    Hi, wondering if you can help.
    Had a guy who said he was an electrician literally do a “simple” job, replace an old brokenOutdoor pit motion sensor with a new one as the lense was cracked - on my garage which has 2 lights connected to two light switches in the garage.

    The lights are on all the time but I can hear the sensor going off and on?

    I have opened it up and I can see the attached wires.

    looking at the old one, it also had an earth connector in it as well.

    he’s not bothered with the red terminal as you can see.

    anyone know what he’s done wrong?

    Guess is that one cable is live supply and the other it to light? Identify which one is which and move the brown to the red connector. Also join the earth with a connector block

    Are you sure he was an electrician?

    Hi thanks for responding

    he claimed he done electrics. He won’t be coming back to fix it.

    There are two browns and two blues, both look like they come from the two individual lights I “guess”

    So I have an electric tester which he left?

    do I just grab one of the browns, any one and stick it to the red...?

    Read the instructions ...

    That red could be any number of things - for example a switched output to another light, or an input , or ... so RTFI

    Its a standalone sensor isn't it, looks like this one.

    Absolute **** at the best of times but none the less the one above isn't wired correctly, one brown goes in with the brown and the other goes in with the red, 2 blues with the blue and the earths connect together, think there is a little terminal for the earths on the backplate.

    Just following up. Just grabbed one of the browns, and put it in the red one (no idea if it should have been the other one)

    many way, at least now I am able to switch the thing off more or less. Before I couldn’t.

    the sensor still clicking but the lights are not going off - just permanently on?

    i “thinkL they might have been set up so at either of the two wall switches, you can over-right the sensor I did have? Wonder whether I haven’t purchased a like for like sensor which is functionally wise similar?

    think it was originally : Timeguard NSLB2000 PIR Lighting Controller Switch 180° (Black) - Packaged as Newlec NLPIRB2A https://www.amazon.co.uk/dp/B073S4WTNS/ref=cm_sw_r_cp_api_i_P0XiEbH6FZK0Y

    I can think of a few words for the chap that left the job like this but he is not an electrician. Neither am i but I would not have left an energised circuit with earth like that irrespective of anything else. Certainly he does not merit payment, possibly a bit of training but no folding stuff
