Anyone help with my problem?

Hi guys. Im having a right carry on doing the simple task of putting a new light up. My house is old so has the old wire colours, when i have installed other lights in my house i have found 2 of each required wire positive, neutral, earth. In the past all i have done is twisted each pair together to make one and connected up and everything fine. With this light it keeps blowing the fuse in the box, i noticed it had another block in the terminal for the unswitched live so i thought i would try one live in there and the other in the switched live then if that did'nt work change them round but nothing? Anyone help??

I'm assuming that by old colours you mean red and black.How many of each colour do you have? If there are 3 blacks and 3 reds then there is a fairly good chance that one of the blacks is a switched live in which case you will need a multimeter to find out which one.
Always remember how the old light was wired up.

Interesting name by the way

It was'nt possible to use the old lights way of connection as it was on an old light fitting which this modern light wont attach to. As i said there are 2 earths (copper), 2 lives (Red), 2 Neutrals (Black)

If the light is on its own (ie no other light comes on with it) then it sounds like the light is on the end of a loop in system.The 2 reds are permenant lives and both go in the block on their own.One of the blacks is a switched live and one is a neutral.Now if the switched live is not, as it sounds, identified with red sleeving then you will not be able to identify it without the use of a multimeter.As long as the fitting does not have Edison screw type lamps or there are no other switches on the light then it doesn't matter which way round you put the 2 blacks - 1 into the switched live terminal and 1 into the neutral terminal.Ideally though it is best to find the switch wire.
Don't forget to connect the earths to the fitting if it is class 1.If it is class 2 (square within a square symbol) then connect the earths together but NOT to the fitting

Hi there thanks for your response. I have tried what you say with one black in neutral and one in switched terminal nothing at all happened, then switched the two blacks around and the power is on permanently now. Should i put one of my red lives into the switched live and pair the switched black with the other red live and put them in the live terminal???
