Circuit stopped working after lightbulb blew

I tried replacing the circuit, the switch and the light fixture where it all started. I have reset all the breakers. The voltage detector I have shows there is voltage on these outlets but no power. I drew a diagram the best I could to show what's on the circuit. I'm very grateful for anyone willing to help.

Diagram

Is the entire circuit dead or just part of it?

Do not use a pen type, non-contact tester. They are notoriously inaccurate and can make diagnosing a problem almost impossible. You need a multi meter or voltage tester where you touch metal probes to the copper of the wire to test for current/voltage.

Circuit dead

Yes. Nothing on that entire circuit will turn on. I got readings that there was voltage to some, but no juice anywhere on that circuit.

What do you mean be readings in post 4? Is it a light on/off, a numerical value or a pointer moving across a scale interpreted as a numerical value. If one of the latter two, what is the value?

Circuit.dead


It's just a beep, not really a reading. I think it's just picking up any voltage that's 12+. I normally would just use it before replacing a receptacle to make sure the breakers off. Many of the outlets will still cause it to beep, but not provide any power.

That indicator is not the correct tool to use to troubleshoot your problem. An inexpensive multimeter is what you need. Did the GFIs reset correctly?

Circuit stopped working

The GFIs won't reset. The indicator light on them doesn't even light up.

Everything was fine before, could it be the breaker?
How should i confirm that?

With a multimeter.

First Post

I just re-read my first post and saw it doesn't make much sense. I meant to write It all started when I flipped a light switch, it seemed like the bulb just blew, but the whole circuit went out and I haven't been able to get it back on.

Sounds like the problem is in the panel. Have you turned the beaker all the way to off and back on?

Looks like you only have that light on the switch. Are you sure the breaker wasn't already tripped before you turned the switch ON, and you only noticed the problem when you tried to turn on the light?

I had a problem with a breaker that all of a sudden tripped, and would continue to trip. Turned out the cable to my lamppost had frayed and shorted right where the cable exited my basement wall underground. Long ago I guess there was no requirement for a sleeve in the wall for cable protection, and so after many decades of slight abrasive movement, the cable finally wore bare and shorted.

Don't know though if that makes sense in your case.

But if it were me, I would check that breaker as recommended by joed in the previous post #10.

I didn't know a beaker had an on/off switch LoL

I haven't had to reset one in years (thank goodness), but I thought after a breaker trips you are always supposed to push the handle to OFF first - then to ON. Isn't the handle in the middle after the breaker trips? Seems to ring a bell.

Isn't it something about having to reset a spring by pushing the breaker to the OFF position after a trip? Could be wrong.

Ah something just came back. I believe you CAN'T reset the breaker to the ON position UNLESS you push it to the OFF position first. It won't stick in the ON position. Isn't that true? I seem to remember struggling with that and learning that the hard way, years ago.

But, that may all be fantasy -lol- very close to 80 now. Not only do I forget things, but I think I invent things that never really happened. That's even scarier -lol!

It's a simple matter to tell if a breaker is providing power. Reset the breaker OFF - ON and measure the voltage on the load side.

Resetting beakers is considerably more difficult.

The breaker definitely wasn't tripped beforehand. And yes I've tried resetting the breaker numerous times. My weekend has been nonstop with sports games, etc., but i bought a multimeter and will be doing some reading to learn what I can do with it. Thank you all for all your help....
