OK, I'm stumped
I have a wall-wart rated: 120V AC input with an output of 9V @ 500mA.
For some reason my multimeter (which I have checked to be accurate) is reading nearly 23V DC. Unplugged after nearly a week it was reading 3.xV.
What's up with that!
essentially it has primary and secondary turns, 4 diodes, and a capacitor. Since it is unreliable I opened it. Nothing looks toasted.
Any possible explanation for this?
