Little Fleischmann 4000 Diesel LEDs and DCC Decoder
Hi All, well I will show you what I have been struggling with/ working on
this little loco ready for a conversion to DCC and lighting , the original has no lighting.
Firstly after pulling it apart , I made a little template of the lights
Then out with the Blu tack and some winding wire and SMDs
these are wired in series
Adding in the Blue and yellow wire time for a test
All works OK , I sandwiched the wiring and SMDs between two sheets of polycarbonate
for the other end I decided to try some thin card instead - less prone to heat damage and glue the polycarbonate to the back
The Test Loco , looks OK Now to do the real thing
Next I Modified the back plate with a dremmel cutting disc , isolating different sections. quite a few cuts are required.
The motor body has to be isolated from the brush holder .
I cut two more groves later to have an area to solder the blue white and yellow wire with their resistors.
All the wiring in place and then the Orange wire came out..,
I had another M4 decoder , so I had a look where the wire was supposed to be soldered to.
Cut open some of the heat shrink and re-soldered the Orange back in place with the help of a magnifying lens
Put it on the Programming track an all was OK
So a bit more shrink was added to the decoder
I drilled some small holes in the Red body
and the lights are are attached with double sided tape at each end of the chassis , the wires running over the top
I forgot to take a few photos , after the drama with the Orange wire.
The decoder sits nicely next to the motor
Just visible underneath

Motor Back Plate Info
Conversion of Fleischmann Locomotives to DCC digital controlWhat is to be considered when converting locomotives generally and what characteristics do Fleischmann HO motors have for conversion ?
Basic DCC Principals
For controlling of locomotives with DCC digital decoders it is absolutely necessary, that the motor has no electrical connection to the body and power pickups of the locomotive.
Fleischmann built in its earlier designed locomotives motors, a metal, grounded motor back plate.

[1] =newer locomotives with insulated back plate (green)
The back plates 504713 and 504720 have a isolatable electrical link. With the change of the locomotive on DCC digital control they do not need to be exchanged.
Locomotives, in which the back plate 50 47 02 and/or 50 47 06 is built, receive the back plate 50 47 20 with isolatable electrical link during the new production.

Back plates made isolated by cutting the electrical link
If you look through my conversions there aare a number of backplates that can be modified by simply cutting the link between the negative motor brush and the part of the PCB that is electrically linked to the motor body/chassis.
Back Plates that can be modified with a bit more difficulty
Fleischmann developed FMZ digital in 1986 and gradually all Locomotives were given some form of insulated backplate
Back plates that are made with insulating material can be modified with a few cuts of a Dremel cut off wheel
It is important to isolate the Motor brush holders from the body of the Motor and also from the central bearing on the back plate
Pictures can be found in the "Illustrated Guide" on how to do this.
