when I ran the GM alternator I ran the #2 (voltage sensing wire) as close to the battery as possible (battery side of the starter relay). There is [generally] a .6-.8 voltage drop (differential) between that and just looping the #2 terminal straight to the output terminal.
Don't sound like much BUT it makes a world of difference how the voltage regulator reacts at an idle.
