As I said to another 'poster' wish i had Â£1.00 every time this happens!
you are right about L's if only 1 light on this sw. they go together in spare term block not to light.
Need to find which black comes from sw. (it should have been marked as Red) If you look at the four blacks one may have been doubled over, 3 would have been together in N.term of light, the odd one on it's own in the L term
I am assuming light is 2 way switche. & if so at one sw. there will be a 3core/E & at other a 3 core+ a 2core/e the 2 core & e will be the black you need to identify at your light as the sw. L to it. you need to test between sw. black at sw. & each blk @ light to locate it.
