Hi, this is my first post - please bear with me. I've searched around, but can't find an answer to this...
I am replacing an extractor fan above our bathroom. It seemed so easy. the old fan had 3 wires coming in: black, brown, grey (switched live, permanent live, neutral, respectively).
I thought I ought to check this before wiring in the new fan, but the results confuse me...
With the black terminal of my multimeter connected to the grey (neutral), and the switch off, the brown is 200V, and the switched live is 50V.
with the switch on, the brown is 0V and the black is 240V.
Indeed, if I wire up the fan according to the instructions (it's a Vortice lineo 100 with timer), the lights glow when the switch is off (50Volts worth), and the fan is on (I assume it's the overrun timer). When I turn the switch off, the fan turns off (0V in the perm live) and the lights are on (240V in the switched live).
I assume something is wrong further back? There is a junction box that these wires came from. Any help welcome!
