I partnered with one of our forum members on an SD driver's seat rebuild. After we got the seat out of the car we put jumper cables on the battery with aligator clips on the jumper cables and used the aligator clips to directly power the seat bottom for removing the spring from the motor frame.

Take it from the middle-aged crowd, work smart not hard.
