I have 1 light switch and 1 outlet in a 2 gang box in the kitchen. The old gfci outlet stopped working so I replaced it with another but it still doesn't work. The new outlet is gfci too and I can't get it to reset, nothing happens, no light comes on. I have a multi-meter with a non-contact voltage detector that I ran over the non-working gfci outlet and it lights up showing that there is voltage present. I swapped the white and black wires to outlet to see if they did it backwards, as they did elsewhere in the house, but it still won't work. What could be going on here? What are my options?
The light switch works so I was thinking of piggy backing from the light switch to the outlet or taking the wires from the light switch and putting them in the outlet and piggy backing to the switch. Does it matter which is first?
Also, what is going on with the grounding here? They didn't ground the light switch and they tied both grounds together to the outlet?
Lastly, how can I tell if the black wire is actually hot and white is neutral as it seems that they wired it backwards elsewhere in the house.
