you cannot test a power supply with a volt-ohm meter other than
to tell you its on or off ...
	- wont tell you if its good or bad
	- but its a start ...

you probably should use a (storage) scope to look for glitches and
surges and load regulation .. glitches and surges is what makes
the "bad supply" go bonkers
	- and good load ( like the real system connected to the ps )
	vs a simulated load like a giant resistor 

fun stuff to test power supply ... especially when you do soemthing
wrong and let out the blue smoke, after that, it just wont work
if you let out the blue smoke ..
