[COLOR="Blue"]Mod note: Member is in the UK[/COLOR] Trying to replace a bathroom fan, which is switch operated, rather than coming on with the light. Took out old fan, replaced with exactly same model, but can't get switch to operate, as fan is now always on. Two questions... What might be wrong? Is it right that the wiring in this diagram appears to connect live to neutral? Note, electrical knowledge is not extensive, so simple descriptions would be appreciated :-) Images show inside of fan, and connection in loft (with lighting circuits in left and fan connections on right). Thanks

I’m relocating and replacing a ceiling fixture. The new location is just a few inches away. The original circuit isn’t grounded, and need to be extended a few inches to reach the new location. I was going to connect a short 12ga Romex to it without grounding with wire nuts, but I’ve read somewhere that I’m not allowed to extend an old circuit with no ground, or install new receptacles with it. Are these restrictions applicable to my situation?
