It is now, after playing with all the alternatives for a few hours.  Note my earlier post:

 

GRJ, I've had 2 instancesrecently where the loco got garbled in the system.  Never figured out the cause, nor even how I cured it!!!!  Tried many things, and all of a sudden,it worked

Italics added.

 

Don't feel bad, even though you got GGG google-eyed.  I've overlooked details in posts also.

There is one thing that we may have overlooked, and that is probably very few of us like to disassemble an engine for ANY reason, to access either a battery or a BCR. And that makes me wonder if the principal cause of most electronics failures is operator or layout caused, or a problem inherent in the electronics. I believe that most studies have confirmed that if most electronics survive an initial "burn-in" period, they will last a very long time. And for a nominal extra cost it is possible to buy "Mil-Spec" electronics that have already been "burned in". (My info is "pretty old, but not ancient.)

Another reasonable conclusion is that, at some point either a battery of any type or a BCR will require replacement. And an ideal location would eliminate the need to either flip the locomotive upside down or perform any disassembly. MTH has located the battery charging port, when used, at the top of the locomotive. I think that is where the battery or BCR should be located.....with a suitable coal load or other type cover of course!

Points well taken. My two engines with battery charging ports are both MTH premier diesels, a CSX AC4400 and an EVO with the traveling lights. With regard to lubrication, I recently started to run a B&LE set of F units that have been stored for at least ten years as a display item. I had to replace all of the traction tires, which all split exactly where the tire contacted the rail. I opened them up to lube the motor where each motor attaches to the truck, and the grease was like new.

Hudson, these 21st century lubricants are certainly an improvement.  I've had to dig out rock-hard grease from 1950's Lionel locomotive.

 

I have replaced my 2.4-volt batteries with supercapacitors as they hit their life limit (7-10 years), so no longer have a need to access other than lubing or repairs.  Like yourself, I hate to disassemble a loco, and will admit that some haven't seen new gear grease in a bit.
