I looked at all the pictures and I don't see any bad components, wires that look lose or anything hooked up incorrectly based on those pictures. From what I can tell it looks like you did a great job, though it is possible something is loose and can't be seen in the picture.
I have located some troubleshooting information for you:
You can test the power to the motor from the spade connectors on the motor control board. You can also test the motor by doing the following:# ***** a 12-18 volt dc battery fully charged(like one from a cordless drill)# ***** sure it is fully charged, because it won't work if not# ***** the + and - to the motor red is + and black is -# ***** the motor turns slightly your motor is ok, if not the motor is bad and would need replacedIf the unit is dead, look close to the power cord for a breaker. It may even be a part of the on/off switch, make sure this hasn't tripped. If the connections are ok, your outlet is good and the motor tests fine, you will need to replace the motor controller.

If that information gets you and your mom up and running again (yes, pun intended) that is awesome! In that case, I'd really appreciate it if you would rate my answer. If you still need help, please let me know what you have tried and what the results were and we'll try to keep working out (sorry, I couldn't resist another pun) a solution!
