1966 dart problems, help

just checked my alternator. I have one green wire going to terminal on outer edge of alternator, one blue wire going to terminal closest to water pump and the black just as yours. If it's the same there should be another terminal just like the one for the blue wire just across from it. Check to see if maybe it wasn't broken off inside the wire terminal.
