SIGWALLY........Here is some good reading on the AC Pullmore 773 type locos. http://www.justtrains.com/Hudson/773-1.asp
I seem to remember that on the ones I have, wheels cannot be turned by hand, however I think you can check for solid grease by turning the motor commutator by hand. I would lightly oil the points shown in Lionel 's instructions and then try applying power. If it is laboring to move stop. Good luck and congratulations. You are going to need some scale NYC passenger cars!
