I have lubed locos and made sure they ran smooth, but I have a more detailed question regarding this subject.
I know that most of the locos produced today have those evil plastic plugs used to make electrical contact on the light board and trucks. I know that many of you solder these wires to the appropriate tabs and I am going to do that.
My question is how do you relube the part of the trucks with wires permanently attached to the decoder/lighboard?
