30, 41, 46, 50 amp alternators? Yeah RIGHT

Diodes do not change the output. You forgot to include the Neice-Vinelle (spelling wrong) on police cars at 100 amp. Some alternators seem to have different outputs depending on year. After all this time so many parts have been mixed and matched that part numbers are not a guarantee of its output. Only spinning it up will tell. I have the correct alternator on my car not for it's output but only for it's part number.
