Barry, I have found that a new battery is cheap insurance against seeing a locomotive back again on the workbench. When dealing with old boards it is always wise to dump the white battery. I see more people recently that just want to go to a BCR and be done with a battery issue. If someone who is still sporting an old white battery does not want to go new, I refuse to work on the engine.
As you know, I still have many 5V locomotives running on my layout. I have dumped all the white batteries.
The only help with old 5V boards we as forum members have available is forum member GGG or do the 3V replacement.
I am still trying to figure how some people who do not own a meter can look at a battery and state it is good. What a great talent to have.
