Fixture bad -- or "wiring?" How to tell?
So, a couple of years ago, I did a major home remodel. Electrician
was OK, but he loved to "screw with things," that did not seem to need "screwing with." And, he got a bit testy when I said I would install various fixtures myself, after he did the wiring, etc. But, now it is two years later. I have an outdoor light fixture...I use it maybe...once every two years. HA HA. Went to use it today. It does not work. Replaced the bulb with known good bulbs. No go. Is there a way to test the light fixture itself without taking it "out." It is sort of a pain to get to. It is a ceramic "pull chain" fixture, located in a SMALL enclosed storage area under a set of outdoor concrete stairs. It is out of the weather, but it does get damp in there in winter). I'm thinking the electrican, might have somehow disconnected it to the panel as he worked to connect the new cooktops, ovens, overhead fixtures in the house? I do have a $50 KLEIN digital "whatever those sort of meters are called" to measure current, but I am not very good at using it. So, any thoughts? |

If you put a bulb in it that you know is good and it still doesn't light, you've gone as far as you can go at the fixture without taking the fixture off. Other possibilities are an open breaker or GFCI on that circuit. If that isn't the case, then next step is to remove the fixture and see if you have power there. It is sort of a pain to get to.

Possibly corroding the switch. If it's bad, I'd replace it with a fixture suitable for an outside location.

Might be the best advice, yet. Sounds like the OP doesn't
know enough about electricty to troubleshoot, and find out what's doing. It is dificult to explain over the Usenet. Perhaps some web sites on electrical troubleshooting may help the OP? I'm being gentle and respectful (not insulting). Each of us who works safely on electric learned from someone else. In my case, from my Dad. The blackout of 2003 was not his fault, honest! Nor the one in 2006. -- Christopher A. Young Learn more about Jesus www.lds.org .. "hr(bob) " wrote in message ... Find a neighbor who is handy!!!! |

Fixture bad -- or "wiring?" How to tell?
OP Again:
Appreciate all your suggestions and I am not insulted by any, I am really pretty clueless on electrical issues. I was hoping I could do some magic mumbo jumbo without taking the fixture out, but I guess that is the next step. The house is 1970 vintage. There is a concrete staircase built as part of the house when it was originally constructed and -- like inside many homes -- there is an enclosed storage area under the stairs (access is through a small door). Romex (is that right?) comes out of the concrete inside the storage room and runs "behind" the fixture. I imagine there is some sort of "box" there. No GFCI in the house at all. Wait, I guess the electrician put a couple in around the kitchen sink when he was here, but that's all. I'll check them, but since those circuits are in use all the time.... I'll let you know how it turns out. |

Everyone has a totally clueless subject. Mine is drywall.
I'm worse than useless with drywall, spackling, mud, and so on. Best advice I'd heard was to contact your neighbors, see if anyone is handy with electric. I havn't read any insults or offense, in this thread. Which happens occasionally. If it would help, I'll flame you. Maybe in a couple days. -- Christopher A.

Try Candlepower forums. They would likely have a flashlight

If it worked after the electrician left and a new bulb won't glow, it's the fixture. Or: a) an in-line GFCI connected somewhere between the circuit panel and the fixture or b) a switch that the OP may not even know of between the fixture and the panel got thrown accidentally or c) there's a popped circuit breaker in the circuit panel or d) there's a disconnected wire between the fixture and the circuit panel. e) a breaker wire was not tightened down well enough and jumped There are probably more possibilities but without a helper with electrical experience, a fox & hound set and perhaps some other tools, it's probably beyond the OP's admitted skill level. Even experienced electricians can have trouble with "why doesn't this outlet or fixture work" once they've eliminated the basics. Even the hound sometimes can't follow where the fox (wire) goes, especially in older and oddly wired homes. My side porch light, at the diametrically opposite end of the house from the panel, is such a beast. The signal goes up, up and away, but never comes down again. No matter, I had to run a groundwire and neutral to is for X-10 anyway. So I ran a new wire from the basement up and sealed off the old one in adhesive lined shrink wrap. Have the potential to run an outside outlet from that line but I already have one nearby. I hate having porch lights or anything pass through an upstream GFCI. At $10 each or less, I just put them where I need them and either make that the end of the run or add outlets past it, and not through it. Bad enough trying to find blown breakers. I understand that's not codeworthy anymore. Why was it ever? My best guess is GFCI that it might be wired to has tripped. My second best guess is the switch in the fixture's bad. Third best guess is that the wire came off the screw that's supposed to hold it down. I've seen pros nick the wire enough with strippers that it eventually breaks, just from thermal stress, especially if they spread the nick even wider when curving the stripped end. -- Bobby G. |

I once changed outside outlet here thinking it was bad, before I realized GFCI in bathroom in addition was tripped. (No loss except to pride, outlet needed changing anyway, had the usual missing chunk near where ground prong fit in front.) Been there, done that. Was looking at a nightlight that my wife said was flickering and it seemed to only work when I squeezed it! Was just about to take it into surgery when I realized it had a photocell controller and when I was squeezing it, I was blocking the cell and turning the light on. Aha! Pride loss=10 points. -- Bobby G. |

I'm no electrician, but speaking from experience, I'd lay money on the pull-chain part being corroded. If you decide to take it apart, go buy a new one first. They are so cheap, probably not worth trying to fix. I'd also look at buying a weather rated fixture. I'd suggest a plain fixture and adding a switch, but pretty sure that is beyond your comfort level. That (corrosion) would be my first guess. Use a pencil eraser to "clean" the center contact of the light socket. Operate the switch MANY times. With luck you can cut through the corrosion. The next step is to pick up "voltage detector." These gadgets "beep" and and sometimes light when the tip is brought near a hot wire. These are completely insulated so you can poke them around without risk of shock or shorting something else. With the voltage detector at hand, take the cover plate off the switch and see what's Hot and what's not hot with the switch in it's two positions. That will give you a clue whether there is corrosion inside the switch or the wire connection at the switch is corroded. |

The little plastic testers you mention are great for helping to figure out what's live and what's not. Working the chain multiple times might work to clear corrosion, but sometimes even that doesn't help. My 60 year old Variac has developed hot spots where the voltage drops to nothing after a few seconds. Twistin the dial back and forth clearly reveals differences in the wipe to coil "friction" but only the top-most and lower most ranges work and don't drop out within seconds. Too bad it's the 50V range that's most useful to me but when I work in that range, the Variac passes current for a few seconds and then the attached bulb just flickers out. Around here, at least two things break every day. So far, my garbage can caught fire at 3AM, the Variac that controls the dog grate heater and the intercom failed. And the day's far from over. The old side door intercom (a three channel wired Radio Shack special from 1981!) stopped working after a period of intermittent behavior. The wire provided with the system (a very thin gauge stranded wire that's about the same as that found in one piece earphones) failed. It's got a miniplug on each end and I removed it all (it was stapled behind the baseboard) for a visual inspection since the fox and hound set didn't locate any obvious breaks. Two inspections under a magnifier found nothing. Now I am going to cut off the ends, one by one, and either attach new ones or just hardwire them in. I wish there was some trick, absent a TDR, to figure out where the break is. What bothers me the most is that I know I have at least two sets of replacement wires, and I remember putting them in a box labeled "Intercom Gear" but for the life of me, I can't remember where it is since I put it away 20 years ago when I installed it, using only one channel and just one of the three 100' "preplugged" cables that came with it. -- Bobby G. |

Unless OP hasn't found it, there is no switch to pull the cover plate off of. I think he meant say "to pull the fixture off the junction box" and check what you can see on the pullchain switch mechanism wiring and mechansim. That tends to vary from fixture to fixture. On mine you unscrew a porcelain retaining ring and the whole switch body pulls out. I'd also look behind it to see if the wire's still under the screws and not broken off at the strip juncture. That's a common failure point and a spot where I've been failed by the AHJ more than once. It's easy to badly nick the wire and not see it, especially if you're blind as a bat. I use a very bright LED headlamp for wiring that sort of stuff now because of aging eyeballs and a known bad hand when it comes to nicking romex while stripping it. . -- Bobby G. |
