1. Carefully remove the locomotive’s shell from the frame. Notice the orienta-
tion of the shell to the frame so that you can reinstall correctly.
2. The DZ125 has 6” wires that you will solder directly to the appropriate con-
nections inside the locomotive. The smaller size allows the decoder to be
easily installed in a variety of locomotives. The bare ends of the wires are
wired to the motor connections, power pickup connections and the lights
according to the following diagram. (
Figure 1
)
Note: Avoid stressing the solder connections of the wires to the decoder
board. If a connection is broken, carefully solder the wire to the board,
making sure not to contact any other parts or pads where it might cause a
short circuit.
3.
You are now ready to run your locomotive. The DZ125 is factory pro-
grammed to address 03. You can easily customize the address and other fea-
tures. See section “Customizing Your Decoder” that follows.
