Lights only come on when main light is off..

[the glory years]

Hi
I'm new here so be gentle. I have a reasonable knowledge of electrics and did an essential electrics course and my 17th Ed a few years ago. I have just tried to add 2 new lights from a feed from a bedroom lighting rose to 2 extra LED mains voltage lights off a seperate switch. After carefully locking off the mcb etc and wiring as per loop in, switch and loop out to 2nd light etc, they would only come on (via the pull switch )when the main bedroom light was turned off...? I can't work out why..? I know it must be obvious but it's been a while since I did any work (I'm looking to get some shadowing or trainee work as well) Anyone help ?

p.s the main light did have a low voltage lamp in it if that helps...

Can you explain ? From the original lighting rose source you mean ?

swapping wires round will have one of three results:-

1. it works. 2. it don't work. 3. it goes bang.

i vote for no.3.

yes but wasn,t that what mcb,s were made for? save all that messing about with bits of fuse wire when you did get it wrong.lol

it was the thought of messing about rewiring fuses that mase us get it right first time

I was in a rush and couldn#t get me head round it etc..

try using that excuse in a court of law if your house burns down.
you should never be in a rush when working on electrical circuits. get an electrician in to do the job properly who will have made plenty of time to do the job without being in a rush and making the job safe

I'm fine, thanks anyhow. I know all of that, I know the problem now and I DO have enough knowledge to have left it all safely disconnected. I appreciate your concern though.
