I'm going CRAZY!! (LP)


I know this is SO easy, but I'm pulling my hair out!!

I'm putting in a light and a single pole switch. Power goes to light first, then the switch. Here's my wiring (checked 10 times, so I'm sorta confident it's wired correctly):

Line in from nearby circuit.

White from line in goes directly to fixture.
Black from line in goes to white on switch line. (And marked "hot".)

White on switch line goes to bottom terminal on switch. (And marked "hot".)
Black on switch line goes from top terminal of switch to fixture.

Both Line In and Switch Line grounds wired together, to ground screw on metal box.
Grounded also to ground screw on switch.

I have tried changing everything: It's a simple porcelain light fixture, but I replaced it anyway.

It's a brand new single pole switch, but I replaced it anyway.

Yes, I switched light bulbs.

I have looked in half a dozen "Electricity for Morons" books, and my wiring matches every time.

I have a proximity sensor that tells me that the Line In is hot. After connecting everything, it also tells me that the Switch Line is hot. When switch is off, black and white terminals on fixture are cold. When switch is on, both terminal are hot.....but no light.

I've already used 17 of my best cuss words, so if anyone has any bright ideas (pun DEFINITELY intended), I would SINCERELY appreciate it.

And my wife says she would, too.

Thanks!

Are you sure you hve 120volts on your "line from nearby circuit"?

Disconnect your incoming power and measure it using a meter - should read 120V black-to-white, 120volts black to ground.

Sounds like your wiring is correct, but something doesn't add up.

Welllll, I did check. Sorta. 2 of those swear words went toward my useless multimeter. I guess any excuse to buy a new tool is a good one, right? On my way to HD to grab a new digital multimeter now. Will check and advise.

Thanks!

While at HD, you may as well pick up a "Pigtail socket" & bulb. It comes in handy --and is very reliable-- for basic tests of power.
On your connections; Isn't it possible that you intermixed the White/ Neutral with the White/Hot from the switch. Therefore, both terminals in your lamp will have the same polarity! ( just a thought)!

Something isn't adding up so there must be more to this than you've discovered so far. Keep us updated, okay?

I would pull out the single pole switch and bench test it with a continuity tester. All of your wiring seems correct. Also not to sound like a jerk here but u said it was a porcelain fixture. Is it keyed or keyless?

Well. Interesting and interestinger. Black to white reads zero. Black to ground reads 120V.

And it's a keyless porcelain fixture (you dont sound like a jerk - that's something I didn't think to check!).

Tested the switch - zero to infinity.

So if black to neutral is NOT reading 120V, any likely suspects?

My white lead where I tied in isn't securely connected?
Something reversed?
Not grounded?

Getting out of my depth here. I may just end up tying into a different circuit.

And my wife is snickering. Good thing I haven't told her how much I spent on a new MM. :D

Open neutral. Follow with your non contact tester untill it reads no power, and that is the open.

Any possibility you connected into a switch leg for your source?

Good thought, but no, it's from a series of a couple of outlets (always-on).

Did you use the screws for the connection or the stab connections in the back?

When you tested where did u test? at the fixture or the switch? I would disconnect just to make sure of which wires are my feed.

Where EXACTLY did you test?

If you disconnected the power supply that you took from an existing circuit, and you tested the free (unconnected) black & white there, your readings would indicate one thing, but if your readings were somewhere else it would indicate other possibilities.



Draw a picture of the wiring you are messing with, and indicate exactly where you get the readings and what they are.
