I have a JD-B that after starting it for the last three years without problems, all of sudden the positive 12 volt battery post started turning black causing the tractor not to start until I remove the cable and polish up the post. After this, for a couple of weeks, the tractor starts good, and then all of a sudden it won't start, and I have to repeat the process and clean the posts again for it to start.
