Hi,

Have a ceiling fan controlled by the wall switch but no light originally
fitted. Got an add on light unit. Unscrewed bottom circular panel of ceiling
fan and found two unused wires, white and black. New light fixture has two
wires, white and black, connected through an additional pull switch.
Connected up white/white and black/black but the light still will not work.
Identical situation in another room. Any suggestions where to look? Thanks.
