that was so easy its insane, and it was clogged up with carpet strands, so the roller was tight, which created too much resistance in the electrical wiring which I think was the reason it burnt the wiring in the handle. so I replaced the hose/handle unit which I found on e/bay, I should have taken apart the handle and bought the new wiring kit for the switch. and fixed it myself. I read how to chg. belt, thanks
