QUOTE(oldschool @ Dec 30 2014, 06:28 PM)  So I do I test this thing 2 ways to test it. Put it in the car; start the engine and see if it regulates the battery voltage to about 13.5 to 14V. Must measure at the battery. This assumes the alternator and all wiring are ok. Test it on the bench. A bit more involved. Put a DC voltage across D+ to D-. Put a load resistor of some value equal to the resistance of the alternator armature; maybe 100 ohms between DF and D-. Vary the dc voltage from 12 to 15V while monitoring DF to D-. Below 13.5V (D+ to D-) the voltage from DF to D- should be near the DC input voltage. Above 14V (D+ to D-), DF should be zero volts. I've never tested one like this but this method should work.
