Bathroom fan fuse

    Would a bathroom fan run off the same fuse as the light or would it be seperate?

    I've rewired the switch and fitted a new fan as the old one wasn't working and the new one isn't working

    So the fuse is my only idea

    Yes it's on with the lights, Is it a run on timer fan or just an on/off type.

    It's on a timer - turned to about 10 minutes

    Guess I'll have to recheck the wiring in the isolator but I'm 99% sure it's wired up right

    Two live cables are needed for a timer fan incase your old one wasn't.

    Disconnected everything and reconnected - fan is now working but...
    The timer is not working - if you turn the light off the fan goes off instead of staying on

    Can anyone confirm the SL and L wiring config from the light switch to the isolator
    I think I may have the SL and L the wrong way round on the light switch - would that explain it?

    I'm kinda guessing the wires as they are not marked, had to do a process of elimination to make sure I had the light feed cables then there was another live or switched live cable all by itself (this is probably where I'm going wrong - will switch it around tomorrow).
    There was already a light feed cable there that the electrician snipped off and isolated with insulation tape for some reason when the fan was initially installed
    The boxes are a mess of cabling
