I'm trying to fit a Hornby decoder into an old Hornby OO DMU.
The DMU is not DCC ready so I'm hard wiring it.
I know that the red and black wires go to the pickups and the orange and grey wires go to the motor brushes.
The DCC documentation describes connecting the the wires to the correct "+" and "-" terminals. But I see that the DCC decoders conatin a rectifier . I assume this is true for the Hornby decoder as well. So my question is does it matter how the wires are connected? As long as the red/black go to the tracks and the ornage/grey go to the motor?
My question is prompted because the DMU, with it's DCC chip is very jerky and stalls a lot. Whereas other DCC locos are very smooth.
