Sorry about all the questions.
I am trying to learn and I don't know what I don't know at this point.
My third PS-3 Upgrade is a PS-1 Chicago and North Western E-4 Streamlined steam locomotive (20-3034-1).
The I finished the upgrade and it ran with the stock file that comes loaded into the upgrade boards. It added to the MTH Handheld fine.
I then down loaded the MTH upgrade sound file for this locomotive. It ran fine and the sounds appeared to be correct.
The smoke and electro coupler functions work properly.
The problem I am having is that the headlight, tender marker lights, and backup light on the tender do not operate either automatically when I power up the engine or from the handheld (basically none of the LED lighting works).
I downloaded the chain file for "O Gauge Steam with Standard Smoke. This made no difference.
I am trying to figure out what I have done wrong at this point. Any help would be greatly appreciated.
