I am replacing a old table lamp socket the lamp with a base night light. There are 4 wires 1 back 1 white 2 brown 4 wires total. There are 3 terminals on the socket. Where do the wires go?

If you socket is the same as the one I am trying to replace then you only use 2 wires. 1 black, 1 white (power coming in) and the the night light is attached with the white and the other wire comes from one of the terminals from the socket. The switch is similar to the 3-way switch, 1 for the light in the socket, 1 for the night light..and 1 turns both on. No, mine is different. I have to use four wires. I took mine to the local hardware store where a friend showed me how to rewire it. I then went home and rewired the other one sucessfully. Thanks for the info.

Can I have 120 volts at the light fixture but the light won't turn on I have checked the wiring and changed the light?

If you have 120 v at the wires connecting to the light fixture the light should come on. Its possible the voltage is not getting to the inside of the socket. Carefully measure the voltage between the metal blip at the bottom of the socket and the metal along the sides. Be careful here. Its tight quarters and easy for the voltmeter leads to touch the wrong things. Before doing that I would try a third light bulb. I've gotten them bad right out of the package. If you have voltage inside the socket, then for some reason the light bulb is not screwing far enough down so the bottom touches that metal blip on the bottom of the socket. If you don't have voltage inside the socket then that's your problem and you'll need a new socket.
