Running conventional with Powermaster voltage control. One loco stays in forward when direction button is pressed. Other locos operate properly. On the test bench, loco operates properly when test lead is removed from center rail pickup.
I have seen elsewhere that the problem may be that Powermaster output voltage output does not drop low enough to trigger the e-unit when direction button is pressed. Is there an on-board work-around for this, since only one loco is affected?
