I have my Ross turnout switch motors connected to the 14V tap of my Z4000. I have one block of track connected to Track 2 of the Z4000. No other connections are made to the Z4000. Both the turnouts and the track voltage work fine as long as they have separate grounds.
In order to make non-derail for the Ross turnouts work the ground for the switch motors needs to be common to track ground ground. As soon as I connect both grounds together the current on the Z4000 goes to 11 amps and pops a10 amp fuse I have fortunately connected in front of my Legacy Powermaster.
Question - Does the Z4000 not allow common ground between taps or have I screwed up my wiring somewhere?
