equeen there are some vehicles (I say vehicle because some autos (Chrysler) are positive ground) that use a positive ground. Whom ever is doing your generator should be able to tell you if it is a positive or negative ground. If you have a positive ground system in your tractor and you hook it up as a negative ground it will fry your generator. And possibly some other systems, i.e. starter, amp gauge it can even melt wires.

You posted some bum info that will confuse.reverse polarity will not fry your generator, ammeter,amp gauge.Starter turns the same way, pos or neg.1/2 the vehicles built in 1940 were positive ground.All 6V tractors Ive worked on were pos ground.Reversing polarity on an alternator will damage it.
