Are you sure you have the LED wired the right way? LM's (and DCC decoders) are switched ground for the outputs so the blue wire (and the Blueline board) is positive and the green wire on the LM will be the neural/ground. Just checking...

I wasn't sure what you meant until I scanned in the Ring Engineering Installation Instructions (I hope Ring Engineering is okay with this) and could blow it up a bit and I then realized what you are saying. I have my resistor with the Green wire just as they show here. I am not entirely sure if the blue wire is what is connected as shown in the diagram. Before I clipped the wires for the light I had the locomotive powered up and the light worked and ran just fine with the LM3S installed but I could not control the light. It was just on. I pulled the white clip which held the two wires and then the light did not function. I then knew which wires went to the light. Assuming once is the "+" and the other is the "-" I soldered the resistor to one of the wires that went to the light and the other end of the resistor to the green wire of pin 6 as shown. Unless I have the locomotive wires wrong and it is important for the resistor to go to the proper wire I may have them wrong. After considering this and what you wrote I will switch the wires and have the resistor on the other one and see if that corrects the issue. I may have got it right with one locomotive and not right with the other 4 locomotives I am working on. 6 pin Rail Pro.pdf

It is important which wire goes to the common and which goes to the accessory wire. My bet is that you have them backwards.

A huge thank you to Bill and Tim for their input on this. Not being an electrical engineer I know enough to get things started but I did not realize that LEDs do have an input and an output side. Unlike incandescent lights, it does matter for LED lights. Having the resistor and the proper side of the LED makes all the difference. I switched the wires to the opposite side and this solved the problem and have gotten the 5 locomotives I wanted to get working finished, just in time for the next  5 modules Bill sent me which will arrive Tuesday. I feel that since I have gotten into Railpro almost 3 years ago (with lots of starts and long stops) I am now grasping the nuances of how to wire things up and program each locomotive for the functions you want. My next challenge will be mars lights and that will be a new topic. Thanks Bill and Tim, you guys helped me a lot.

William Brillinger:
Glad to hear it is solved!
