it is a 70 duster with points .

i am talking about how they plug into the altenator. i have 3 wires. one has a loop, and i know it goes to the stud with a nut on it. then i have a blue and one green wire that clip onto the altnator. witch one is field and which one is ground? or are both field?

I believe that on the 70 up alternators they have two field wires on the alt. as opposed to a single field terminal on the 69 down. Now, it makes no difference which wires plud on the field terminals of the newer style like yours as long as you get the bigger battery wire connected to the battery terminal of the alt.

The two field terminals are just one big connected loop of wires with-in the alternator and they don't care which way they are hooked up. Green to one terminal and the blue to the other. Now the question is do yopu have at least access to a volt meter? You need to make sure the alternator is not over charging the battery. A few here have asked the voltage, you need to know what the output voltage is at the battery terminal of the alternator. It should be no more than 14.5volts. It likely won't be that high at idle but when raised above say 1,200 RPM it shouldn't go any higher that the above voltage.
