Hello to all that read this. I own a Spectrum EMD DD40AX 16 Wheel Drive Diesel. Has anyone out there converted one to DCC? If so, could you please contact me so I can get instructions from you on how you did it. Thank you and will be looking forward to a response to my question. Mick

How does this dual motor locomotive behave with back emf control?
don't know, never set the load controls up, but it runs just fine on factory settings.
I did this conversion about a month ago and the hardest part was isolating everything and rewiring the whole thing. Robert pretty much summed up everything and I did mine the exact same way.
