Does the Alternator have a power supply back from the battery to excite the alternator? I had the same problem and despite trying several alternators found that a fuse had blown on the circuit bring power back from the battery. Or the bushes in the alternator could be worn out or the diode pack could be shot. Put a volt meter onto the small wire on the alternator and across to the vehicle body you should have battery voltage on this terminal.
