Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.

How do you rewire a wall switch to control both ceiling fan and light. The switch currently furns the fan on and off but the light has to be controlled with a pull chain?

Open up the ceiling box and disconnect the blue wire coming from the light and connect it to the black wire coming from the fan. Be sure and put a wire nut on the wire where the light was connected before you removed it. The wall switch is controlling power to the wire where the fan is connected so when you connect the blue fan wire to that connection you will be sending power to both the fan and light from the wall switch.


When you connect earth wire in ceiling light does not work when connecting earth from light direct to earth wire coming from ceiling trips out when take earth wire out light works?

By earth wire I am assuming you mean the bare wire and that a black and white wire are connected to the light. If when you connect the earth wire and breaker trips then there is a short between black and earth. It could be a bad ground connection, an internal short in the light fixture where black wire "hot" is connected to metal on the fixture through a nick in wire.

Can you turn left when the traffic light is green or do I have to wait for the green turning light?

Depends. If the light has a sign next to it that says 'Yield on green light' it means you can go when the light is green and there is no traffic coming from the opposite direction that could hit you. If there is no sign wait for the arrow.


Can a ceiling fan be installed without the blue and green wires only the black and white ones?

Assuming the ceiling fan also has lights then that is what the second lead is for. You can tie the black & blue together and attach them to black lead in the lighting box. The light and fan will come on together when you flip the light switch and you have to use the pull chain on it for control. ALWAYS connect the green ground wire to the house wiring ground. This is a SERIOUS safety and fire hazard issue if you do not.
