    Check the ground connections especially at the back of the drum unit, I have had oxidation problems with the ground connections. I emery cloth sand them and then apply a coat of chemtronics contact restore to protect from oxidation.....Duke

        Drum Ground

        The drum is grounded threw the large round pin sticking through the rear frame. It lines up with the hole in the center of the drum.
