Alternator question

How do you now if your alternator has an internal regulator or not? With my truck running with an external regualtor I have 12.5 volts at battery. When I apply my power probe with 12 volts to the blue wire at the regulator or alternator I have regulated voltage of 13-15 volts. When I shut off the truck and start the truck again it goes back to original voltage. Could I possible have a internal voltage regulated alternator installed on my truck with a external regulator installled? I have had the alternator tested and it is good. Replace the external regulator with new one. This thing has really got me confussed...............................any help would be appreciated......HAPPY NEW YEAR>>>>>>>>>>>>>>>>>>>>.
