So positive is anode and negative is cathode. Is this referring to the power supply terminals or the actual electrode? Because in galvanic cells cathode and anode refers to the electrodes.
-
So that positive is anode and negative is cathode.
try again

Yep done :P

Your opening post is still incorrect.
Anode is -ve; cathode is +ve. Power outlets are electrodes in their own sense...the fundamental concepts are exactly identical...the outlet allows for +VE, -VE and Earth...galvanics are DC, outlets are AC...otherwise the setup and conduct of electrical current is the same.
-
I thought anode is -ve and cathode +ve in galvanic but reversed in electrolysis?

You're right. I misread your OP.
-
So is this simply referring to the terminals of the battery or the actual electrode such as Au that is connected to the battery terminals?
-
Anode is the impure substance; cathode the pure...battery terminals not relevant...see pic
