I have a lawn machine 608 (Model # 13 ak 608 g 062), and I'm having problems getting the mower started. When I try to start it, I blow the fuse that is in the back of the mower immediately and the starter wont crank the engine. I know it is not the starter, as I have removed it and taken it to be tested. It is also not the battery, that was checked as well and all of the electrical items work fine. I checked the wiring, I did not see any obvious areas where the wires were cut or pinched, there was some corrosion on the wires but I cleaned that up and it still doesn't seem to work. Any other ideas of what could be my issue? Thanks for your help.
