It might have gotten jostled around during shipping?

I unplugged and reconnected everything from the battery to the alternator to the voltage regulator and that didn't seem to fix the issue. I decided to pull the alternator to get it checked out and I've got the battery on a trickle charger. I'm going to tear into the instrument cluster later today and triple check the coil and distributor connections.
The car won't be going anywhere for a while as I've got the steering column pulled apart to replace the upper bushing, which had crumbled to pieces causing play.
Update: I took the alternator to Advance Auto Parts (don't judge) and their machine failed it. It looks like one or more diodes in the rectifier are bad so I'll be ordering a replacement from RockAuto. I still don't know if the regulator is also bad but this is a start.
