Hi, I'm Mike G and I'll be assisting you.

  1. Please give me the count and colors of the wires.

8 Wires
1=Black & White
1=Black & White
1=Black & White & Ground
1=Black & White & GroundYes 2 Wire Volt Tester
Customer: replied 2 months ago.
1=Black & White - 120V
1=Black & White - Goes to lights in Bathroom & Rooms
1=Black & White & Ground - Another Kitchen Light or From Switch
1=Black & White & Ground - Goes to Range Hood
Expert:  Mike G. replied 2 months ago.

OK,

  1. Connect all the blacks together.
  2. With the light switch on test all the whites to ground to see which show voltage.
  3. Turn the switch off and see which of the whites that showed voltage now doesn't.
  4. That wire has a paired black. Remove the black from the group connection and wire that white to the blacks.
  5. The black is the connection to the fixture. The white from the fixture will connect to all the other whites.

Ok Great, I am not at the location now but is this the set up iam looking for or are there further instructions after, can you send me a diagram
Expert:  Mike G. replied 2 months ago.

Just follow the instructions. With only black and white wires, one set goes to the switch. The white to the switch is used for a hot wire and connects to all the other blacks. It's paired black is the return from the switch and connects to the fixture. All the whites and the fixture white connect together. Take it step by step.

Ok so basically connect blacks, check which white has no voltage with switch turned off, remove its black from the group and add the that white with no voltage to the group of blacks, connect all other whites and the white from the light goes to the group of whites and the single black goes to the black on the light fixture correct. what if this doesn't work what is the next option?
Expert:  Mike G. replied 2 months ago.

There is no other option. With the wires you have it has to work. If there were red wires then it would be the only other possibility. Step by step it will work.

I tried wat u said and there was only 1 white line with low power I turned the switch off and there was none
Expert:  Mike G. replied 2 months ago.

OK, swap the paired black with it. That white powers the switch and the black will switch the light.

Customer: replied 2 months ago.
Ok and then connect all the whites
Expert:  Mike G. replied 2 months ago.

Correct.
