For several years I have been running The small Nippondenso Alternator on My D 14, CA and H 3 With no troubles.
Honda and Toyota cars from the early 80s till about mid 90s have these units They cost about 15-20 bucks at the junkyard.
It takes 3 wires to make them work it is best to get the connector that plugs into the back of the unit it is a simple hookup.
I prefer these to the Delco because they are much smaller,About the diameter of the Gen. They tuck up under the hood very nicely I Think a person could wrap a piece of tin around it and trim it up to look just like a generator.If money is not a problem many of the small import tractors have very small alternators on them,They could easily be made to look like a generator.

Jim, there are several ways to do this. fist, by changing to 12 volts, the starter will crank faster, the lights must be changed, and the coil will need a dropping resistor, or changed to a 12 volt coil. The advantages of 12 volt is normally faster cranking and standardization with other vehicles around the farm/home. You can install a 12 volt generator and voltage regulator off something like a 1960 chevy pickup if you wish it to look "kind of original" that is what i did on my "B". Another method, cheaper is to install a new alternator with an internal voltage regulator. The cheapest alternator around is the DELCO 10SI used by General Motors in 1975-1985. You can get a rebuild at Auto Zone for $35. There are also about a million of them in the junk yard. Any Chevy, Pontiac or Buick had them. The newer alternators by DELCO around 1990-1995 are much smaller and look kind of neat. I am considering trying to find one and "test" on an old tractor. Problem is the are much more expensive (maybe not at the junk yard). Also the newer alternators have serpintine belts and the pulley must be changed. Last of all you will problay get several posts that say keep the 6 volt positive ground system. Some like "original", some want function. Its your choice. 12 volt negative ground is the new "standard". IF you decide to go with alternator or 12 volt generator send a note and i will get you a wire diagram.
