Thank you for the suggestion thepollyparrot!
I never thought I would know how to deal with electricity, and I actually don't know much, but I think I am good at following instructions, especially when there is a diagram for it. The wires in the pedal are very easy to change if you don't mess up which side of the wire goes where, and you can figure that out when you open the three pin terminal.
I would send it to Jenny, but I still think it is cheaper if I take it to this dealer in my town. I opened the motor and it's in very good shape and it runs very well. I am just going to change the cord to be cautious because I know they can go worse on me anytime and can cause a serious accident.
I will let you guys know what happens. ;)
