Are you suggesting that it tests good and doesn't work in the car? They may be testing it by, bypassing the internal regulator and it could charge that way as a test.
Regulator should be available separately if you are up to taking the alternator apart (doable if you pay attention) and isn't that expensive for this era - (famous last words) if what I searched was correct.....
Test shown was like this.....
****************
On some internal regulator AC generators, full-fielding can be done by inserting a screwdriver through a special hole on the back of the unit.
**************
If exactly like that and you have room you could test it on car yourself.
Are you replacing this all the time? That isn't right if so,
