Although this is a fairly large diesel there
is very little room inside this model .I had intended to install a T1 decoder
but it was about 2mm to long. A TCS M4 was used instead. A M1 decoder could be
used as well.
1. First, remove the cover off the loco (as per the operating instructions for
the service of the unit) Lift the locomotive casing and remove.
2.At this point the original wiring and components can be unsoldered .Removing
the diodes isolates the lights from one side of the track power pickup.
Removing the RF chokes isolates the motor.
3.Following the decoders instructions the red wire -----to the right side rail
pickup orange wire -----to the motor circuit where the choke was black
wire ---- to the left side rail pickup grey wire ------to the
motor circuit where the choke was ----- yellow to the rear headlight
-------white to front headlight (the lights were connected in half wave mode
powered from the track).
4. Decoder is held in place with a small amount double sided tape.
