If the change was recent, a person may find that the generator doesn't work properly. If it was polarized to negative ground then it will work.

There has been some contention about why they used positive ground. At this point in time, it doesn't really matter except for originality of design. The 6-volt conversion alternator that I have as a spare, has an internal jumper to allow for positive ground. A person has to keep this in mind if they change to negative ground and they want to use a conversion alternator. The alternators would need to be wired for whatever a person wanted to use as far as polarity. The generators can be polarized either way but reversing polarity on one may take a few attempts to get the proper magnetic gauss in the pole shoes.
