I have a wiring nightmare with two 3-way spotlights.
One light is simply wired off a black wire /red wire (earth cut short) and works fine.
The second light in the room has 2 cables coming out of the ceiling, each cable has a black wire red wire and the two earths connected together. Tried connecting two reds into brown lightwire and two blacks into the blue. Fuse blew on upstairs light circuit. What am I doing wrong please?
