ADLM said: (quoted from post at 18:33:18 07/10/09) So are these exact matches to the original generator as far as looks go? I mean, if somebody didnt know any different would it pass for original equipment? Also, it looked like the one at tractoralternator.com was a 6 volt alternator. Why is this preferable over a 6 volt generator?
The big advantage an alternator has over a generator is that the alternator produces the electrical power in the outer, stationary winding.
Both generators and alternators produce electrical power by passing a coiled wired through a magnetic field. In a generator the magnets (field coils and pole shoes) are mounted inside the case and the wire coil (armature) is attached to the shaft and rotates. All the power produced must pass through the brushes to get out of the generator. As the armature spins there is arching as the brushed leave one commutator segment and slide onto the next. The commutator must be segmented because the current produced in the armature is alternating current. The brushes are arranged to only allow current to be drawn off in one direction. This quickly becomes a limiting factor in how much current can be passed through the brushes.
Electrically the alternator works the same way as the generator but the magnets (rotor) are spinning and the wire coil (stator) is attached to the housing. Diodes are used to limit the current flow in one direction only. This means that the current passed through the brushes now is only used to change the strength of the magnetic field and not the output current. Also the brushes can ride on slip rings rather than commutator bars resulting in much less wear hence the reason for the much smaller brushes.

Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
