I was changing a light fixture in my bedroom today. I took down an old ceiling rose which had the live wire, two neutrals, three loop wires, and 4 earths. I used the brass connectors and kept the wiring the same so all in all i simply connected up the live, neutral, and earth wire the the connectors from the old fixture. I tested the light before i stuck attatched it to its bracket and it worked fine, however when i attatched it to the bracket the brass connectors touched the metal of the new fixture and and blew the upstairs lighting. At first i thought it may be a fuse, so i bought two brand new but to no avail. Any ideas as what could be preventing any of the upstairs lighting from working?
You mention brass connectors if they are metal on the outside of the hot wire then you are creating a short. All your wires should be connected with wire nuts which are plastic on the outside. Insulate your wires and then try rechecking your fuses.
I can tell you what most likely happened but not any easy way to locate the problem. It sounds like you had something short to ground in the fixture which overloaded the circuit and burnt open a weak connection somewhere in that circuit. You description is much to complicated with many wires to be of much help from this end I would have to have a schematic of that circuit before i could suggest where to start
umm it could be the neutral is loose , you need to check it with a volt meter to see if its on then check each wire splice and i don't know what you mean brass connectors they should be plastic wire nuts
