alternator broadcast codes

[jvanduerm]

Does anyone know what broadcast code would have been stamped on the alternator of a 350/300 L48 car (69 SS) with air conditioning? The alternator part number is 1100843. I have been told CD was used on cars equiped with AC but wonder if there was any diference on the L48 small block? Thanks in advance for your help.

The engine doesn't matter. All 843 alts would have the same broadcast code. And it's not CD, but NF.

Jeff,
Don't know why the difference, but I have lots of broadcast sheets and every 69 AC car is a NF.

Here's a pic of an 843 alternator from my 71 Chevelle.

I don't have all my references here in CR, but 693 is NL (not CB).

This may be a new can of worms - would the code be different for the same alternator part number when used at Norwood for Camaros, then it was when used at St. Louis for Corvettes.  Cause then there may be lots of changes needed?

Typically my lists are based on Corvette research....
which is farther along then most other Chevrolet car models.

How about the 61 amp 1100750, is CD correct?

If anyone has an '825' CT laying around..  I'd buy it..

Shouldn't be. The Anderson (Delco) plant would build the part, stamp the part # and broadcast # on it and ship it to whatever plant needed the order.

Nope. When some aspect of the alternator changed, its part number changed (like just re-clocking one case half relative to the other), and that also changed the broadcast code.

That was part of my old job - pulling alternator broadcast codes for new part #'s. If it was a revision, the code would stay the same.
We had a book that we recorded the codes in - the code could be any two digits. (But they progressed in a logical way so we could keep sane.) The code would get picked up in the BOM and would be used in the plants for the broadcast sheets.

Reviving this post. I don’t see a broadcast code for my alternator. 1100817. Any idea?
