Would appreciate some insight here. I have power coming in to a light above the mirror in the bathroom and then a switch loop going down to the common side of a 3 rocker switch and then back up from the top rocker. I wanted to use the other 2 rockers to power the light and night light up in the bathroom fan. I ran wires from the 2nd and 3rd rockers up to the respective black wires of the light and night light in the fan. There is a dedicated 20 amp circuit that runs straight to the fan. It powers the fan and also a GFI outlet. I thought I could take the white wires from the light and night light and tie them into the neutral wire for the 20 amp circuit, since it is right there in the fan enclosure. I know sometimes an unbalanced neutral can be an issue, but I thought it might be ok since the only thing on the 20 amp circuit is the fan and GFI. Didn't think a 100 watt bulb and a 7 watt night light bulb would add too much more. But, they don't work at all. The light works above the mirror, but that is it. So it looks like I shouldn't be doing this, but could someone please tell me what's happening here? Thanks!
