Wiring 4-Way Switches
Electrical Question: How Do You Wire 4-Way Switches?

I have a switch system for a ceiling light fixture controlled from 3 wall switches.

Here is the Problem:

I have a Double Pole; Double Throw; (DP/DT) switch that would not light the fixture at the same time I could light the fixture from 2nd switch. Then the 2nd switch also stopped working. I replaced the DP/DT switch (same terminals used) the fixture would not light from any of the 3 switches. With my volt meter checked the DP/DT switch and power in and out is now available. I replaced the other 2 switches ( same terminals used ) also replaced the lamp and no change- the fixture will not light; and also no voltage at other 2 switches or at fixture.
