I bought a disconnect switch locally, the type with a big turn dial OFF/ON. They only had normal 12volt wire in the store. I am breaking the POSITIVE ground. Will it matter if I run the 12volt wire from the frame to the disconnect and then the good 6 volt wire from the disconnect to the battery?

Do ground wires carry current or is just the Negative wire from the battery to the starter the important one?

If the answer is the ground wires need to be 6 volt, do they make a 6 volt disconnect versus a 12 volt disconnect?
