Due to thieves stealing the batteries off my most useful tractor, I've been taking the bats off each evening and carrying them to my one lockable shop garage . Next morning carry bats to tractor and re-install. Tractor too big for the garage. One terminal is quite close to the fuel tank and I always wedge a piece of hard wood between the terminal and the tank. Well today while running the discbine I smelled smoke and looked down to see major flames. Shut down, flames spread fast all over the 48 years of dirt and grease. I finally smothered the fire with many handful of green hay, I mean many balls of green hay. One battery burnt bad, many wires charred, hands took a beating. 1970 Int 826 and by far the best of my 14 tractors and it has never started and ran as good as lately. Where do I start? All new wiring harness? Who sells such?
