1. Carefully remove
the locomotive’s
shell from the
frame.
2. Remove the black
plastic cab seat
panel by gently
pressing in at the
sides.
3. Carefully remove
the plastic plug
that retains the
brass motor clips
and bend the
brass motor clips
up and away from the circuit board.
4. Slide the circuit board forward to release it from the clip on the locomotive
frame and lift the board off the frame.
5. Remove the brass pickup rail from one side of the locomotive, being careful
not to bend it. Wrap a small piece of yellow Kapton tape (supplied with the
Digitrax decoder) around the rail just to the front of the dimple (between the
dotted lines in photo, right). The tape should wrap around the outside edge
to ensure the brass motor clip is completely isolated from the brass pickup
rail when it is reinstalled. Trim excess tape on the INSIDE edge of the brass
pickup rail and reinstall it in the locomotive, lining it up over the position
pin. Repeat the process for the other brass pick up rail. (
