Rewiring a kitchen down light

[pappashacks]

Hello. I had 3 downlighting kitchen lights not working so I purchased closet to match. I took one down and took a photo of wiring. It at 6 wires. 2 L, 2 N, 2E. I rewired that light just a push in wire, clicked in and checked light that one worked fine. The other I remove only had 3 wires that clicked into place. I clicked them into L brown wire, Blue Neutral and Yellow and greeny blue Earth. Wired them up but when I powered up the fuse box kept getting thrown. All power off. Lite flashed on for a second and then through fuse box. So took the wires out and I had just clicked in and the light and all other lights worked. It's just this one throwing fuse box. I have placed a image up on this site showing the sequence the wires that click in run in.
L . E. N & N. E . L
I put the corresponding colour to the letter. Then switch power on and are everytime, it throws the power off.
Not to sure what I'm doing wrong guys, the 6 wired one I put in works. But the 3 wire one dont, throws power everytime. If I disconnect it. All the lights come on. So I take it, that its me not running the right wires to right place. Any help appreciated. Many thanks.

sounds like it could be the fitting at fault, have you tried putting the old one back on?
