Tonight I experimented with direct powering a Fastrack turnout but it didn’t work.
The track jumper was removed and power from a separate channel on the ZW+L was connected to the AUX IN position. I understood that I didn’t have to use the AUX GROUnD so I didn’t connect that at first. I turned up track power to 18V and the channel that the turnout was connected to was turned up to 14V. The turnout lantern did not illuminate and it did not respond to commands. Track voltage was 18V at both ends.
I connected a ground wire from the appropriate channel to the turnout AUX GROUND position. Track power to 18V and the ZW-L red light started flashing. If I left track power off and turned on the channel powering the turnout, the turnout worked perfectly.
Not sure if it matters but the turnout was not in a full loop of track. It was on the workbench connected only to a terminal 10” straight piece.
What would be causing the flashing red light? And did I understand correctly that the AUX Ground was not needed? If so, why didn’t it respond when the ground was not attached?
Any input would be appreciated.
