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?
