testing voltage regulator
Here is a simplified diagram from MyMopar
As you can see, the green wire only goes one place..........from one alternator field up to the regulator
The blue is switched 12V from the key, and feeds the remaining field, and the regulator
The green basically controls "the amount of ground" on the field. When you clip the green alternator to ground you are causing full battery field current, some call this "full fielding" This should cause full output on a good alternator.
