69 or earlier, so called "roundback" and single wire field. This type MUST use the 69 or older regulator. The don't generally charge as hard at lower RPM as most the "square backs"
 
My friend has his sisters '72 Charger at his shop and the alternator deal is killing him. Got two of the wrong alternators from the parts house he works for...not sure if the car ever had the correct alternator on it since his sister bought the car.

I've steered him this way to help him out... warm weather is here and she can't drive the car (georgeous '72 Charger with a mild 440/TF in brandywine paint. Very nice...)

I can't imagine where this alt. came from...yea I know Chrysler. I haven't owned a '60's Mopar since '68!

Send it to these guys... They are not far from me and make their own windings in house...

They saved us when my son had three bad 'parts store rebuilt' alternators fail the load test right off the shelf... Luckily we hadn't turned our core yet and took it to these guys and they got it right the first time... Made our old grungy alternator look and perform like new.... They even load tested it in front of us to show it was putting out...

Hey Shorty, I was going to buy an engine crane but I'll just have you come over and do the install for me. Ha Ha.

Can you post what is on it? Or what you think is wrong? Whether roundback or squareback it needs to be "isolated field" which some guys call "dual field." In other words field not grounded. Only other possibility I can think of is it's been modified (DIY/ aftermarket bracket) or it had the HUGE 100+ amp setup which should not be in that car, unless engine swapped etc

Any 70/ later alternator under 100A (original type) should fit and operate
 
Not sure of it's origin...
I seem to be missing something...

Title says "I'd this alternator" . The OP posted "not sure of it's origin..." But no photo or other info.

Then Krooser posted a photo of a round back alternator.

Then:
Chrysler round back alternator...

Used in the sixties with the single field alternator and solid state voltage regulator

Which makes no sense. Single field used a mechanical regulator dual field ( isolated field for 67dart273:poke::rolleyes:) used an electronic VR.

Finally (Post 7) the OP said:

So are we to assume the 72 charger has a 1 field wire round back alt, and a mechanical single field VR. AND that
Krooser is Shorty Medlock's friend who's sister owns the 72 charger?

is it april 1 again?

I will clear this up....

Im working with my smartphone which has the photos and I started the thread on my desktop. One was logged in as Krooser the other Shorty Medlock.

The two different screen names came about when I got hacked and couldnt log in as Krooser so I used an old name my friends called me 40 years ago.

And the photo of the alternator was on a different post...I found this old alternator under one of my mobile work benches. Thought I would ask the experts.
 
Ok so the alternator in the 2nd photo is one that was sitting around the shop, and NOT the alternator in the 72 charger.

Do you have a photo of the alternator from the 72?

Do you have photos of the parts store alternator
 
Yeh ^^ and that is what I asked. The old alternator you pictured WILL NOT WORK with a car using a 70/ later regulator. What we need to see is what came off the car, and what you tried to install that you say does not work. I don't have a crystal ball, Rusty is in charge of that ****

Identifying Chrysler Alternators (1960-1976)

If this is a beautiful restoration or original car then you may want an alternator that matches that look, as well as functions properly.
There's just a couple shops that can do that. And you can use a cheap substitute in the meantime.

One caveat. The ID thread only shows the standard alternators. If the car was equiped with Chrysler Heavy Duty or a Leece Neville alternator, it may have three wires connecting to the regulator. That would be one clue.
