Thanks gents. I followed the procedure for a lash up and everything works., including the F and R couplers correctly opening the A unit pilot couplers. Yay!
I noticed something about the directional lighting that seems prototypically correct, but I would like to make sure from you all that the units are operating correctly.
There is a small white reverse light on each unit. When I operate them as a lash up none of the reverse lights illuminate. Makes sense to me, they would only shine on the loco behind it (including the reversed rear unit). The headlights work correctly, switching unit to unit appropriately.
If I address each unit individually using the ENG# command and press the DIR but, the lights switch on and off as you would expect.
So I guess I’m just seeking confirmation....those reverse lights should not be on in a lash up whether going forward or reverse, correct?
