I’ve repaired and cleaned my Big Time mixer. When I took it apart I didn’t look closely at the wiper center contacts. Is the wiper arm closest to center supposed to ride on top of the clutch pad? I’m guessing it’ll make a ground contact thru the metal clutch plate but it doesn’t look like a solid contact. In the first photo you can see the center wiper with the 90 degree bend on the end. In the second photo you can see how the center wiper rests on the clutch. Is this correct or do I have a reassembly issue? Thanks!
