Hi, newbie here, need a little help, I was passed down a JD A (1948) hasn't run for 3 yrs some one stole sediment bowl and fuel line, so I replaced those, got it running, shut off to add more fuel to drive it around. When I restarted it, I took off the seat when I was starting it, and noticed the post on battery were smoking when I engaged the starter. I filed and wire brushed the connections but still smoked on engagement. Thought my father in law told me it was converted to 12 volt system but not 100% sure of that. It did start when hooked up negative to ground. If can help me out, thank you.
