I bought one of these: **broken link removed** for general DIY usage. However, it doesn't seem to work. I am unsure if this is my own stupidity or if it was DOA.
I set the voltage to 9v and plug it into my little 7805 board, no juice. Tried it with an LM317 board, no luck either.
A multimeter across the jack shows 0v, even though the LED on the wall-wart is lit. I have tried multiple voltages and am definitely not drawing more than 500mA in any case (it claims to have auto-shutoff, probably via thermal fuse?).
Is the regulated PSU DOA, or am I wrong for some reason? I expect I should be able to test the voltage with the meter in this way.
