Andy Capp?Who wired the mirror?
Errgh?Andy Capp?
Am thinking, there's a problem with the heated mirror.
Try disconnecting it, see what happens.
Well this morning I turned up with my meters and did an insulation test on the upstairs lighting circuit L N -E was 1.2Mohm which is just scraping through. Volts must be inducing through the cables insulation. Took the timer fan back and fitted a pullcord model and an Rcbo. Advised the customer its a rewire. Thanks guys for the input.I can't see how a problem elsewhere on the circuit is going to cause this, based on the information we have, the problem exists on the S/L therefore must be limited to the switch and the wiring after it.
L-Nwas 1.4 Mohm. Its a dorma bungalow with aflat roof. Only access to the wiring is all the ceilings down as its got eyeball spots and no idea where the Jbs are.It might be just a L/E, N/E fault somewhere and rewires not required.
Previous tennant, I presume.Who wired the mirror?

What would you have done?Err pull cord model and rcbo? Really
What would you have done?

The 9 v was in every room upstairs when the switches were off.You've ruled out the fan as being the problem as far as I can see, so now you need to track down where the this 9V is coming from.
What have you measured the 9V with reference to, earth or neutral?
if you have a suitable multimeter then try measuring it with that, I suspect it will give a higher voltage reading.
I think the simplest explanation for a voltage on the S/L when it shouldn't be is that the switch is not operating correctly, so I'd be inclined to test that first.
Whats the answer then Einstein?Just scraping through?
Volts inducing through the insulation?
Advised a rewire?
Well that's a load of bovine excrement isn't it!
They don't need a rewire, they need an electrician.
I try not to post late at night (for me), but keeping it all to yourself is just selfish.View attachment 37809 and the best academy award and the winner for saying 9volts when the switches are off. goes to !
