Alright this is more of a check for me then anything else, but let me give you the background...
So to start things off as many of you know I powder coated my valve covers, UIM, throttle body, and throttle cable bracket. I removed all of these components from the engine which also involved disconnecting a lot of the upper engine electrical connections and pulling the harness back to gain access to remove the rear valve cover. I only disconnected what I needed to (fuel injectors, TPS, IAC, coil pack, coil pack ground strap, IMRC box) where I then pulled that section of the harness back over the passenger side engine mount. I then reassembled everything and fired up the car. Everything ran smooth.
Two days later (today). I started it up and noticed the battery light was on and that my volt gauge was reading 11.5V. So I charged the battery for a few hours (it was around 12.5V) started the car, same thing. I then pulled out my spare battery, which at the time I installed it was reading 12.63V. Again same story battery light on and volt gauge reading ~11.8V
So I checked all my grounds, cleaned the battery connections in the trunk and in the engine bay. Restarted the car, again no change. I did the quick check to see if the fog lights were working and they definitely did. I then pulled out the coil pack and checked continuity from the mega fuse to my positive distribution block, good. Checked across the mega fuse, good. Then I pulled out the creeper and rolled under the car, disconnecting the alternator connections pulled the harness up top and checked continuity from the alternator post connection to the mega fuse, good. Since I had everything disconnected I went ahead and performed the alternator wiring fix and then reconnected everything back to the alternator. Restarted the car (battery had been charging the entire time I did all this) and same thing battery light and volt gauge reading around 12.2V
So with all this I'm guessing the alternator is toast. I just don't understand how it just all of a sudden crapped out. I have a spare alternator from when I replaced my 2.5L back when I bought the car figure I'll take it in and make sure it's in working order and swap out the alternator tomorrow.
However just want to check, with all that said is there anything I missed.
