Looks like another bad alternator.
Battery voltage on one terminal, ground on other full fields the alternator. So any question of regulator or wiring is eliminated.
So, find a good used squareback and try it. The new stuff is aparrently junk. Could be a bad diode again, or a sticking brush or broken winding in the stator or rotor.
Ya I have a feeling its the alternator again. I'm either really unlucky or somehow my car keep shorting them. I'm just afraid to get another one and it stop working as well seeing how 3 stopped working this year each after very little use
