1972 SJ alternator
 

Did the 72 come with an alternator that was internally regulated. I don’t see a voltage regulator under the hood . Thanks

Yes.

Being an SJ, if it came with rear defogger and AC, it would have an 80 amp alternator

Correct, #1101015 for the 80 amp.
(1100928 for 55 amp)

Alternator
 

Thanks for the reply’s. I was under the impression that GM didn’t start internally regulated alternators until 73-74. Thanks for the info and my car has A/C no rear defrost. And power windows.

I was thinking it was 1971 when all were internally regulated?
I'm a Firebird guy and know the 1970 and newer were internally regulated.

But i'd have to look at the distributors again for the years.

:confused:

Looked in SM and it looks like 1971 they are internally regulated?

I learn something new an all the time. Thanks for for all the help.
