1966 cub question 12V neg grd OR 6 v pos GND ????

[chrisbz9]

Hello Folks

I have a 1966 cub full size. I am returning to original condition. When I got the tracter, it did not have a battery. From what I have read this year tracter is a 12V negative ground system. Can someone please verify that this tracter is indeed a 12V , neg ground??????

Thank You!!!!!

Cubs went to 12 volt systems in mid 1964. So yours should be 12 volt negative ground.

My '67 is 12V negative ground.

HOWEVER, my Cub operator's manual, printed in 1970, still lists 6V positive ground as a possibility. It also shows crank start and a magneto.

I wonder if these were REALLY options in 1970, or if they just didn't bother taking those pages out of the manual?
