Installing a sound decoder - 9
resistor for the backup light in the tender where there is plenty
of room.) After the wiring for the lights and the flat cable are
finished, you should have two leads to the motor (orange and
gray) and two leads to the track power (red and black) remain-
ing to be wired; the red lead will go to the loco frame and the
black lead will go to the draw bar.
The orange lead will go to the motor terminal which formerly was
connected to the frame or right rail. I always solder the black lead
directly onto the draw bar itself rather than the terminal or nut on
the shoulder screw – this eliminates one sliding connection that
often gets dirty or corroded, and causes stalling. While soldering
the lead to the draw bar (6), hold the contact wire with a clamp or
forceps so it doesn’t move, and make sure it is well-soldered and
fits snugly against the stud on the tender.

of firebox, and the flat cable to the tender can be seen
just to the left of it. Drawbar is down below it.
