I have a 1965 Dart 270 that I'm working on and just recently I installed a new 100 amp altenator with an internal regulator to replace the 60 amp it originally had, during that I followed the wiring diagram for the car to take out some wires I didnt need any more as well as the external regulator now it doesnt even want to turn over, do I need that regulator or is there a work around?
