Which is inside the darn alternator. Figures. lol. Thanks for the info!
I will slide under there tomorrow to check the connections just in case, but it was new ground cables and such hooked up, the positive cable was reused. I'll keep my fingers crossed that something just came loose.
Thank you very much for the suggestions and info! (and hope I can find the receipt so I can get a refund if it's not just a loose/corroded connection...)

Okay, got my two test LED bulbs from SuperbrightLEDS today. I bought one each of the following:
1157-R45-T
1157-R24-WV "WIDE" Polarized
The R45-T is much like the ones I got for my PONTIAC emblem (WLED-RHP9 "Pure Red"), only with more LEDs and the proper base.
The WV is sorta like a flashlight LED, with all of the bulbs pointing in the same direction. Since the inside of the housing isn't reflective, I thought they might be better. I was wrong.
In the following pic - the top is my original 2057 bulbs.
The bottom - the two "inside" bulbs are still the 2057. The one on the outside left is the WV, the outside right is the R45. You can see that the difference in brightness between the 2057 and R45 is subtle (in the R45 favor), but HUGE between the WV and 2057 (in the 2057 favor). This applied even running around my street like an idiot checking at different angles.
Plus, as Ogre warns in his write up, they are not TOO bright, as to make it tough to judge the distance between the back of my car and any following vehicle. So I guess I'm ordering three more of the R45s!!

We did an alternator swap. While we had the old one out, we had it tested at Advance Auto....it tested good. We decided to continue with the swap anyway to get the higher amps of the CS. We put in a 140 amp CS Power Master alternator from Summit. We pulled the plug off a spare 88 harness I had, and wired it up. Fired it up, and we had 15 volts. Woo hoo. So, Vince pulled out to head home. He got to the stop sign, realized his blinkers weren't working, and saw that it had dropped to under 13 volts again. Same problem as before.
I am at a loss. Not so much that it isn't working (there could be a wiring issue anywhere else in the car), but more because it worked for a moment, then died again. I am pulling out the wiring diagrams....but would love to have some ideas on where to start.

So just thought I'd throw a quick post up.
The charging issue is still being investigated by Greg (CowsPatoot). To my understanding - he's chased and tested everything out the engine bay for the issue, and all that stuff looks good, so he thinks the issue might be in the engine wiring harness.
He has removed my existing harness and took one of his spares, and is in the process of building a new cleaned up harness for me! No more snipped and electric-taped off wires!
If this - for some strange reason doesn't fix the charging issue, at least it'll make it easier to chase things down.
He also knows a guy near him that can lengthen my A/C hoses! Greg is really going all out on getting things fixed up and tweaked. I can't express my appreciation enough.
I just really hope once this charging issue is fixed, it'll be the last (difficult) problem to creep up for a long, long time...

Finally heard back from the guy who has my F23!!
He got it all apart and inspected and said it looks great, if I wanted to be paranoid I could stand to replace the synchros. He's going to pull the gears off the main shaft so I can send the gears off to be shot peened and cryotreated, and just having the main shaft cryo treated. Then once I get those back, he'll put the whole thing back together for me and I can start making arrangements to have it installed!
CowsPatoot is making progress on the new harness, hoping that resolves the charging issue - or at least makes it easier to find.

And it's finally coming home tonight!
A/C should be working, Charging issue is fixed!
Mechanically, with the exception of a small/slow trans fluid leak around the seals, and having to retorque the valve covers... it's all working now!
The F23 is being reassembled, I wanted to hold off on putting it in until I got the LSD for it, but since the Muncie would need to come out to have the seals done (right?) I figured I'd just move ahead with the new transmission getting put in for now.
Got TLG's markers in the front, had to drop him a PM about an issue with the rear ones. Also got his courtesy lights and the trunk light. The stuff that hooked up right is very slick. Also got all the lights in the back of the car replaced with nifty LEDs, save the Amber (wrong base, my fault) and the backups (which I didn't see a point to doing).
Still quite a bit I want to do to it... but I'm just thrilled I can drive it! (with a top off on transmission fluid every 6 months or so for now. heh).

Pics! Pics! Pics!
BTW, the collector bolts like to back out. It is best to either double nut them or safety wire them.

Hey Guru!
Yeah, one of them there isn't enough room to double nut it. If I loose any more, I'll definitely find some bolts that have that safety-wire option. I think ARP actually made some specifically for that... I might have to hunt them down.
Pics! There are some pics in the linked thread. I don't have a decent camera. Just my lousy camera phone -- I lost my digital camera when we moved to Greensboro. I know Paul is going to have a lot of pics in his tutorial thread on the F23 swap, though!
As for vanity pics... my car is so filthy right now. lol. I haven't had a chance to get it washed, every weekend I've been pretty busy. Maybe this weekend! Maybe.

As excited as I am to just blurt out the numbers it put down, here's the events of the day.
Woke up at a horribly early time (for me), to be at Pro-Dyno by 9am (which is when he said for us to get there). Pro Dyno does tuning as well as has a full service performance shop. We get there about 5 minutes late, and there's a fox body Mustang on the dyno already, just built and in to be tuned.
So while Dan (the owner and head tuner, and all around a nice guy) worked on that, Brian went about putting on the bigger injectors and MAF on his T-bird that was getting retuned today (awesome news on that too).
The Mustang (which was up there for nearly two hours after we got there) had a calamity, due to a wastegate malfunction, so was trailered. By this time Brian had the new injectors and MAF in.
Dan told us he had another job that was going to be real quick, then he'd focus on ours. It was a brand new Mustang with very little done, mod wise. And it was on and off there very quickly.
Dan rolls Brians T-bird on there next, which had a mild peak increase, but a fantastic overall curve increase on the rest of the band, up around 30 HP/TQ in some places.
My turn. He gets in the Fiero and starts it up, and gives me this surprised look. "It sounds like an old Corvette! What the hell do you got in here?" "You'll see."
He gets it up on the Dyno and I open the trunk. He looks around, hops down, goes to the shop side, and calls all of them over to check it out. So that was pretty cool. They hung around for the first pull.
Wideband o2 goes in, wire reader (for the RPM) goes on, he starts it up, and looks at the screen funny -- because it's showing 18.5 on the AFR. He calls out to one of the other guys. "You got that sensor in right?" "Yeah!"
He gives it a little gas, and the AFR starts to get better, he gradually speeds it up, bringing it up to around 3k, and calls out to me. "What's your redline?" "6500!" he raises his brow and gives me the 'not-bad-nod', and starts sharply accelerating, my AFR gets rich... real rich, real fast.
Second pull, he only goes up to 4th gear.
Third pull, still only goes up to 4th, but gets on it harder. Shuts it down, gets out and says "We normally only put up the cars we tune on Facebook, but this thing is going on there!" he looks at one of his employees "Get this on there, call it Monster Fiero or something like that."
So the employee takes a few pictures and goes about doing that. Dan looks at me.
"Your primary jets are too lean, your secondaries are WAY too rich. I could feel it bogging down when they kicked in." and he shows me the AFR fuel line thingie, and explains more of it to me, and ends with "So get the jetting on the primary brought up a little, and on the secondary brought down a little." "How much more power will that get me? Like 3 or 4?" Dan shook his head. "Try 10 or 20." "Seriously?" "Seriously. Get it done."
So now that you know that my car impressed a guy who builds and tunes performance cars all day long, and knowing that there's more power to be had... the numbers! Dun Dun DUNNNN:
371 HP at a little over 6k, and 381 Torque at right on 4.75k.
Already called Scott and left him a voicemail to see about getting the jetting changed on the carb, and then going to go back.
Besides that awesome news, I"m even more excited about the fact that Scott told me once I get the fuel injection done, my curve will likely be much better, and I'll probably make better peak power. So I'm really glad I'm getting this carb dynos done so I have some before and afters.
The dynograph I have is printed on some glossy paper, but I don't think it'll cause any issues with scanning, going to try to get that done now and I'll get it up.
Edit: Here's the dyno sheet! I rotated it in Webshots, so the quality dropped some, but it's still readable. I can always turn on my PC with a real photo program and re-upload it if anyone thinks it's necessary.
My roommate had taken some video of the car on the Dyno, here are the two videos he shot. He was already hit up by a well-known Fiero Troll, one of the more active members over on RFT - I'm sure that's all I need to say for everyone here to know exactly who I'm talking about. lol Here's the video links.
