Hi
I've just replaced a non timer fan with a timer fan and the timer fan will not come on.
Original set up.
Wall switch to isolator to fan.
The non timer fan only used the brown cable and grey (w/blue sleeve) cable. Earth and black (w/black sleeve) cables present but left redundant - I assumed this was left as a switched live for later use.
New set up.
Live: brown to Red
Neutral: grey (w/blue sleeve) to blue
Switched live: black (w/black sleeve) to black
Results when testing
Live - signal
Neutral - hard to test as its so close to live
Black - no signal.
I've removed the black wire to see if that was causing the problem but fan still doesn't work. However, when removing this wire and then testing it produces a signal.
I also changed over live and switched live but that produced no results.
Not sure if the following information is useful but when i tested the isolator switch only the the brown wires produced a signal on my tester. The black wire was dead.
Any ideas whats going wrong? I guess I could test the fan with a corded plug and wire up just the live and neutral to see if the fan is working or not.
Thanks for any help.
Cheers
