Farmall 130 electric system

I'm new to this site and I appreciate what I have read here so far. I have a question related to my old farmall 130 that I am restoring. I assume that it is a negative ground electric system, but I just wanted to be sure. Thank You

If it's still the original 6 volt system, it would be positive ground.

Thank You DJ54 I was trying to use it Neg ground and my cable was getting hot. I plan on doing a complete tune up on it tomorrow. I hope I haven't ruined anything with the reverse polarity.
