Thanks, Chris.

At least I can solve my provlem for $15.95 plus delivery.

I tested the DC adapter part of my Sima SUP-2 "universal power
adapter" and found that the input ground and output ground are shorted
-- suggesting that it uses DC regulators.  No good.

I have a noname DC-DC converter used to power DVD players on
airplanes.  The input ground and ouput ground measure as completely
open.  How can I test it to see if there is enough isolation?
