Plug up the new motor. Plug the wiring harness into the window motor. This will provide power to the motor so use caution. Lower your window back into its correct place on the wiring harness. Remove the tape or re-install your window. Make sure that the tabs in the bottom of the window are properly aligned to bolt it back onto the regulator. Bolt the window to the regulator. Using the bolts you removed earlier and the same extension, you need to bolt your window back to the regulator. Test your window. It should now move up and down freely when you press the switch.
If belt tension is correct, then the next item to check is the alternator itself. You now have two choices - you can test the alternator yourself with a simple test using a voltmeter, or you can have the test performed by a professional. If you choose to do the test yourself, then you will need a DC voltmeter, or a multimeter. Such a unit can be purchased at most auto supply stores, hardware stores, department stores, home improvement stores, etc.
