I owe everyone a huge apology. I must have been testing phase the wrong way. I reviewed Lionel's YouTube video on testing phase and duplicated the light technique. Sure enough the Z4000 is out of phase with the two Lionel power bricks. The light was turning on when connecting red terminal to red terminal from the Z4000 to all three powermasters but not when connecting red to black.
I have a three prong into two prong adapter so used it to turn the Z4000 plug around in the power strip but this did not work for some reason. I tried turning the Lionel power bricks around but then they would not turn on the powermasters.
The one thing Mike ?Reagan's? video otherwise excellent did not touch upon was how to correct two power supplies out of phase with each other. I have a feeling I would need to have someone go inside the Z4000????
I still have a third Lionel power brick coming in, supposedly tonight so will hook it up to the third powermaster. For some reason the 14V terminal if used by itself will work with the power bricks on a common ground. If it does not I have a small Lionel CW40 I can try.
