I purchased a new LED flushmount ceiling light. I removed the old flushmount fixture that used two standard light bulbs. The old light fixture required two black and two white wires at the fixture, but the new LED light only requires one of each. This seemed like an easy fix, but then I took a closer look at the wiring.
This is a 1950s house and the wires are not quite the black/white/green I am used to. There are white wires, purplish wire (maybe a faded brown) and blue wires (ground? maybe a faded green).
Further, the fixture had a strange wiring setup. I attached a photo and a sketch I made to explain. In my sketch I used black to represent the purplish/brown wires, yellow to represent white wires, and green to represent the bluish wire.
1) There are three black wires that terminate in a wire nut. 2) 2 white wires in a wire nut with another white wire pig tailed to another wire nut. 3) This is other wire nut has the white pig tail with another white wire from the ceiling. Then there are two white wires that went to the old fixture. 4) Lastly, there is a ground wire (assuming the blue wire is ground) in a wire nut with two black wires that went to the old fixture.
My question - is this as simple as replacing the two white wires that went to the old fixture with a single white wire from the new fixture (and the same for the black wires)?
The thing that really confuses me is the blue "ground" wire with the two black wires to the old fixture.
I apologize if this post is a bit of a ramble - I am not an expert and not familiar with older wiring.
Thanks in advance for any help!
