AAW Alternator?

I have a 1967 V8 with the alternator on the left side. I just ordered the American Autowire kit 500661. I understand that I need to upgrade to an alternator with an internal voltage regulator. Does anyone know of a part number, or an application that would fit to replace my alternator?

Try here. Below the explanations is a list of certain alternators you can get to match the needed clock position. I used it to get a 12si 94 amp 9 o clock alternator for my 68.

Re: AAW Alternator?

You have to decide if you are more interested in power for stereo fans and water pump, or orginality. A SI alternator has to spin to 3,800 RPM to achieve max rated power. It will leave you with dim head lights at idle. A CS out put's it's higher rated amperage at 2,200 RPM. Because it has a higher amp rating it has a reverse flow cooling fan that doesn't look like a DN (the external regulator) or a SI (the first transistorized internal regulator alternator). How important is that difference in appearance? Just think that a CS is capable of out putting more power at idle than most SI alternators are rated for. Like all alternators the regulator determines the power out put based upon demand.

If you can live with the difference in appearance you can simply by pass two wires at the external regulator and attach a LARGER (to handle the higher rated power) single wire to the back of the CS and you are good to go. It will not self excite the windings until it exceeds 2,200 RPM; but once it has done so it runs self regulated until you switch off the car. If you can not live without the alternator being activated at the hit of the throttle AAW sells a pig tail that you splice into your existing wiring to activate the alternator at the hit of the key.

By the way you can easily clock any SI alternator by putting a wooden tooth pick in the hole in the back to lift the brushes off the commutator of the rotor, and rotating it until the holes in the case line up again. They are easy to rebuild your own with a kit and you can modify your stock case with heavier duty parts (rotor, and stator) to increase your rated out put while still looking original with correct date codes and part numbers. Just remember with greater power comes the need for better cooling.
