Alternator Question?

I think what is happening here is, this is a dual field (squareback), and if you have the old style voltage regulator, then you must attach a small wire from the field terminal (the one nearest the ground screw) and attach it to the little ground screw thus grounding the field terminal to the case of the alt.
However if you are using the newer voltage regulators (triangle plug type) then you do not do any of what I just mentioned. What year is your Dart? Which alternator is this that you purchased?
