73 Dart Alternator doesn't show charge anymore.

I've removed the grille lamp bulbs for now as I have indicators on my headlights, I'm pretty sure they make new sockets for these lamps, since it's just a piece you can disconnect at the connector downstream. So I'll probably end up replacing the socket and getting an LED replacement bulb to match the rest of my lights, assuming I can find an amber one.

But yes, currently the brake lights do not work, and that red wire is the only other thing that's different about the circuit, so I'll try to connect it with the 5A tomorrow and check if it's shorted at all, before I plug the splice into the non powered side of the 20A and test the brake lights.
