I guess my fingers are getting more tolerant of heat, since that works out to about 8 watts!Maybe not. Even a blown chips often has semiconductors inside. It's not a linear resistor so the "resistance" you read on your DMM is not the same as exists at +5V.
That is a possibility, but it measures 3.0 Ohms in either direction, with only a small fraction of a volt across it. I'm thinking it's pretty much a resistor now.
P.S. I've sent you personal mail regarding the PD.
