Default Re: Any visual difference between cut out and electronic regulator?

With a meter on regular cutout "B" terminal should be open to the case, and other terminal
The "A"should have resistance to the case, open to B

A diode cutout should be open to the case from either terminal, and should test like a diode between A,B, --- the direction of flow depends on pos--- neg ground

Never tested or took apart a fun project regulator, but I suspect some reading in all directions
