How to Test Positive and Negative Wires When Wiring a Ceiling Light. 1  Turn off the switch that controls the fixture. 2  If you removed an existing fixture, pull the two wires formerly connected to it free of the box for easy testing. 3  Restore the power to the fixture and test the two exposed wires. If using a non-contact pen tester, hold the tip of the tester against each wire and press the button. The positive wire will light up the tester, while the negative one will not. If using a two-prong voltage tester, place one lead against the metal box or the ground wire (an exposed, solid copper wire inside the box) and the other against the exposed wire you are testing. If the tester lights up, or shows 120 volts, you have found the positive wire.
