Hi first post for me. I've bought a flat which has 5 lights on a dual wire suspended across the sitting room. There is a transformer at one end. It looks as though they are 50w.
The problem is that when I had the ceiling painted, the decorator must have knocked the lights because only 1 works (closest to transformer). I have checked all the bulbs in the working light and there are no problems there, I have also checked and tightened all the connections for the 4 other lights. Still no light from the other 4.
Any ideas as to what this might be or how it can be fixed? I'd like to avoid getting in an electrician if it's a common problem that's DIY-able.
