Not sure I am buying the short idea. Usually when things short, fuses blow, and if its between the battery and the altenator it should be easy to find.
Let me ask you this. Is your Charge Indicator in the instrument panel showing a no charge indication? I guess it is a light on if not charging, and off if charging.
I good test is to check your battery voltage while not connected. Connect the battery with all lights off and the ignition switch off. Does the battery voltage go down? If yes, find out what is drawing current. Maybe a glove box light, or something. Another way to find out what is drawing down is pull fuses to eliminate circuits. Make sure you have a detailed map of which fuses go where before pulling more than one.
Ok, if the voltage stays the same, start the vehicle and see what the voltage is on the battery with the altenator running. I know before you said you changed both the altenator and the regulator, but why did you change the alt harness? Was something bad, corroded, or burnt?
My fist thought is like the mechanics of the altenator or regulator. You might want to trace back the ground for the regulator and see if it is sound. The diagram shows a radio noise capacitor at the ground. Maybe that had gone bad. Just trying to through some ideas your way.
Good luck and let us know what fixes it.
