You could then post follow up questions if anything else looks awry. I would want to open the other fixture and probably the switch to verify correct connections. If you find that the wires feeding the junction box are correctly polarized but the fixture is just connected wrong that really wouldn't give me peace, I wouldn't know if it was a single moment of inattentiveness or a pattern inability to follow safety codes. It is unlikely but possible that they could have run two switched cables from the switch, rather than one cable from the switch then one cable between lights. If not then you need to at least trace the cable back to it's source, probably the other light, but possibly the switch. This can simply be done with a no-contact tester or with a volt meter with one lead connected to the bare ground and the other lead testing the black and white for voltage. OK, I'm sure it's clear to you that the white should be connected to the white, and it should be the neutral.īut just switching the wires really is an incomplete solution, you know they did something wrong, but how wrong? At very least you need a tester to verify that the black is the hot and it is the switched wire. I’m not sure which of these delivers power from the house, and which go out to the lights and fan. There are 4 sheaths coming into/out of the switch box, each of which has one black wire, one white, and one ground. The switch on the right controls the light fixture in question along with another light fixture. The switch on the left controls a fan in the ceiling.

I stopped and left it the way it was because I wasn’t sure how to proceed.ĮDIT: I have now added a second picture of the existing wiring at the switch. First picture provided is the existing configuration.

Should I connect the new fixture the way it was previously, or follow the instructions? And what could potentially happen if I do it the wrong way? In case it matters: there is also another light fixture in the same room that is controlled by the same switch. However, when I detached the old fixture, I found the opposite: the white wire was connected to black and vice versa. The instructions (and every how-to video I watched) said to connect white to white (neutral) and black to black (hot). USA - I’m installing a new ceiling light fixture in a bathroom.
