Another project slowly making it's way through the works at the moment is upgrading my newly purchased Intercity HST power and dummy car.
I've already taken it apart and cleaned the wheels and the motor as best I could, as the outer plastic motor housing will not come off without removing the wheels. Something I'm loathed to do.
And sprayed the cab control/seating pieces dark grey.
I also intend to DCC it by adding a hard wired harness for the decoder to plug into, add better directional lighting, cab light and driver, extra weight plus paint the windscreen wiper and add some paint to the cab controls somehow. Once I've worked out what is what.
I have ordered most of the componants I need to start the work which will arrive in the next couple of days.
I just need to get hold of 2 decoders now.
When opening the power car I noticed a weird wiring setup. (maybe it's just me)
The left hand tag (I've forgotten what it's called) on the motor (that holds the brush and spring in place) has a black wire that goes around the outside of the motor and connects to another tag on the other side of the motor. (the route shown in red)

Coming off that same side of the motor there is a diode that then runs to the right hand side of the directinoal bulb. (Obviously so the power only lights the bulb in the direction of travel).
What's confusing me is the black wire that comes off the left tag and goes around the outside of the motor and connects to the other side.
I have service sheet No.108 for the loco but it doesn't show this extra black wire.
I haven't DCC'd a motor like this before and the extra wiring is alien to me, let alond trying to figure out how to add the DCC harness.
Can anyone help?
Just for completeness, here is a picture of the front bogie on the power car.
