I need some help! I was mowing Saturday when I shut off the engine I heard a click. I went to restart the tractor and all that happened was the start relay buzzed. I checked the fuses underpass and by the battery and none were blown. The relays checked out fine as did the ignorant switch. I have no power anywhere but at the starter. Nothing else. Also there is no power going to the 30amp starter fuse in the cab fuse box, any help would be greatly appreciated!
