Downlight fitting

[0ofiona0o]

Hi,

I have fitted downlights once before (a few years ago now) and so when I purchased my new lights from homebase (http://www.homebase.co.uk/webapp/wcs/stores/servlet/ProductDisplay?langId=110&storeId=10151&partNumber=866444&alt_cmp=859308) I thought it would be as easy as it was the first time....and I was very wrong!!

I have drilled the holes (x5) and fitted the fittings.....I have just been up in the loft so i could get a better look at the wiring and began the task of putting connecting the lights. When I switched the LX back on the lights worked...bingo...but when I pulled the cord to turn them off it tripped the fuse.

Do I need a transformer? Have I wired these incorrectly? The three mains wires which powered the single light before haven't broken the loop for the rest of the house so why is this a problem?

Please help as currently the upstairs of my house is very dark

Thanks,

Do I need a transformer?

Nope.

Have I wired these incorrectly?

Yup.

Need more information.

Picture of what used to be the ceiling rose would be good.

And select

"Light fitting has just been replaced and now the fuse blows"

Probably.

Often happens when people think it'll be OK to fiddle with things even though they don't understand how they work.
