Charging System Troubleshooting--Blown Ignition Light Fuse?

[ACHiPo]

The third fuse down on the right (facing forward) bank. It is the fuse for the “I” from the voltage regulator.

I bought another alternator today as they weren’t able to test my old one and they’re closed tomorrow, but I really think I have a pretty big short someplace, not an alt problem. The battery checked ok, but that’s just because it was fully charged (not a real test of the battery cells—I still suspect it given the reported issues with cell shorting on gel batteries).

OK, when I pull the wiring diagram up for your numbered car, I do not see the "I" terminal wire of the VR running to the fuse box. It runs straight to the red ignition light. The "A" terminal of the VR runs to fuse #4, which also runs your flasher.
