You'll will have to find out which side of the recepticle is constant hot... plug a radio in a turn on and off the switch...(just an example).. open the recepticle and unsrew the terminal that is controlled by the switch and cap it off with a wire nut....add a jumper wire where you took the switch leg off from the recepticle and the constant hot....send a 12/2 or 14/2 (depends if your circuit breaker is 15amps or 20amps) from the recepticle to your fan box... hook up the bare coppers all together...the white condutor to the other side of the recepticle where your silver terminals are....finally hook your black conductor from the new wire to the wire that you have caped off like stated above...lemme me know if your confused..
I think you misunderstood what he wanted. He wants constant hot for the fan and switched hot for the ceiling fan light.
The existing receptacle has a tab broken between the brass screws it needs to be replaced with a new receptacle...don't mess with jumpering it. Determine which half of the receptacle is switched and remove the wire coming from the switch. Fish a 12/3
with ground or a 14/3
with ground (match the wire size to what's existing) from the attic ceiling fan box to the new receptacle. A 3 conductor cable will have 4 wires black,red,white, and bare ground. Connect the red of the 3 conductor cable going to the ceiling fan to the switched hot wire at the receptacle box in a wirenut. Connect the black of the 3 conductor cable to a brass colored screw on the new receptacle. Connect the white to a silver screw on the receptacle. Connect the bare ground with the others and to the green screw on the receptacle and to the box if the box is metal.
At the ceiling fan connect the black of the 3 conductor cable to the black of the fan. connect the red to the light... probably a blue wire. White to white and connect the grounds. If you need a diagram let me know.
