I need to figure out where the wires connect out of the wiring loom.
You're confusing being grounded with not having voltage. That is the only explanation for not having a blown fuse and the alternator going in and out when you wiggle the wires. That small wire is breaking connection not going to ground. Think about it, no manufacturer in their right mind would run a supply wire without having a fuse on it.

Put a meter on the wire going to the "L" terminal and watch it go from 12 to 0 and back.

Now trace where the wire is loosing connection. Chances are it's broke inside the insulation and you will be in for a deal trying to find it unless you have a "sniffer".
