Kato SD40-2 motor problem

[Herc Driver]

Their warrenty is a good one I guess (although I have never needed to use it before). I've been getting a few emails from the staff at Kato encouraging me to open it up and look at it to see what's going on in there. I just got home, so when I get the time, I'll remove the shell and really see what I can figure out...why it won't carry power from the rear trucks to the motor. Should be simple enough...(famous last words).
