Morning Gentlemen:
In the words of that Sony and Cher song......"and the beat goes on!!!"
Well, all I can say is that little exercise got me no further in getting that PS1 loco to move.
Went to Jaycar, got the bridge rectifiers (4 of them) as recommended (thank you Gunrunner John, Vernon, and Bruce) installed one of them to the back of the Z4000, and it did lower the voltage slightly, but not enough to make any difference to the loco.
Installed two inline (daisy chain) as per Vernon's diagram, and still nothing!! The loco still just sits there, and won't move out of neutral.
I am now leaning more toward what GGG has hinted about in his above reply.....a corrupted sine wave. When I shut the loco down, the shut-down sounds are funny. The sound of the diesel engine idling is missing for a couple of seconds, and then it comes on briefly, just before it disappears again, then the silence is broken by the faint "fart" sound.
This interrupted sound effect does not occur when I shut down using the Z1000. The loco sits in neutral (once I interrupt the direction of travel) with the diesel motor idling, and then slowly shuts down once I turn the track power off, followed by the short silence, and then the "fart". I think some of these early QSI boards are really finicky, and won't read the signal emitted by the Z4000.
BOTTOM LINE:
In the words of Harry Callahan (Dirty Harry) ...."A MAN'S GOTTA KNOW HIS LIMITATIONS"....and I now know mine!! Let's put this baby to bed, and I will learn to live with the couple of "funny" PS1 loco's I have. I will have to keep the Z1000 on the control deck, just to run these loco's.
Thank you one and all for your input, especially Vernon who has really stepped-up to the plate with so much knowledge and info on transformers.....it has truly been appreciated.
Good night all.
Peter.....Buco Australia.
