Subject: anode once refered to positive terminal not negative, of a battery?

In the old days it was thought that an electric current flowed 
positive to negative.  It is now shown to actually flow from 
negative to positive. Still, i was brough up calling the positive 
wire the anode and the negative wire the cathode, yet you seem to 
put this the other way around. I am now very confused and don't 
know if when talking about electrodes in electrolysis 
experiments, the red (positive wire) you call the cathode is the 
wire that would come up +6.00v on a mulyimeter, or the black 
(negative wire) that would come up -6.00v, for instance. v=volts.
What's going on??? Help me please to understand.
