Hi, I'm Mike and I'll be assisting you. Please stand by while I review your question.

Expert:  Mike G. replied 1 month ago.

Please explain exactly what you were doing, why and what you did after the spark.

Customer: replied 1 month ago.
Hi Mike, I was trying to change the light fixture in the hallway. Once it sparked, I thought it'd be a good idea to turn off the breaker. This is when I realized that the new fixture didn't work, and now the 2 bedrooms and my basement lights were off. I flipped off and on the main and each breaker individually. Even changed out the breaker that flipped off and replaced the light bulbs. Not really sure what to do with it now. Not even sure how the wires should be hooked up now.

I'm pretty sure it was the positive and negative, at the fixture, right after the breaker that touched. Can the wire be bad?
Expert:  Mike G. replied 1 month ago.

Do you have a 2 wire voltage tester? We need to test the wires to determine what is needed.

I'm goingoing to buy one now. I'll get back with you.
Expert:  Mike G. replied 1 month ago.

Very good.

Customer: replied 1 month ago.
Ok, I've tested them, I think correctly. And there's no power.
Expert:  Mike G. replied 1 month ago.

Test each wire to ground.

Customer: replied 1 month ago.
How do I do that?
Expert:  Mike G. replied 1 month ago.

One probe on the ground wire and then touch the bare end of the other wires one at a time.

Customer: replied 1 month ago.
Ok, no power
Expert:  Mike G. replied 1 month ago.

OK, go to the panel, remove the cover and test each breaker to ground.

All good, even the one giving me issues. I did just noticed that the one giving me issues is hooked up to something. I have no idea what it is or even if it's the lights. Maybe a balist?
Customer: replied 1 month ago.
This is hooked to it
Expert:  Mike G. replied 1 month ago.

That's a doorbell transformer.

Go back to the fixture opening and give me the count and colors of the wires in the box.

Customer: replied 1 month ago.
7 wires 3 white 3 black and a ground. These are the 2 I touched when everything went wrong.
Expert:  Mike G. replied 1 month ago.

This what you have to do.

  1. Connect the wires together by color. Blacks to black and whites to white.
  2. Turn the light switch off. Very important!!!
  3. Plug in a noise making item into one of the dead outlets. A vacuum cleaner in the on position will work.
  4. Go to every outlet working or not, plug something into it and wiggle the ug side to side. Listen for the vacuum cleaner.
  5. When it is heard, you found the problem connection.
  6. Open the box and if the wires are connected using the push back connections, that is the problem. Move wires to the screws.

Let me know how it goes. When that is done, you'll need to go back and change connections at the ceiling box to provide for switch control.

All my power outlets are hooked up to a different breaker. The only thing connected to it are lights
Customer: replied 1 month ago.
But what you are saying, is that I blew a wire loose somewhere?
Expert:  Mike G. replied 1 month ago.

Unusual to have only lights only on a circuit. Troubleshooting is a step by step process. A bad or lost connection can be on a working outlet and the loss is the connection leaving to the next outlet which is now dead. I suggest following my previous instruction to eliminate the usual failure first.

Expert:  Mike G. replied 1 month ago.

One more thing. Do you have any GFCI outlets that may have tripped. Check bathrooms.

Customer: replied 1 month ago.
No gfci outlets in the house. I just did what you said, and nothing. I check the outlets for power, and the first outlet, closest to the breaker is the only one that works. I took it out and everything is still connected
Customer: replied 1 month ago.
Not sure if this helps, it threw me off. But all the light fixtures have a white wire and a black wire connected for some reason
Expert:  Mike G. replied 1 month ago.

I have to put you on hold for a while. Doctors appointment. I post back when done.
