Help...was 8 degrees today, needed to work on a large manure pile. Upon keying on the starter, the starter continued to crank even when the ignition key was removed. Boom was down, could not disconnect the battery. Cranking but not starting, key in my pocket the positive battery cable caught on fire and melted the battery post right off the battery. Lasted about a minute. I know I sound like a believer in the tooth fairy, but hoping there is some hope for me. For starters, embarrassed to admit I have no idea where any fuses are located. Right now everything is dead. Applied 12 volts to the remaining battery leads but everything is dead including the computer panel. In my heart I know I'm in deep do do. Any encouraging suggestions ?
