2 ceiling lights on a single switch. HELP

[soundster]

2 blacks together are tripping, they are only wires connected at present. as i mentioned i belive(d) these are for 2nd light fitting (as this is red, black aswell) and remaining one the supply from RCD, so i dont understand why they are tripping if nothing else is connected

p.s. the light shown already connected isn't faulty as it was tested on a socket

i have stripped back all the wires (just in case) inc the grey (grey inner from switch is now blue but was faded) reattached all 3 earths together and the 2 blacks i have and it still trips (with nothing else connected or touching!

Why not use your multimeter to find out which conductor does what?

upon much of a closer inspection, they were indeed shorting on second light, have removed the fault and both blacks are NOT tripping!!
