1 needs to see power, or it usually won't start charge till high rpms are reached.
#2 is sense.
here's the issue.
don't ever hook a line to the sense/#2 that has a resistor or lamp in it. the sense needs to see charge voltage to set regulated voltage. if you put a line to #2 that has a lamp or resistor in line.. that lamp / resistor will drop voltage and tell the alt that the charge voltage is too low and make it charge it's gutz out.
