Case of failed engine ID# change

Close,  If the battery is low, the new ID can not be written so the old one remains.  The easy test is power up the track, start the engine up so sounds are playing.  Turn off power to the track.  IF the engine plays a full shutdown sequence the battery is adequately charged.  If it immediately shuts off, or abruptly shuts off after only a few seconds with out completing the shutdown sequence the battery is too low, or possibly can no longer hold an adequate charge.  There for DCS setting will not write to memory, nor will the train be able to come out of neutral in conventional.   G

For those that aren't familiar with this occurrence; the ID# is permanently written into the locomotive memory when power is removed. But, if the battery is weak, the new ID# will be lost and the locomotive will continue to use the previous ID#. The remote still has the new ID#.

You then wrote...

... implying that Keith's statement was not completely correct, which it absolutely was.  Why did you feel Keith's statement wasn't 100% accurate?

Adding additional information is fine and admirable, however, please let's not confuse the issue.

I thought the term "permanent" and "new ID Lost" were a little vague.  Thought what I said was just a little more accurate to what is actually happening.   More than just ID will not transfer.  Any setting changes like smoke off, or volume changes will not be written to memory either.  Which I know you know.  G
