Hello everyone,
I’ve done a lot of DIY on our 1910 terrace house since moving in nearly two years ago. Simple thing is electrics scare me.
I have just finished doing the bathroom, and changed the light for a nicer halogen frosted effect light (240V 40W). However, now the light keeps randomly blowing the bulb and so I’ve opened up the light and and was wondering if you could give me some advice on the wiring:
The middle (B) is earth looped together from all three sets of wires (I will cover it in green and yellow tape) A is the live (red) for wires 1 and 2 and C is the live for cable 3. D is the black cables for all three cables taped together.
I have a pull switch at the entrance to the bathroom, and an extractor fan that runs independently from its own pull cord, whether or not the bathroom light is on (so when the light blows the bulb the extractor fan still works – and I know it’s on the lighting circuit coz when I trip the lighting fuse downstairs the fan doesn’t work)

With the light switch pull cord off, electrical testing between A and C gives nothing, Between B and C gives nothing and between A and B gives 238V
With the pull cord on, testing between A and C gives 238V, as does A to B (earth), but again B to C gives nothing.
When wiring the new light I did (in my ignorance) earth to the earth, A (the two reds) to Brown and C to Blue
Is the wiring right, is how I've connected to the new light correct and if so why is my light blowing the bulb?
Many thanks in advance.
