One of my locomotives is casue is making an odd noise, so i tried to oil it and replaces the lights on it with led, and now cant get the wire mess cleaned up enough the get the shell to sit on it right and something is preventing the rear truck from turning properly. and I also ound some of my decoders are appearently not compatible with my DCC system.

Can you give more details? what make/type of locomotive is it? what kind of decoder, what kind of DCC system, what did you do to oil it, how did you pack the wiring?
