For most it is usually a matter of grabbing an old alternator off a parts vehicle from out back, most are negative ground so the tractor gets converted to work with what you have on hand.
With he improved availability of 12 positive ground alternators if you are going to be buying a new alternator I guess you could buy a positive ground one and minimize the things you would have to change over.
