Hi,

I realise that this topic has been extensively covered elsewhere, and
so I apoligise for bringing it up again... I have attempted to wire up
the fan I have to the light circuit. It is a JB arrangement and the JB
in question is the last in the loop. Therefore, the cables I have
coming in/out of the box a
1) Circuit Cable
2) Switch Cable
3) Fan Cable (triple+earth)
4) Cable to lights

I have connected the cables up as follows:
- Red from Circuit Cable, Fan Cable and Switch Cable
- Yellow from Fan Cable, Red from Cable to Lights and Black from
Switch Cable
- Black from Circuit Cable and Cable to Lights and Blue from Fan Cable
- All earths

The result I get is that when the lights are off, the fan is on. When
I turn the lights on, the fan stays on until the timer decides to turn
it off. I am therefore thinking that there is something wrong with the
fan, but there could also quite easily be something wrong iwth my
wiring :-). Is there an easy remedy for this, or do I need to send the
fan back?

Could be that the yellow and red are the wrong way round in the fan,
but then that still doesn't quite explain it.
Assuming all your wiring is correct then it sounds like a duff PCB on
the fan.
