Delco alternator decoding

[bbdon]

I have looked in my copy of CBTN 65-69 for you. 9f23 seems to mean June 23rd 1969
The 63a tells us that it is rated at 63 amps.
Alans book does not list this number, and it shows no application for a 63 amp alternator on a Chevrolet passenger car for 69. It may be a shortcoming of Alan's book, but possibly it means that the alternator is for a truck or for a different GM division. I also looked in the 69 Shop manual, and the number is not listed in there either.

Thanks for checking. Could it possibly be a B-O-P type alternator? If yes, where would be a good source to look?

It does work fine, though - I had it tested.

My interchange book shows 1100774 as a 1967-70 Buick alternator. It says its a 55amp though?

El Camino,
Thanks! You are the first person to actually say that they have found that number. I've been looking at the stamping, and can't seem to decide if that last digit is a "4" or a "1".

Does your book show a 1100771? If yes, what is it. Thanks a bunch!


Martin,
Thanks for the information. Did you get your dash lens replaced?
