Here is a copy of a page from the Delco-Remy service manual I've had for about 40 years or more, inherited from Dad's extensive library of reference material. It's not the same part munber, but the circuit is typical of most of the "A" circuit charging systems that use the regulator points as a ground. The "B" circuit supplies voltage to the "F" terminal on the generator and the field coils are grounded inside the generator housing.
