I have, I think, lost my neutral. I have a 120v 1/3 hp. fan motor on what I think is a dedicated plugin ckt.The relay chatters loudly when I turn on the fan. I plugged in a light, & the bulb is very dim, but a plugin tester shows the ckt is good/ wired correctly. This is in a residence built in the late '50s & is a 2 wire ckt..I have crawled part of the ceiling looking for J boxes but to no avail ... how can I temporarily get this thing to work until I can hire an electrician to troubleshoot this problem?.. Could I scab a neutral from a nearby ckt to use it temporarily??.. P.S. I am NOT an electrician.. but I have worked with one as a helper while installing new wiring before..
