM on this? If the latter, would using a generic one for a few days until I can get an OEM one be ok, or asking for trouble?
Btw, does this fusible link control any other electrical components? I noticed that my dome lights only turn on when the engine's running, and the radio turns on but there's no sound.
