Back in January I mentioned that I finally had all my track down and wiring done and was running some new engines that had waited years to come out of their box. One was a 6-11903 ACL F3 A-B-A of which I said, "Last test for the day was a Lionel Atlantic Coast Line F3 A-B-A. Still brand new but "waiting " since 1996 I think! Like most diesels with their wide pickup spacing, it sailed through everything without a hitch." (I was looking for places where pickup roller spacing might cause trouble.) I did not have my Cab/Base 1L yet, so was operating in Conventional mode. This beauty ran well.
Flash forward to the present and the attempt to run this loco in Command. Problem is it wouldn't. With the engine Run/Program switch in Run and the ZW-L in Command, the headlight comes on when the voltage is turned up to 18 with the Cab 1-L and it's Eng #1 ID is punched in. The B unit sounds work, but those two A unit Pullmor motors just sit there. In fooling around to try and determine the source of the problem I decided to change the engines ID number. Long story short, before I changed it, I found out when the Run/Program switch is set to Program per the picture in the owner's manual (switch isn't marked on the bottom of the engine), the darn think operates properly. So I thought perhaps the Run/Program switch was installed backwards or the drawing in the owner's manual was incorrect. But then realized if that was the case, how did it work properly earlier in Conventional mode with the engine switch in the Run (other) position?? The other interesting thing is that now it will not budge with the ZW-L in Conventional mode, with the engine switch in either position!
Any ideas? I am baffled. Thanks,
Bucky
