[sdiy] Power Supply

[Scott Gravenhorst]

To answer the question, it matters A WHOLE LOT
which is which.  Many circuits will self destruct
(read: buy some new parts) by reversing the power
supply polarity.

If you're digging around in the guts of an 
electronic device, a voltmeter (DVM) is a 
good friend.  A DVM can tell you "which is which"
and also how many volts...
