Re: 1937 Voltage Current Regulator Voltage Draw

If the regulator is working and wired properly, when the engine is off there is a cut out contact in the regulator that opens totally disconnecting the battery from the regulator and charging system. Unless it is a faulty regulator there should be no way the battery is discharging back thru it.
If you have an AutoLite system there is an older and excellent training manual in the archive that details the function and how each part in the regulator and charging circuit operates. If your car has a third brush generator it even briefly touches on how those work. Delco works similarly but details are different.
Here is a generic diagram showing the basic postwar charging circuit and how the cut out contact isolates the battery when the generator is not charging. As mentioned, AutoLite and Delco differed in some of the details but the basic operation is the same for both.
