Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

Is the black wire on a lamp connection plus or minus?
The color of the wire does not indicate its polarity. In electrical systems, the polarity is typically designated as positive (+) and negative (-) rather than plus or minus.

What color is positive and negative when installling a Kenwood CD player into a Peugeot 106 phase 2?
All you have to do is turn on the car into ignition area and grab a voltage meter. Find positive first, to do this, find a good ground spot on your vehicle, such as a screw or metal, than with the red meter wire, go around til you find one that makes the volt meter go up... that is your power wire. Now, go from that wire, and check for your ground wire. Hold the positive wire onto the positive spot on your vehicle, and use the black wire to check until the meter goes up, that is your ground. Now you are done.
