Thanks Lou1985 but I have done exactly that. That is why when the motor doesn't respond that I am stumped!

You must have the wiring exactly like it is depicted in Lou's diagram. The center screw of the 3 terminals is the field. The outer 2 screws are the brushes. If it starts up backwards, reverse the brush wires.

If you have the AC Commander in the tender, there needs to be a wire that connects the grounds on the motor to the AC Commander. You can't rely on the chassis grounds, Pulmor motor to engine chassis and the AC Commander to tender chassis. They have to be connected just like the diagram. I did this very conversion on my CSS 6-18011. Until I pulled it out and converted it to a DC Pittman motor and Cruise Commander. Also, make sure of the polarity on the caps on the brushes.

If you still cant get it to work, post up some clear pictures on how you have it wired and folks on the site will help you out.
