    Why would an alternator start to smoke when you connect the batteries

    And yes I did connect them the right way round

      Am I right in guessing you changed the alternator..Is it a recon alternator...

      If the bridge rectifier was connected the wrong way round inside the alternator, or maybe just something is touching...

        It was a second hand alternator from a good source, so not sure if i have a problem with the wirring on the truck or just been unlucky with some thing going wrong with the alternator in the post

          isnt there a voltage regulator in the alternator, if thats kaput it could explain things.
          Say not always what you know, but always know what you say.

            Obviously a short of some kind and probably toast now. Mine smoked after washing engine down once. New alternator was needed.

              Check it's earthed properly
              If at first you don't succeed.........give up.
