I just picked up a dc01 upright that someone had throw out and fixed it in 15 mins. No power. Mains lead busted at entry point. Unscrew one small screw at back of switch after opening dust collecter. Take off small panel. Remove switch (after unplugging!) remove clamps cut cable. Cut off a few inches. Refix., you will need one spade tag. Reassemble. 15 mins.
