Back in about '71 or '72, some of the early 10SI-style alternators had a "dummy" regulator in place of the solid-state internal regulator, and still used the fender or radiator support-mounted mechanical voltage regulator.

I believe the terminals on those were oriented "I I", instead of the "- -" we are familiar with on the later internally-regulated units.

So, that explains the dual markings on some of the cases.

If the alternator will accept a connector with the terminals "flatwise", like the one in the photo below, I believe it will always be the correct, internally-regulated unit.

I will try to run down one of those oddball alternators, and post some photos just to clear this up. It may take me a few days!
