Most parts stores have the ability to bench test alternators, whether or not this test can be done with your application, I don't know but it's worth a shot.

My guess is the regulator but I'm not familiar with the first gens and their parts.

As for the gauge. . . Move the yellow signal wire to the Trailing coil and see if there is no change to confirm that you don't have a defective coil. A failed Leading coil is one reason for a dead tach.
