Customer Question

I am trying to change a fixture (from late 1970s) to an LED. I removed fixture and show 2 black copper leads and no neutral. Not sure how to proceed.
JA: Thanks. Can you give me any more details about your issue?
Customer: I have mounted the mounting strap and attached the ground to the strap.
JA: OK got it. Last thing — Electricians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Hi, I'm Mike G and I'll be assisting you. What color are the house wires?

Customer: replied 9 months ago.
Copper (black)
Customer: replied 9 months ago.
2 of them

Do you have a 2 wire voltage tester. You'll need to identify which is the hot and which is the neutral to safely install the new fixture.

Customer: replied 9 months ago.
I have an ac voltage/detector flashlight. Is that the same
Expert:  Mike G. replied 9 months ago.

That will work. Test for a hot with the switch on. Identify the one that doesn't show voltage with white tape. Wire the fixture as required.

Customer: replied 9 months ago.
I tested and they are both hot.
Expert:  Mike G. replied 9 months ago.

That's why a 2 wire tester is better. Non-contact testers sometimes pick up voltage by induction on ajoining wires. Need a 2 wire tester.

Customer: replied 9 months ago.
Ok. I'll go purchase that then.
Expert:  Mike G. replied 9 months ago.

I suggest a Volt/Con type. It is all you'll ever need. Does voltage and continuity.

Customer: replied 9 months ago.
Thank you. I'll go to store.
Expert:  Mike G. replied 9 months ago.

You're welcome.
