It was 104 in the shade last week and I drove the car in traffic to the office with the a/c on and the Pioneer 7" LCD head unit on and had no issues with heat or voltage.

I would start by seeing if I could get my hands on a stock alt or at a minimum having yours tested. If something changed after your short, that would be the logical place to look.

Alternatively, Id swap to the GM fan. Maybe it doesnt have the watt-consuming machismo impact of the Ford fan, but yall don't spend much time above 104 there so it'll probably keep temps managed.

I'm going to have mine tested. After testing the alternator with fan on and off the car sat till today. I go out today after work to drive it some to find a battery too low to engage the starter. Now I did have the car idling and the fan running some, but I wouldn't think that is enough to drain the battery this low. I'm waiting till after dinner and I'll go out and see what kind of voltage the battery has.

The last time my engine did this little burp with the engine wanting to stall out I came out a couple days later and the battery was dead. I charged it and checked for parasitic drain and found none. My DMM showed between 30-40mV. Which makes it sound more like I have an alternator problem.

Even with my FD alternator on my FC, I run a stock size pulley - both on the main and alternator sides.
It barely charges at night, at idle, with the headlights on...

I'm going to look into an overdrive pulley, but to be honest I don't even know where to start looking. I'll start by googling alternator pulleys and see what I can turn up.
