Just to cover all the bases....
1. Are you sure you have your volt meter set to AC volts. (not DC volts)?
2. Are you measuring with the black lead from the alternator disconnected and one meter lead on it, the other meter lead to a good connection on the engine block (ground)?
3. I agree, the magnets do not lose their power, but I have seen them come loose and move out of place (they are epoxy glued) and give bad readings. But 9 times out of 10 they disintegrate and cause havoc.
If you can verify all of the above and still see only 14VAC, I don't see how it can be anything but a bad alternator....
BUT - You say you bought the new a alternator in May from Amazon. Did it ever actually fix your problem and later go bad, or did it never help at all? That would give some clues.
And - Do you still have the old alternator? If so, put it back in and run same tests and see what you get.
Best I can do, Good Luck.
