@bmoran4 posted:Arnold, sounds like you phased your ZWs to your Z4000s but neglected to keep the grounds bonded connected. As such, you have 2 distinct "common ground" circuits. This isn't wrong, but introduces isolation which may or may not be desired, especially when considering track powered accessories.
The O22s pick up the common ground from the outside rail of the connected track.
So, does it follow that if I simply connected wires between a U Post for each of my transformers (two Z4000 and two ZW), and all transformers are otherwise phased, that all ground wires can be connected to one common ground bus wire without any problems?
