Ceiling light install gone bad--need help troubleshooting


I replaced a ceiling light in a bedroom a couple days ago. At first I thought i did it correctly because the turned on with the switch, but later that day, the light stopped working and will no longer turn on. It must be a wiring issue, but I don't understand why it would work at first and then stop working. The rest of the outlets, etc. on the same circuit seem to still be working.

Any ideas? I just wanted to see if I could get some advice before I open it all up again and attempt to reinstall. Let me know if anymore information or pictures are needed.

Thanks!

Three things to check----

Bad bulb

Dimmer switch with non-dimable bulb

most likely---loose wire nut

Thanks for the feedback, Mike. The bulbs are fine (already tested) and it's definitely not a dimmer switch. I'll check the wires. I actually didn't use wire nuts -- I just used electrical tape. But I'll check and make sure everything's still connected.

Shame on you for using tape---Now it will be a pain to check your connections.

Just poking fun-----Good luck --let us know the outcome.

Is the breaker on?

Just twisting and tape are not good enough to hold connections together. The connection will likely become loose possibly months or years later, heat up, and can cause a fire.

Do yourself and whoever else is living in your house a favor and NEVER make electrical connections like that again. Use wire nuts ALWAYS. If using tape over wire nuts (not common practice) makes you feel better, give'r. But don't use tape only.

YIKES.....

Thank you so much for letting me know! I had no idea that using wire nuts on lights was so important. The reason I had used electrical tape was that when I had taken the old light off, it was secured with electrical tape. It's an old house and I've only been in it a year, so who knows how long it was like that.

Anyhow, I took it apart again this evening, and sure enough, some of the tape had come off. I simply reassembled everything, this time using wire nuts and it works!

Thanks again! Invaluable advice.

Two things. Your lousy connection came loose, or some other lousy connection came loose when you moved the wiring around. Taped connections are fire starters. You need to check every connection in "that old house" and make them secure with wire nuts.
