Having electrical problem with my 5520N. When you turn the switch to run position it blows the key switch fuse, #5, in the fuse block. I took the switch out of my 5400N and put that in with the same result which tells me its not the switch itself. Can't find any shorts or loose wiring anywhere. My manual doesn't have an electrical schematic so I'm kinda blind in that respect. The fusible link seems to be fine is there another relay or sensor that is malfunctioning that may be blowing the fuse? Would appreciate any help available. Thanks don't worry be happy and enjoy a good homebrew.
