Any starter with field coils will run the correct direction when fed from a pos or neg ground system. System polarity only becomes an issue with a permanent magnet field starter as used on small lawn mower/tractor type engines.
Glad someone posted that one wire Delco alternators converted to pos ground are avalible. One thing to consider is that if you install a pos ground alternator on a tractor that must run at a moments notice( driveway cleaner etc), do you have someone that stocks these specialty pos ground alternators or parts? if it fails. the pos ground conversion would need a special regulator,diode trio and rectifier unit. My point is that it might be better to convert the tractor to neg ground so standard,off the shelf parts can be used.
