The yare suppose to be positive ground, 6 volt. but if it has been converted to 12 volt, with an alternator, thats probably fried! Need to know these things to be sure.

see if it still has a generator on it or if it has an alternator. if its an alternator, its 12v. if it has a generator, check the tag, if the tag is black, its a 6v genny. if the tag is red its a 12v genny. way back when, the early 60's chevy 12v gennys were a direct replacement for the 6v i-h genny. they could be run either pos or neg ground. i have one m that is 12v pos ground, also a w-9 that is 12v pos ground.
Im sorry I should have explained the tractors in more detail
The ole H has a generator and a magnito on it
The ole M has a generator and a distribitor on it
All wires look like original items like I mentioned before they both will start and run I dont know if they are charging right or should I go back to a 6 volt and if so is it also a positive ground ? I would like to keep them as close to original as possible..
Thanks for all your answers
