Hello, I am replacing a old outlet (non-gfci) with a new Leviton smartlock GFCI. I think I have a problem but not sure if wiring is backwards. I have 2 lines coming in and wired the 1st white & black to line connection. Wired 2nd black & white to load connection. The GFCI indicator light does not come on at all...(this is a new switch). The GFCI reset's and test fine, but the fact the light is not on at all tell's me something is wired wrong. One wire is coming from a light switch which I have hooked to the line connection. The other is going to an adjacent room outlet. ?
