What is ribbed wire?
Note that a ribbed wire is usually the negative wire on an extension cord. If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing.
How to tell if a wire is polar?
For those unmarked wires, you can first try to identify the polarity by looking at physical characteristics like color or texture. If you still aren’t sure, test your wires with a digital multimeter.
Where can I find wiring diagrams for my car?
Every car follows its own color-coding system for wires. There is no standard or international system, so find the wiring diagram specific to your make and model in your owner manual. If you no longer have your manual, look for one in a library or online. Or, reach out to a mechanic at a local shop or dealership.
Is copper wire positive or negative?
Know that the copper wire is usually positive on a speaker wire. On a standard wire used for things like speakers and amps, the silver strand is the negative wire and the copper-colored strand is the positive wire. These wires are often held together by a clear casing, so they’re easy to determine the polarity of each side quickly.
