The other side of the amp gauge wire is solid black and comes out of the radiator support crossover wire. It connects to the rad support terminal in front of the battery.

I missed this post. The wire that goes behind the battery for the alternator connects to the terminal post. It does not go to ground. So both wires for your amp gauge will be connected to a 12-volt source. Your amp gauge compare the voltage between these two wires to come up with a reading
