My kitchen light is not working. My cousin knows electrical work, but is not an expert. She states that it is staying "on hot" when she tried to fix it. It will some on, but the light switch will not turn it off. It doesn't respond to the light switch. We replaced the switch, so it's not bad. Any pointers?

There were three wires on the switch and where the light was. I think it was a yellow wire, a black wire and a red wire.

Most home wiring is done with cables, either plastic coated sheathed electrical cable or flexable metal BX. In either case you would not have a yellow wire.

Some homes, specially in the Chicago area, are wired with conduit inwhich case you might have yellow wires.

Other than the ground wire most siwtches only have 2 connection. The exception is for 3-way switches (3 wires), 4-way (4 wires) and speicality switches. There are specialty types of switches such as timers, motion switches, vent control fan switches, X-10 and other electronic control systems that might have more than 2 connections. But they are not common.

Ground wires are alwasy bare or green. Depending on the age of the wiring you may or may not have any ground wires. And even with the ground wires they may or may not be connected to the switch depneding on the age.

So 3 wires on the switch does not sound right, specially with the "yellow".

Give more details of how many cables or conduits are in the box and what wires are in each cable and which wires are connected to together and which to the switch.

Common wiring with one single pole switch would include.

1. One 2 wire (plus ground if used) cable.

2. TWo 2 wire cables.

3. One 2 wire and one 3 wire cable.

4. Three 2 wire cables.

All I'm looking for is a diagram to wire a simple light switch.

There is a lot more than just what wire to connect to what terminal.

You really need to get a book on basic home wiring.

Two that I recomend is Rex Cauldwel's "Wiring a Home" and Black and Deckers "Complete Home Wiring".

It's not uncommon for the insulation on the white wire to turn a bit yellow-looking with age. That's especially common on older wiring (newer plastics don't do this much).

So what you described as a yellow wire could actually be the white (neutral) wire. Thus a cable containing white, black, and red -- a real common arrangement for a 3-wire NM cable.
