Ceiling light wiring help
recently we decided to replace ceiling fixture with led fixture. Upon removing old fixture we found two black wires on one side of junction box and three wires red-brown-black on other. The house uses fuses. We used tester and found that the two black wires created a 120 volt power source but when attached to the black wire on new fixture and black wire from other side we still got nothing and blew the fuse what am I doing wrong? All suggestions would be helpful Thank You

the two wires CONNECTED create 120 volts

Do your connections with the fuse removed. Then screw an incandescent bulb into the fuse holder. If the bulb just dimly lights then remove and reinstall the fuse. If the bulb lights at full brightness do not install the fuse.

Where are you located? US, or other? You did take a picture of how it was wired before you took it down, didn't you? Oops. Take a picture of the box with the wires hanging down so we can see it all. Also take a picture of the switch box with the switch pulled from the box. Remove the power first and post the pictures. http://www.doityourself.com/forum/el...your-post.html

yes a multimeter but without alligator clips just hand held sensors, and also I'm a little beyond taking pictures to keep track. ok so then the wire colors are red-white and black. ok so I guess what I am asking is to figure out which of the two black wires is sending power to the switch because ive tried these combos:
one black connected to two black (from junction box) then connected to fixture black and one black connected to white then connected to fixture white .
is their another way.
as for using the multimeter I touched the black wires simultaneously one to the red sensor and one to the black sensor that is when I got the 120 reading. When I touched only one there was no reading at all

Did you read my test connection? If so and want to be cautious use your multimeter to measure voltage between the alleged brown wire and the black wire in the same conduit. Red to "brown" should show ~120 volts only with the switch on.

pardon my ignorance in terminology but yes PROBES . If I do the afore mentioned "smoke test" and bulb is dimly lit what exactly does that tell me? In the same instance if it is brightly lit what does that tell me.
