My apology if I am posting in a thread that is too old, rather than starting a new one...
I think I burned out my front LED (Big Hauler 4-6-0 ATSF) locomotive at 20 vdc.
I had been operating it with the basic starter set power unit for years but switched to a much larger supply. The motor and the smoke unit are still working great. I have a few other Big Hauler locomotives that I will test at that voltage to see if anything happens to the LED. I am not in a hurry though for obvious reasons. I am now too blind to replace the LED.
I don't have a schematic but I bet the circuit with any resistor is designed for a lower voltage to the LED. If I can manage it someday I will have to see what is going on there.

I have sent several locomotives back to Bachmann (Thanks RJ!) to be repaired and I am so happy with the results. The latest generation motors and running gear are so fast as well as the other components replaced make the whole process a wonderful restoration of life to old treasures. Despite those who consider them not worth the price to get repaired, these Big Haulers will be around for decades more. I will be sending a couple more back to "RJ's Loco Repair Shed" soon!
