Ceiling light stopped working! Help?

Yesterday, I replaced a ceiling light in my home (lots of knob & tube, the house is 112 years old), this light seems wired on a newer circuit. The power comes into the ceiling box, and attaches to another wire that runs down the wall to my switch.

The new light fixture ran all day, and then was shut off for a few hours. I went to turn it on and the light bulb flashed like it had just burnt out. I replaced the bulb and still nothing. Today I replaced the wall switch, and still nothing. I even tried attaching another fixture to the circuit, and stll nothing.

Any suggestions, other than calling an electrician? I consider myself to be an above average handy-man, but hardly an expert. Am I over looking something?

Thanks everyone!

 

Did you check to see if you still have power at the ceiling box?
Maybe it blew a fuse or circuit breaker.
I would check for power with a voltmeter at the ceiling box. Power should go from there to one side of the switch. Then it should go thru the switch when it is switched on and back up to the light.
My guess is that you will find no power anywhere and will have to chase down where it is supplied from.

 

No power at the ceiling box, and the fuse didn't go.

If I chase down where it's supplied from, what am I looking for?

I can't imagine why it would work all day and then suddenly... poof!

 

If you know where the power to this box comes from,
work backward looking for the last junction that has power.
You should find a loose connection somewhere.
If you have power at the fuse for this box, and that power goes out of the panel and thru the house to various things that it powers up, the wire must either be broken somewhere (which is highly unlikely), or a splice / wirenut came loose somewhere on its way to this box.
