Are you sure you put each pin into the correct hole? It has to go in a certain spot.

Questions...
1) did you isolate the motor from the frame? (Replace the bottom motor clip with the on the harness)
2) did you put a piece of electrical tape on the bottom frame of the loco (where it was ground to the silver metal so the old motor mount would contact the frame)?
3) Is there wires interfering with the drive shafts and not allowing them to turn or is the decoder interfering with the drive shafts spinning?
4) did you remove the stock athearn light mount?
I usually shorten those harnesses quite a bit and the wires are always a problem causing hang-ups with the drive shafts. Often I have to trim electrical tape and tape the wires to the top of the shell as I put it together and insert it into the shell as I close it with a mini screwdriver. Often it takes a few tries.
I can show you pictures of my units if you need. Let me know.
