z4000 on start up

What is the s/n of the transformer with voltage present on start up?  Bet it was manufactured in 1996.  S/N's start with the month followed by the year:  eg:  0396xxxxxx  is /March 1996.

Nothing to worry about, just  "leakage".  To insure power is off the tracks it powers, simply torn the power switch off.

Try measuring with a load on the circuit.

Anyone know if the voltage leak is what is causing issues with the PS3 and Lionel unit?  I always question my wiring when a new layout is under construction but 8 other loco's (older Williams and a sunset) are working just fine.  Can that little bit of a voltage leak be messing with the brains?  

Is this the "wire a light-bulb in" thing?  If so, where?  It's a big layout... or will be eventually.
