Lots of false information online about DCC ...
I have recently installed an ESU V4 Micro in my HOn3 C-25 locomotive and programmed it in the Lokprogrammer.
Everything worked well there.
Then when I tested it on the track yesterday, the light flashed ... and had a popping sound!?!
Also, the speed curve was completely out of whack, fast-slow-fast ????
I checked a little bit online to see what was wrong.
When it came to the flashing light, all the posts I found agreed that the LED wire had some contact with earth ....
So, the remedy according to them was to redo it....
However, there were many different theories on the speed curve ... Everything from the wrong drive step to a faulty motor(?).
After reading the manual a few more times, I came to the conclusion that the error should be that the decoder was not set to select drive steps automatically, which was easily corrected (check a box in the Lokprogrammer), and then the light worked perfectly.
The speed curve on the other hand .... Tested an auto configuration of the engine via CV 54 (value 0 & then press F1 and see the locomotive run away as shot from a cannon for a few feet and then press F1 again).
It made no difference.
Then I tried to change the starting CV (CV2) to 4 instead of 1, and look and behold, now it worked perfectly!
If I had listened to the "Internet professionals", I would have changed the LED without any benefit and in the worst case changed the motor....
So the bottom line is that you should read the flaming manual and test various things yourself by changing ONE thing at a time until you find a solution or answer.
