The big factor is that you are now dealing with a 12 volt system which reduces current flow by half. Your automotive cables will work fine on a 12 volt system. As far as color goes - typically on a DC circuit red indicates a positive lead and black indicates a negative lead. In reality - the electrons don't care what color the insulation is. I don't rely on cable color to troubleshoot. I follow the wires.
If you can't fix it with a hammer, you've got an electrical problem.

Wow, it sure is.
Interesting topic, I was curious if using dielectric grease on the farmall electrical system has any benefit.. Thanks
Well, I'll weigh in for what it's worth. Merlin is due for a new main cable from the battery to the starter because the one that came with him is still with him and is UGLY. The thing is that it is actually a 4-Gauge cable. It is what has been on the tractor since before I got it, and it has had no problem turning the engine over. Now, I don't recommend that size cable on anyone else's tractor because it is undersized for the current draw, but if the system is in good shape, it will handle the current.
