After all the testing and such I've been doing, a thought occurred to me.
Background: I am using PW ZW Transformers, properly phased and commons tied, and 10 amp fuses on outputs.
I am running on FasTrack with switches powered by separate power.
All power sources are using a common house circuit through the use of power strips.
Now to the question... I have not checked phasing of accessory/switch transformer power with the PW ZW transformers. Is this a possible stumbling block for the DCS signal?
