It depends on what devices are incorporated in the circuit. In some cases it does not matter which wire you connect to the positive. (A lighting system for example, where there are only lights and a switch) In other cases you may damage certain components by running current through them in the wrong direction (certain relays, capacators, resistors, etc). If you are unsure of exactly what the components in your particular circuit are, it is best to have a qualified electrician look at the circuit before you alter it.

What color is the positive wire on a lawnmower battery?
The positive wire on most batteries is red. If both are black, look for the positive sign by the electrode.
Does the red wire go on the plus sign on a battery or the minus?
The red wire is Positive, (+) and the Black wire is Negative. (-)
Is there a difference between black wire and red wire?
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
Is the gold or copper wire or the silver wire positive?
It doesn't really matter, as long as you connect them to the same polarity at both ends. Most people use the gold or reddish-copper wire as the positive, as it is the red terminal and the silver, or non-colored lead to the negative as it is black.

What is black on a car battery?
The black wire means negative and the red wire means positive if that's what you where asking
What are the positive and negative speaker wire colors on a 2008 pathfinder?
The positive speaker wire is red while the negative speaker wire is black on a 2008 pathfinder.
Is the black wire with white stipes on a battery charger a positive or negative?
Black = Negative Black + White = Positive Tried and tested.
What is the red wire and what wire does it go with when there are three wires black red and white?
Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.
If both wires for a ceiling light fixture are black how do you tell which is the live wire and which is neutral?
