Alternator Not charging....Voltage regulator ??

[SteedaLX]

OK....I got all my other issues resolved except one...the alternator is not charging the battery. I pulled the wiring harness out of the voltage regulator and with an extra wire ran a jump from the red wire(#2) to the dark blue wire(#4) on the harness.....the alternator then begins to charge. So I figured a bad regulator. I got a new regulator at the parts store. Nope still not charging with the new regulator. Can someone give me something else to try?

If this is going to be a huge pain...couldn't I upgrade to a newer alternator that has an internal voltage regulator? If so has anybody done this and do you have a part # or know what year I need. Thanks
