Baffling Charging System Question

Hey 67, I believe it is in fact a broken isolator around the second field terminal, the one furthest from the output post of the alternator. I went through the entire system again, took off my regulator and made sure it was grounded, checked all my connections and wiring route and then changed the alternator to another one I had on the shelf that was working when pulled. It is about the roughest customer I've ever seen, but i didn't want to shell out the $60.00 for a new one until I was convinced that the problem was located. I am also leary now of rebuilt units off the shelf from regular parts stores because of the lack of quality to detail when rebuilding them, so I'm going to buy a rebuilt one from the Plum Crazy Garage, a company I have been using to core out starters and alternators. They are Mopar only, and although they only do date coded items, I will pay the extra $$$ to be sure my new one is rebuilt by a Mopar only expert, not some reman house that doesn't care!!! Thanks again 67Dart273 for helping solve this problem, it has been a pain in my side for way too long now!!! Geof
