Need Help Identifying GM Alternator

    I have what is believed to be a 3 wire GM alternator with the internal regulator. I bought it at a swap so now I need to confirm. It has the typical one large lead on the back of the alternator for the power and then a Field 1 and 2 next to each other on the perimeter of the housing. I tried to take some numbers off of it, so here's my best shot at it. The numbers are in two rows, the top row is 1 102913 61 ? and the bottom row is SK 1--12v NED.

    I'd like to confirm that its a 3 wire and the amount of amps it will generate.

    Thank you for your assistance.

    are the terminal pins in a straight line, or parallel to each other?

    straight: -- --

    parallel: | |

    if it's straight it's internal, if they're paralle it's external regulator

    This guy put some serious time into putting this article together an it is simple to follow.
    Be aware that he is converting a Land Rover to a Delco alternator but it is a great source of Delco alternator info as far as the alternators we would most likely be interested in running.

    Thanks everyone. That was very helpful. Looks like I have a 3 wire with internal regulator.
