Ah, well, it is no good measuring the voltage unless the thing it is
supplying is connected and trying to draw current. Connect a meter between
ground and one thumb and put your other thumb on a 12v supply. The meter
might show 12v (depending on how wet you are) but you wouldn't even light a
test-lamp.
