Hi, I'm trying to fix a ceiling light with a two light bulb socket and a simple glass plate that screws on below the bulbs. Both bulbs [2x tried new flourescent corkscrews] will flicker and fizzle when the switch is turned on, and so I'm going to start by replacing the sockets. I noticed that the new socket looks identical to the one on the ceiling except that it has a ground wire. On the old one, I only see a black and a gray wire coming down from the hole in the ceiling. I think it was installed in the 60's. Some of the insulation on the gray wire has cracked. Do I have to run the ground from the new socket up into the ceiling and find an attachment?
thx,
itchy
