Guess unless I flat out say it everyone assumes the worst. When I said;
requiring a new chip from MTH
I meant that I got a new chip.
As for the issue, it's a well documented one, but one that gets missed because of how rare it is vs the common 3 clanks of death. Here is one document about it. It is problem #2, and possible locomotives that can have it are in table 2. In a nut shell, QSI was trying to make a way to allow you to individually run and control multiple conventional locomotives at once by using transformer button pushes to select the locomotives. It was so convoluted that MTH asked them to take it out. Well, they only took out part of it, the part that actually lets you select and deselect the locomotive, but left the selected and deselected modes in the code, with the locomotive always being in the selected mode. If you run it with a weak battery, it can end up getting in the deselected mode, but with the code to reselect it missing, it's stuck. The only fix is a new chip that ignores the selected/deselected memory location. GGG one time wrote a thread about his investigation and finding here, which is what lead me to contact him, learn how to trouble shoot it, and find out that I could buy a new chip, which I did.
