It's baaaack! HELP

I'm planning on checking the firewall connector. Unplugged and cleaned it a couple months ago when this issue began, but I didn't really check it thoroughly. The car IS running, but not charging.

Last step tomorrow will probably be taking the alt off and back to A-Zone to be checked. Probably only has 100 miles on it, so I have my doubts. Maybe the new ignition switch somehow fried it...
I really hope it's the ammeter. Gonna bypass it first thing tomorrow.

I'm leaning towards pushing it over a hill at this point
