Jerry - thanks for the help. My system is NOT charging - the cutout relay stays open at "idle" speeds of 1500-2000RPM. I am thinking that I should go back out and manually close the relay manually and check the voltage at the battery to see if it rises. Problem might be wiring - I did the whole truck myself, but everything else works. I just hate to replace a regulator with only a couple of hours use on it. But it was purchased too long ago to return.
Bartamos - assuming that you are still following this thread. I essentially agree with all you have to say about alternators. However, I am trying to restore this truck to look like it did in 1946. Yes, a 12V battery does not look like a 6V, but it is hidden under the floor boards.
