In 1970, Case switched to 2 12's. 2/0 cable will give the best service. Battery cable is like water pipe, the bigger the cable, the more juice it will carry. Maybe ol'e Doug won't see this, but keep the Ether can away. [Reply]   [No Email]

I know what works for me.   [Reply]   [No Email]

It takes cranking speed to fire diesels. That why you can replace 2 6"s in a 930 with a 12 , 1000 amp and it will almost throw the motor out of the tractor. Just waiting till the day the 6"s in our 730 go bad. I knwo a 12 will pop it off much faster. Bob   [Reply]   [No Email]
