Both alternators have the same number of fields. one. One has 2 field wires, and the other only one. The only difference in the circuits is where the regulator is located. The easy way is to ground the second terminal on the alternator you're installing. Here's some info dual field myth

Here's all you need to know: http://www.dieseltruckresource.com/pics/data/500/17307regulator2.jpgThe only difference between the 69/early and the 70/ late is that the field is not grounded to the alternator, but instead is brought out to two terminals. You can use a LATE (2 field terminals) on EITHER a late or early regulator, just ground one field terminal If you are using the 70/late regulator, hook as the diagram I posted. Hook the 12V source listed in the diagram to your old regulator ignition connection. If this connection has two wires, then one branches off to feed the coil ballast, IE this lead comes from the key and is an "ign 1" 12V source

All I get from that link is the diesel pages logo and a blank screen  In any case, no need to reinvent the wheel here. Even if you use the new style reg, the only change is the second terminal from the alt is wired back to the reg. It grounds there(through the reg). The first terminal gets key on 12 v. The existing key on ign lead at the reg, can do the same thing with the new style reg. You can't ground a terminal AND use the newstyle reg. The newstyle reg IS the ground for the charging field.

dave I guess I wasn't clear, what I meant was, IF you are using the early regulator with a late alternator, then you just ground one field terminal.
I don't know why the pictorial won't load, works fine here.
However, your answer may have been confusing to some as well, with your statements referring to "the field grounds through the regulator"
To be clear, what happens is that the late regulator REGULATES by CONTROLLING the current through the regulator to ground.
Nobody is trying to reinvent the wheel. Corvette already did that with their stupid directional and front/ rear wheels and tires.

Their site detected an image hotlink, and put up a 'bandwidth thief' image instead. Copy and paste this link into your browser, and you should see the picture.

See if this one works better. The ign1 (12V from the key in "run") feeds three things:
(possibly also electric choke)
feeds one terminal of the alternator field
feeds the ign terminal of the regulator
feeds the "high" side of the coil ballast for the ignition
