External light

[Camalot]

Hi guys,

Having trouble getting an external light to work. I've wired it up via recommended way from an electrician which is a switch linked to the fuse board. Ive ran the cable to the light and wired the blue / brown / earth into the terminals as per instructions.

When i turn the fuse back on and flick the switch, my 'pen' detected power at all the cables via beeps, but the pir light never comes on. Ive checked bulbs etc but dont know what else to check

Any ideas before i have to call him out

Its one of them ones that come on dim when it gets dark, then bright when it senses movement .

I can take photos tonight. I was testing the light at 11pm in the pitch black, and i adjusted the sensor in all directions possible, the light never come on.

There is a light switch going into the fuse board, then a cable coming out the fuse board which wasnt in use. It was put there so we could add a garage light at a later date. Basically after a 5min call to an electrician friend, he said i cant wire my external lights to that switch, as there is no neutral, i need to connect my cable to the cable coming out the fuse board (which the light switch operates. So i joined the cable live to live, earth to earth etc.

Power is then fed to my light via that cable when i hit the light switch.

Hope that makes sense.

That is the other end of my cable going into my light.

A lot oo lights have an override where you turn it on, off, on to get it to stay constant, check the manual. Could be a faulty PIR. Have you tried altering the sensitivity and light levels on the PIR?

I've moved all the dials in all the directions they can go, nothing happened.

Nothing in the manual about an override switch.

I cant check individual wires with the pen as it beeps pretty much as i get close to the wires. I need a multimeter for that.

I've been told today to wire a plug to it and plug it in to see if the light is working, then eliminate that. So i'll be doing that first tonight.

I'll re-check all the connections again after work and see if anything is lose.

What a headache lol

Have you taken the little black sticker off the light sensor part of the PIR unit that B&Q lights all seem to have? This is so when you first switch them on they think it's dark and you can set them up but then after you have done this you need to take the sticker off for it all to work as the lights go off...

Nope, not touched any sticker, no note of this in the instructions either.

Surely if there was a sticker it would have lit up anyway if the sensor thought it was dark?

wiring at the fuseboard end sounds a bit funny
pics of your connections to your fuse board may be handy

Do you need a picture with the fuse board front plate taken off?

All i know is the end wire coming out the fuse board was just wraped up and taped off. The light switch at the garage enterance seems to operate this.

The breaker was on, as it also does the hall way lights.

Anyway, ive checked the connections in the junction box and they were lose, ive re done them and the light now comes on YAY.!!

Thanks for everyones help, such a learning curve !
