    SOHC and DOHC alternator interchangeable?

    Hey guys,

    Wondering if you knew if a SOHC and DOHC alternator is interchangeable? Any differences between the two?

    Thanks!

      Good to hear.

      Had a Miata alternator on there and the bearing was noisy at 4000RPM and only output 13.2V no matter what RPM.

      Replaced it with a used DOHC alternator and I am seeing 13.6V no matter what RPM and the belt squeals all the time although it's on there tight ... again bearing going bad.

      Now looking for yet another alternator and not sure if I should spring for a new one of try another JY special.

                did you have it custom rewound?
                Isn't the MPV alternator a direct swap just need to change the pulley. you get like 80 amps instead of 65 or something like that.

                  I had one rebuilt to 100 amps once. That was good.

                    What I do to see if parts are the same, is I go to a site that sell auto parts and see if the part numbers mach up.

                      A belt fixed the issue - good thing I investigated further before buying an alternator.

                      Also MS reads low on the voltage side, 13.5 at the MS is actually 14.5 at the battery. All's good.
