Is it possible to wire a hall light in a 4 way set up with lighted decora switches. The master switch box [the 4 way] does not contain a ground. Regardless of how I wire the 4 leads to the 4 screws of the 4 way switch the hall light will not work correctly from all three locations, and depending on the way I wire the 4 way switch some of the other 3 way switches in the same circuit will not light while in the off position.
