Dave,
I will test Monday night when I get back to the system, using Direct Mode and making the preference changes as well.
Can CV's be read in Direct Mode, and is this true for all decoder brands, trying to idiot proof how to do this, without having to switch between paged and direct mode?
Two of the units tested, were N Scale, and there is no V5 in an N Scale package from what I understand, the drop in N Scale decoders will remain Selects for now. The Scaletrains unit is a rivet counter unit, so it should have a select in it, the Kato unit is a select per the instructions sheet and labeling of the box. The HO Scale Rapido SW1200RS, is a select from my understanding, I don't believe it's a V4, and while it's reasonably new, the production build is probably to old to be a V5, as I don't think that they were available at that point in time, but I will confirm on Monday.
None of the 3 locomotives tested, have keep-alives, based.on removing them from track power and headlights turning off immediately.
I will also try the test you did with track power to see if it does the same thing.
Regards
James

It sounds like a DCC system-specific issue, or a loco-specific issue.
Try turning off the caching options in Preferences->Roster->Programmer. (Enable Show CV numbers in tooltips but turn the rest off).
I assume the loco doesn't have a keep-alive?
Don't assume a Select, ScaleTrains also used the ESU Essential Sound Unit (a cut-back 5) and may now be using the 5. JMRI knows about identifying all these.
Just now doing ?some tests with my test decoders, I found that one Select I had been recently identifying correctly was having trouble (indicated by switching to Paged mode). Switched decoder tester to track power, made coupler activation noises and then went silent. Switched back to Program Track and all was well. Seemed as if decoder was trying to use program track power to activate coupler sound (ESU decoders remember function states) and upsetting CV reading! First time I've seen that particular problem.
Always use Direct mode with all ESU decoders, despite some OEMs' advice to the contrary.
