I got a hold of fordcummins.com - Increase Horsepower with Ford Cummins Diesel conversion kits and bought a part that you put in the back of the dodge alternator to make it internally regulated and just hook up the wires like the Chevy, easy to do i think it cost about 40 bucks. i did this about 4 years a go and there has been no problems.
at first i crossed over all the gauges to use the Chevy stuff but the oil gauge would peg out and stick( i ruined three of those canister oil pressure senders) I then bought autometer gauges and left the speedo and fuel as Chevy. there is only one wire to the alternator and a couple to the battery and the rest are gone. good luck

The altenator has two ways of turning on. First is A type which is positive voltage exciting the field and B type negative or grounding the field. A 1980 ford regulator is A type which is the style of a cummins altenator. You have 3 terminals on the altenator the big one charges the 2 small ones are the field. Ground one of them and wire the other to the output of the regulator. Doesn't matter which small terminal, it's a coil. The regulator has 4 terminals A bat B ign C altenator D battery dummy light. Hope this helps

So there are 4 wires One is a ground it is grounded. Then there is one bigger one and two smaller ones a green and blue. So if I understand you correctly Hook the big one up to the battery, ground the green and hook up the blue to the output of the regulator. I do not have a regulator yet but if this is correct I will go buy one this weekend.

This is what I looked up for 1980 regulator. There appear to be 4 terminals I am guessing there is a voltage input the field wire and maybe a ground? Does anyone have a pic of what they did. I am trying to figure this out but have always been a chevy man and just dealt with there super simple alternators. So this is a new challenge for me
