Delco 10SI alternators normally has three connections on it. A large wire for the output to the battery, a two wire connector stamped on the alternator with #1 and #2. 2 should have 12 volts all the time, 1 should have voltage when the key is on only. 2 is the external sense to the regulator for sampling the system voltage.

If the shop checking the alternator used an external source on the #2 connection a broken internal connection inside the alternator would be missed.
