hi i am doing some work on an elctrolux central vac system # 1590 . at first i couldnt bypass all of ther iwring to see if the moter was seized up or working and finally figured out it was the brushes that needed to be adjusted. now when plugged in it wont shut off and the hose isnt even connected. I am looking for a wiring shematic of the motor,low voltage transformer, reset button and switching relay. I think the older gentlemen that owns it tampered with placement of the leads.
