Bob, I have two K-Line "speed demons" that I would love to slow down by wiring in series. Is it possible that you could explain the process in layman's terms so that even I could do it? Thanks
gandydancer- the typical K-line diesel has two motors. The two wires coming off of the reversing board (blue and brown), that feed each of the motor leads (blue and yellow).
What I do is disconnect the 6 wires and clean up and re-tin the ends. Connect the blue wire from the board to the blue wire on one of the motors. Next I connect the brown wire from the board to the blue wire on the other motor. Finally connect the two yellow motor wires together. The motors in these are installed opposite each other so the need to turn in opposite directions for the loco to move in the right direction.
I use heat-shrink tubing on my connections, tape is ok if that is what you have.
Here is a recent discussion on the topic.
