Day off today. Been doing some tinkering, and some studying of the wiring diagram. So right off the 80A main fuse, you get a red wire. This red wire goes to the ignition switch, with a branch going to the alternator. The alternator, which you may remember, I have disconnected (because it was blowing up my 80A fuses). I am also unsure of where I have that red wire routed beyond the alternator, but the diagram is showing it going to a two-pin connector along with a red/white wire. The red/white wire also originates from the alternator. I suspect somewhere in this information is the solution to my no-start. Wish me luck!
Update: Verified multiple things. First off, my alternator is 100% bad. I have continuity in both directions from the stud to the case, so the internal diodes are shot. If anyone could link me to the correct replacement, that'd be great! I've heard about poorly fitting alternator pulleys, and don't need more issues.
Second, the signal to the ignition switch is good on the engine side of the car. While beginning to explore the chassis side of the harness, I made a nice discovery...the fuse block under the driver's side has had some shennanigans going on. A lot of non-functioning things can be explained by missing fuses (IE power windows). I have improper fuses in some spots. Best of all, I have so far counted TWO connectors not plugged in. So this will be the area I explore next. Hopefully I don't need to strip this chassis down to nothing to figure this out. I know my ignition switch works enough to cycle the key on. I just don't get why it won't even try to start.
Second Update: More discoveries - The thus far dead cooling fan now works, with a fuse in. It runs constantly with the key on, engine off. That seems incorrect. Also, I suspect I have a bad ignition relay. That's ordered, and I'll pick it up after work tomorrow. I still never found the home for two connectors tucked up behind the interior fuse box. They probably plug into the back of it, I just don't have a mirror or good enough light with me to see. I did unbolt it, but it feels like there is a ton of connectors in the back. I can't blindly feel if anything is missing. Hopefully the relay fixes the car (I friggin doubt it at this point)
Final Update: I'm done working for the day guys. No new information, I just worked on pulling some interior trim bits out. It's fun seeing work Matt must have done ages ago (judging by the amount of corrosion on the non-OEM fuses), such as painting the center console trim parts black. The cool thing about this portable garage is that I basically have a paint booth. Just add fans. Once the car runs, I'm absolutely going to restore the body and interior. I'm even debating filming it and putting a series on YouTube - I've never done ANY body work, so I feel like it'd be useful to show people the learning curve. I just love the idea of picking up where someone left off, however long ago it may have been
