Next, set the selection knob to voltage. A problem using multimeters to test for voltage is that they typically have high impedance, typically 10 mω and can pick up ghost voltages. Hold the tip of the voltage tester against the side of the electrical cord. Use voltage tester to test electrical cords.

Three major wires (positive, neutral, and ground) run through most electrical cords. One red (positive) and the other black (negative). If the display screen reads voltage between 110 and 120 volts, the fixture is live. They are not dangerous voltages as no significant current can be supplied inductively in typical household wiring. The first step in testing a wire is.
