How do you tell the positive from the negative wire? Does it matter?

There is NO "positive" and "negative" in house wiring. Please do a web search on "lamp re-wiring". An improperly wired lamp can give you a bad shock (or worse) even with the switch off.

It matters how the wires are made.... If the wires are of a ZipCord, then the Ridge Side is Always Negative. The Round / Smooth Side is Always Positive. If the wire is Black and hooked to AC, then the Wire is Positive and White is Negative. If the wires are Red and Black (for DC Purposes), then Red is Always Positive and Black is Always Negative.

In another posting, the person talks of Brass and Silver Wires.... Brass is Usually (for me always) Positive and Silver is Usually (for me always) Negative.

I think it does matter. I didn't have any problem, because I was replacing the switch almost exactly like this. I just lined it up the same way. If you're working from scratch, sometimes there's a small ridge on one of the wires which let you know hot versus ground. Good luck.

it has been over a year since I wired the lamp but as I remember the switch has brass and silver wires so just connect them to the same wires in the lamp.

You could technically make either positive or negative. Just dont mix them up. If youre asking a question like this you might want to have your home theater system professionally installed. Personally I use the white line as the power positive red....black is clear ground.Good luck

Positive and negative from battery on one side; positive and negative to the 12v motor on the other side. There shd be very small print that illustrates which side is which

The polarity of the T connectors is standard -- the top bar of the T is positive and the post is negative. The labels on the diagram in the instructions are misleading since they are opposite to the orientation of the T sockets.

It doesn't matter as long as you make sure negative is connected to negative and positive is connected to positive. Same copper wire, just different plastic coatings. If it helps to keep everything wiring correctly for you, then use the blue stripe for all of your negative connections. You have made a good buy. Excellent speaker wire!

The red wire connects to the center pin, the black wire to the outer ring. As far as polarity, it depends on what being plugged into it. If you want a pos. center pin connect the pos power lead to red. For a neg. center pin, connect the neg. power lead to the red wire.

There is two stray wires for positive and negative. You can connect it to batteries. Connect it to a 12 volt source i.e. inside cab lights.

The meter supply with polarity connector, black and red wire, which represent minus and plus. The unit does not work at all if change polarity.i do not know what will happen if connect minus 5 v and plus 5 v. without ground. I assume it will not work or just show something wrong. Also, I take a look on surface mount parts and see that red wire via connector goes to diode. You may order this little thing just for few $ and blew up it under your desire in many different ways.

Wires hook to the posts on coil , one side is negative and other side is positive

If right light is red, wiring is correct. If Left is red, it has reverse polarity. If Both are red, there is an open neutral, and if both are white, it has an open ground. I use it in my 5th wheel to check wiring at campgrounds. It has instructions right on the unit.

negative or positive voltage is simply a reference to ground. reverse your power connections (leads) and you now have negative voltage. it does not have a dual output for both positive and negative voltagesgood luck

Yes polarity matters. I don't know which is + or - however. I tested it one way, didn't work, reversed the polarity, worked.

Usually the center connector is Positive. Use your DMM to determine the polarity.

Hello, yes there is 2 wires, black negative and white positive. Great light by the way. I have them as a spot light on my boat. Plenty of light output and durable.

Yeah. There's one wire for a positive signal and one wire for a negative signal attached to each other.

The switch contains an led. One symbol is - negative the other two are positive +. The two positives are the battery and load, the minus allows the connection of the negative side which will cause the led to illuminate when the circuit is switched on.

I don't know. There is no marking on the wire to indicate if it is directional.
