As the owner of the tested device that started this thread, I have some details to provide. It is the "high current" version. I bought it new c.a. 2001. Roughly five years ago it suddenly ceased to pass current. Upon inspection, I discovered that a cat had peed on it, causing the IEC connector to short and burn. I replaced the connector and continued to use it up to the point when I sent it to Amir. I can even now smell the smoke that resulted from that short, and also see the black smoke stains. I believe Amir took this to be evidence of a recent event, understandably.
The ground is continuous through the device, and is connected to the case. There is NO continuity between the hot and ground. However, when powered, I also measure line voltage at the ground, so I assume there's some kind of inductive action going on. Lastly, when long ago the led lighted up, it continued to work. I replaced the blown fuse and the led turned off. None of this seemed to affect its operation.
My circuit tester indicates "hot and neutral reversed."
Hopefully this sheds some light on a confounding situation. Amir, you have my apology for putting you in danger. No one was more surprised than I.
