If you're lucky, there'll be some vestigial printing, usually in white on the black paint covering the coil housing, to indicate whether it might be a coil meant to operate on 12 v without a resitor. Lacking that, it's pot luck.
Not exactly a harm -- it won't hurt anything, but the tractor just won't run right if at all -- to run a resistor in the line ahead of a coil designed to take a 12v input. The effect of the resistor is to reduce the 12v to 6v. I don't know enough about how a coil works to say that it would be a direct reduction, but . . . you get the picture.
Worth tryin' anyway. Can't hurt. Might work if you've got the 6v coil.
