no power after disconnecting light

Hello,

I have uninstalled a light fixture from my living room's ceiling, and disconnected the wires that were connecting that lamp. After doing so, I have lost the power in two other areas of the living room. Could it be the reason of loosing power the disconnection of those 3 wires?
Thanks,
iggui

Maybe. Do you really mean three cables not three individual wires? A cable is two or more wires in a metallic or nonmetallic sheath. Please post a picture of the wiring. https://www.doityourself.com/forum/e...-pictures.html

Here is the pic. Also, since the wires are all black, I cannot distinguish which one is the "neutral-white" and which one is the "hot or live" wire (this is how the instructions of the new lamp name the wires...)

Thanks so much,

iggui

I see two white wires, (white paint on the insulation) these obviously go together. Was this light fixture controlled by a wall switch or a pull chain?

I only see three wires in the picture. Are we missing one ?
Did one break off ?
Is there only one cable or two there ?
With only three wires present..... that box wiring should not affect anything else.

Pete, it is most likely knob and tube wiring. The neutral is in the box and spliced through to the rest of the circuit. Hot is probably a "flying" splice made in the attic or wall space. Not at all uncommon with k&t wiring.

iggui, wire-nut the two white wires and making sure the remaining wire does not touch anything re-power the circuit and see if that fixes the problem.

An open neutral splice would cause part of the circuit downstream to stop working since the return path is broken.
