My husband is wiring a GFI and separate light switch into the bathroom. The GFI also controls an outlet across the room – these components are working. He capped all of the whites together and we had 120v’s to both the main light (which we tested and it turned on) and the light over the vanity (which we tested with power meter). However, with the whites all capped together the lights could not be turned off. He tried a few different ways, but can’t seem to wire it so that the GFI and outlet will stay on and the lights will turn on and off. Do you have any suggestions or diagrams that you can share to how to wire the light switch properly so it will turn on and off? I have attached some pictures with the hope that they'll help. THANK YOU!! Edit: I have attached a picture of how it is hooked up right now (with this hook up, the lights do not work at all). <--- That is incorrect. With this hookup the lights DO work, just will not turn off. :help::help::help: Also - here is what my husband said: The GFCI is independently wired to the source. All's well with the GFCI and bridged outlet...power to both. Do the neutral wires for both light fixtures need to be connected to the source neutral? The source load wire is split with one leg to the GFCI and one to the switch. The light fixture loads are bridged to a common single wire hooked to the top screw of the switch with the source load connected to the bottom screw. The two fixture neutrals are wire-nutted to each other. Why are the lights constantly on, regardless of the switch's position?
