Yes, true, but for this exercise in a hmmwv, there is no AC output to utilize off a 200/400 amp unit.
I looked in the CE Niehoff book and see AC going to no where…I only see where they refer to AC in testing from the cannon plug.
Test phase signal into regulator (AC). Set meter to diode tester:
Connect red lead of DMM to socket C of regulator harness and
black lead to socket B. Meter should show voltage drop value.
Then reverse meter lead connections. Meter should show OL
(blocking).
This entire thread is just an exercise in theory, I am not sure what the OPs motivation is as he did not ever say.
I actually realized another scheme that would make it appear to be rectified (as you pointed out with the "blocking" in one direction when testing the phase cable and still actually have AC on the three wires on the phase cable, as stated above without the ability to use the field to regulate the 14V (because it is being used to regulate the 28V) and the necessity to independently regulate the 14V to compensate for varying 14V loads, regulating at the rectifying stage is by far the most desirable, that is why they are taking the three phases from the 14V stator into the regulator.
I wish I had a junk 200 or 100A alt to dismantle as I am not sure a second stator is actually necessary, (being drawn that way just to make sense when troubleshooting)I guess I will put a want in the classifieds cuz I am really curios now, or maybe someone needs one fixed, just makes no sense to tear down a perfectly good one just to settle my curiosity.
