. . . . . and then medical help!
The bang test gets a bit old with a 3036 board - rewiring a fuse just to try again - we're spoilt with these new fangled MCBs you know!
 
nowt wrong with a 3036 fuse that a 2" nail won't cure.
 
@telectrix - back in your basket, bad boy!
How are the pups, have you been keeping us informed on the maternity thread?
 
Sorry to hear that of the two but great that other 3 have made it - a miracle in its own right. Smell them for me! I love puppy smell.
 
Join the red to the brown using a connector block.
Insert the two black wires into the L and N.
See what happens.

Yes that may work, but it does not resolve the earthing issue, not only is there no Earth connected in the ceiling but it is very likely that the switch is not earthed either!

Get an electrician
 
My advice would be to forget about trying to connect them up different ways in the hope that it works, and just call out an electrician.

You will likely find they'll charge more than if you had of just called an electrician to begin I know I would charge more.
 
Lighting circuits without cpc were the fashion in the UK prior to 1966 (13th Edition). So yes there are a lot still around. Obviously, the best fix, would be to rewire that particular circuit, but some customers either can't or won't afford this.

Another fix would be to run an earth from another circuit, but then you run the risk of that being inadvertently disconnected over time, or as I found recently an earth wire was used, bonded to a copper pipe.

There is another fix (following a risk assessment), that involves using only Class II luminaires and plastic light switches, then placing a pretty label on the consumer unit, indicating that particular circuit(s) does not have provision for earthing metal equipment. (Electrical Safety First - Best Practise Guide 1).
 
Not forgetting the pretty notice has absolutely no backbone in should you be faced with prosecution

What parameters would you base the risk assessment on and when assessment indicates a risk what measures would you put in place.
