6 volt would have been + ground originally.

In reality, it doesn't matter which way you wire it up. The "electronics" on a stock Super C are not fussy about ground. All you need to do is polarize the generator once everything is connected, and start the tractor. If you can verify that the generator is charging properly, but the needle moves to the left, then swap the two wires on the ammeter.
