Attention: anyone reading these comments who is considering using an alternator on their "old" tractor - regardless of make. Many if not most of those old tractors were set up with positive ground. If you put an alternator on, it is very probably "not going to work," unless you change the old tractor grounding to a negative ground system. This is true no matter if you use an internally regulated alternator or if you must also purchase a voltage regulator. These original comments were only for those who already have converted or will convert and know if they need a voltage regulator or not. The alternators available are almost "exclusively" constructed for a neg ground. This is because by the time alternators were in common use, most auto systems mfgs were already using "neg ground." If these comments are totally greek to you, get someone who understands, so you won't fry something. And please, unless you are an experienced mechanic, don't try to incorporate a 6V-12V conversion along with other things like a complete tune-up, carb rebuild, etc. It will just get you confused and unable to track down a minor problem.
