I have ZERO experience with electricity and also just bought a new house and have ZERO money for a professional. I replaced a simple pull chain, medium base, porcelain lampholder and it will not work. The original fixture was coming apart and the pull chain had fallen out. I got a $5 replacement from walmart and followed the instructions (killed the breaker, black wire to copper terminal, white wire to silver terminal) and now it won't work (yes...I flipped the breaker back on). Please help!
