Hi la1,
It is a NEW and CURRENT problem for me. Some time back my previous alternator failed. When I took it apart, I saw that one of the diodes was dud. It looked like the entire rectifier assembly had been overheating, but I put that down to the shorted diode. My car is a 1979 V12 Jaguar. I replaced the faulty rectifier, and changed the voltage regulator. But the symptom that I described had not gone away. I dismantled the alternator again, and concluded that there may be shorted turns in one of the stator windings. I could not source a replacement stator coil, (NLA), so I had to fit a replacement alternator (later design, as original pattern alternator was obsolete)
