I am not positive on your tractor but on a car this in an indication of either a bad regulator, alternator, or a short in the light wire itself. When the tractor is running you should see 14-15 volts at the battery. Less than that and it is not charging, more and the regulator is not controlling causing a risk of a boiled battery and is hard on the tractor electrical system.
