Scott,
The starter wire has nothing to do with the fan fuse. There was some arcing going on in the fuse holder that caused it to overheat and burn up. The fuse NOT blowing, tells me nothing is wrong with the fan, just had a bad fuse holder.

I suspect wires are shorted out at the tube going down to the starter, and that's what started blowing fuse links. I'm guessing the only wire that's shorted to ground and stuck is the purple solenoid engage wire. That was at least to start with. Others may be melted together now.

You've got to get those wires (tube area) checked out before we go much further. It's definitely possible now that there's some more wire damage behind the switch inside. That would be from the 10 guage experiment, but don't worry about it for now though.

Pics look like some of the wires on the back of the alternator may have crimp on terminal ends. That will all need to be done right and won't be a problem, or can be took care of, when you add a junction block. Convertible top piece might work, but something heavy duty would be better. I'll check into that.

Enough for now
I do have more thoughts on this and will probably have more questions.
I suspect the wire from battery to alternator may have a poor connection.
Test/check out those wires at the tube.
