Re: 1937 120C Current Draw

Hi, Pepe. Yes, I would love a copy of that manual if possible. Or, failing that, if you would tell me which version contains this information, I'll just order one from the internet. Here is what I have thus far:
On the picture, of my VRR-4005A regulator, I have labeled the terminals with what I believe to be the correct connections. On the upper right labeled "B" is the battery connection. Across from it labeled "A" is the line from the generator armature. Just below that labeled "F" is the line from the generator field terminal and the bottom where the regulator is attached to the body I have labeled "G" for the line connecting the generator ground.
Today, I removed the regulator and battery from my car and performed these tests. First, I connected the negative side of the battery to the "B" terminal and then testing the voltage between the "G" point and the positive side of the battery. I showed 6.2 volts through that circuit. I then connected the negative side of the battery to the "A" terminal and tested the voltage between the "G" point and the positive side of the battery. I received the same reading of 6.2 volts. I then connected the negative side of my battery to the "F" terminal and tested the voltage between the "G" point and the positive side of the battery and did not see any voltage. When connecting to the "G" point, I just inserted an alligator clip into the hole and insured that it was not touching anything else. These tests were performed on my workbench away from my car.
I firmly believe that this is the point of my current draw. Could this be a symptom of a damaged voltage regulator or one that has not been properly polarized?? Or, could this possibly be the incorrect regulator for my '37 120C?
Yes, if it would be possible for you to send me a copy of the Keep 'em Rolling Motor Manual, I would greatly appreciate it. Right now, based on these tests, I am at a standstill. If I connect everything as it should be, I'm afraid that the current draw would be too much prior to me attempting to polarize the regulator before something burns up.
Again, to all of you, I do appreciate your input and help in this.
