I was cleaning my oreck air7 and saw that the green wire that comes from the Neg HV power supply was not hook to anything. The wire does have power so it hooks somewhere. Could you tell me where? The part # on the neg hv power supply is E130509 and 141790-001. The other wire is white and hook behind the fan. And is an open wire. It will not run with out this wire hooked up. deyoung@tds.net Thanks Don
