I figured if a Volkswagen person didn't know the answer to this question no-one would!! When looking at power and ground wires for just about anything,which one is the ground----The black one with the stripe or the plain black one ??? Trying to solve an argument with a general post topic.
Thank you, Rick
Usually the one with the stripe is the positive one. So I guess which is ground depends on whether you have positive ground or negative ground - hahahahaha.

If you're talking about devices like power adapters (wall wart), you simply can't tell. Mfr's used every combination apparently.
For US household appliances (120V), the stripe (or ridge) is *always* the Neutral wire. It's called the "Identified" conductor.

And the one that tests continuity to the positive pole of the appliance is the one that's positive,......say on a radar detector or something,........................test to center post or tip is usually the positive....................there is one model(radar detector), and I can't remember for the life of me that uses the outer as the positive pole on a voltage adapter..................COBRA?.............FUZZBUSTER?...............I can;t remember.
It would help to know what the appllication of the discussion is though.
12V or other?Remove "YOURPANTIES" to reply MUADIB®
