Testing it off of the tractor is not definitive due to no load, and no side thrust. Loose bearings and skid marks on the armature laminations are sure signs. A starter draw meter is not expensive,and is placed on the outside of a cable while cranking. It should be about 200 to 350 amps when it is 50 out. Jim
