Re: IML: 69 voltage regulator follow up

["Frederick Joslin" <fljoslin@xxxxxxxx>]

This posting has just taken on more significance to me. I just went out to look at the alternator on my 69.

I too have a 3-post alternator, but with a two pin voltage regulator. The wire connected to the output closest to the distributor on my alternator seems to have been replaced by a previous owner and goes only to the middle post of the voltage regulator. The other two outputs on the alternator go into the wiring harness.

Also, I have a green and red OEM wire connected to my alternator while the service manual calls for a green and black wire.  

If I was to "bet" I would guess that the wire closest to the distributor on the alternator (3 pole) which is connected only to the middle pin of the voltage regulator on my vehicle (2 pin) is not needed and is the output which has been eliminated on the two pole alternators. In this case, the two pole alternator would connect to the other two wires. The gark green wire from the alternator is called out from the wiring diagram to go directly to the right pin of the voltage regulator and no where else. You could do a connectivity test to verify this.

Also according to my manual the dark green lead at the alternator is the "Field Lead". Of course at this point I do not have much faith in the manual since it specifies a two pole alternator and a three pole voltage regulator and I have neither and one of the wires to my alterantor is a different color than specified.  

FYI The picture of the alternator shows the field terminal as a "spade" terminal bottom near the engine while the "output terminal" is a post with a nut on it away from the engine.

This whole thing is really wierd since my manual shows nothing related to a three pole alternator.

I would guess that you could get a two pole alternator and a two pin voltage regulator and just plug them in. Make sure the field and output connections at the new alternator were correct. The three pin volatge regulator wire should plug right into the two pin voltage regulator leaving the left lead dead.

If I was doing this, and I may have to, I would do some more trouble shooting first.

Good luck.

Thanks for the thoughts, I wish I knew a little more than just how to change out parts. Then I can solve my current (pardon the pun) dilemma of how to change out the OEM unobtainable '69 alternator with a later model alternator. Any one out there with any thoughts about this? Thanks.
