Different times.

That's what I thought. But the sheet that came with the regulator (which is made specifically for an ALTERNATOR) says that you may need to polarize it.

I have a charging system analyzer.

The tester will show:
Over charge (Regulator shorted)
Not Charging (Field Regulator Open)
Alternator (Rectifier/Stator)
Low Battery (Low Charge/Bad Cell)

The tester says that I have a regulator problem, not an alternator problem. The unit is supposed to sense the filtered and unfiltered output of the alternator so if the thing is working, the alternator is supposedly ok.
