Are you sure you checked the connections on the regulator. I put a new one in my 72 fixed most electrical problems but after a week the wires worked there way loose. Light crimp on the spade connectors and everything works ok again. In the winter the new regulator stopped working again and a good rap with tire iron no problem. Remember its 32 years old and all the conections are oxidized coated. I would also check the grounds from the frame to the battery and the engine if you have resistance between the engine block and the battery ground it will cause the generator to put max current out all the time.
