wires getting hot… why?

I got the dart running strong, the new cam is excellent, great power from about 2200 all the way to 6200 which is as far as I have pushed it. I had noticed without thinking that the amp meter had not been moving with the revs before we started the swap but the break in went smooth and everything was good till I drov4r home that evening I realized my battery was not charging. The alternator was fairly new when I bought the car and I don't understand why it gave out, but it did. So off to the junk yard and got a 60 amp from a van. The stock one was a 40 amp but there should be no problem, right? so I fired it up, and it's charging again, problem solved I thought, but every butt connector in line after the starter relay has begun to melt, and I've had to replace two. there ended up being some sulfation or corrosion inside the fusable link today for the ignition that had everything dead til I found it and moved the wire and then everything came on fine. But I know something is not ok here, why are my wires getting hot, and melting butt connectors, and why suddenly this sulfation on my fusable link? I don't have a manual for a 73 dart and have NO idea what to check or how... Please somebody help me, I bought a fire extinguisher just in case but I hope and pray I'll never need it...
