Datsun 1000 uses the early Datsun alternator, A Mitsubishi or Hitachi unit with a four-spade rectangular connector. It was available in 25A or 30A versions. This is the same alternator as used by Datsun 411 and early Datsun 510. It is the same diameter as the more modern Datsun 1200 and 510 35A alternator.
