Landing light

[philbo10]

Recently bought a house and the landing light wont work , Ive changed the bulb and the light fitting , both upstairs and down stairs switches seem to be wired up correctly , when i put the multimeter on the celling rose i get 240v when i turn the switch on , cant work it out , help please !!! .

If you get 240V between the terminals to which the lamp is connected it will work.

I think a few more details are required.

Pictures of the rose and switch wiring may help.

What did you measure the Voltage between ?? L/N or L/Earth ?

If Live/Earth you may not have a Neutral there , possobly a loose connection in another Rose - check the Wiring Layout in the Loft ?

Maybe a dodgy Lampholder ?

yeah i checked it between Live / Earth , so in to the loft i go .

Didn't you test for 230 volts between live and neutral?

Could be a neutral fault.

Just try to see , where the feed comes up from Downstairs , then work out which is the 1st Light it feeds , then check the Roses (or jbs in the Loft) , it should be the one before the Landing Light , if all the others are ok , Possibly the Landing Light is the last Light on the Circuit

No Lucky im out of it now , no reading on the nuetral , when i put the nuetral to earth the light works as it should , when i was in the loft traceing the wires the nuetral wire goes down into a stud wall, but low and behold its not even conected to anything !!

I hope you haven't left it like that?

 

[philbo10]

I take it you mean connected to the earth , no i haven't , its all turned off now i'm not living at the house yet , so where does the lose neutral go to then ???

 

[RF Lighting]

You should never connect anything other than an earth to the earth.

Dunno about the neutral. You'll have to trace it and find out.

 

[Luckyphil]

It may go down the Stud wall to a Switch , where the Neutral may have been joined up with a Neutral from the Lighting Circuit , if work has been done a Connector may have have come loose/broken and the Neutral (Single ?) may have been "lost" in the Studding ???

Anyway if you have a Single Cable in the Loft , why not send it back to one of the other Roses on the Upstairs Lighting to pick up a Neutral for the Landing Light , it should work then .......

I`d also try to find where the Neutral finished in the Studwork , in case any termination of loose Wire(s) is required.
