[handyman fixes]

hi there to everyone. i am having trouble with my dda40x. it has two motors and one of the trucks fell out . i think that the person i bought it off of had taken it apart before. it will not run right the motors run opposite of each other. i cant figure it out how to fix it. any help would be great. thanks everyone.

I would have to see your loco to know for sure, but it may be something as simple as removing the problem motor from the frame and turning it 180 degrees and replacing it in the frame.  When dual motors run in opposite directions, it is a symptom of reverse polarity.

It sounds like the previous owner had the motors out of the frame and didn't get them re-installed correctly.
