Wiring Problem

Hi. I'm fairly new to the forum and have spent a lot of time reading and learning so that I could learn to work on my barracuda and maybe help someone else. That being said I was wondering if someone could help me with my charging system. Last fall I decided to replace the wiring harnesses under the hood, the dash harness and replace the gauges with the redline reproductions. Ever since, when I start the car the ammeter goes to full charge and only comes back half way to the middle. The only time it will come back to center is with the lights, radio and blower on. The car is a '69 Barracuda that's been converted to MP electronic ignition. The VR is the old style with electronic internals and it has the round back alternator.
Based on what I've read in dozens of posts these are the results of my tests.
With key in on position...
Bat + to green connected wire at alternator 1.77
Bat + to fusible link .09
Bat + to red wire at bulkhead .24
Bat + to ammeter red .4
Bat + to ammeter black .43
Bat + to ignition switch black .47
Bat + to ignition blue .47
Bat + to ignition blue at inside bulkhead.53
Running warmed up bat - to vr case 0
Running with lights, radio and blower to vr case .1
Running at 1,500 rpm voltage at alternator stud 15.3
Running at 1,500 rpm voltage at battery 13.5
I also noticed doing these tests that the fused link and the short red wire leading to it get warm sometimes. I've been working on this all summer and am out of ideas. Any help is appreciated! Thanks
