Bob,
The two wires (green and purple IIRC) are neither power nor ground.
Each is BOTH power and ground. But not at the same time ; -)
For UP, the green is +12 and the purple is ground. For DOWN the green
is ground and the purple is +12. Or do I have that backwards?
Actually, it doesn't matter. Just DO NOT hookup a ground wire to the
motor case!
I wouldn't use a battery charger to test the motors. It might work, but
battery chargers put out really "dirty" DC voltage. Meaning that the AC
voltage is chopped down and rectified but, if you look at battery
charger output in an oscilloscope, you'll see that it isn't steady DC
voltage.
Use jumper wires and your car battery to test, but be sure to make all
final connections at the motor. Sparks at the battery can cause a big
boom.

and
