I apologize if this question has been beat to death and I've missed the answer. I bought an early 50's TO-20 that had already been converted to 12 volt and has a 12 volt generator but the wires from the generator were dangling. A fellow is tuning it for me and said that it was missing the voltage regulator so I bought one that I am quite sure is a negative ground. He installed it but then said that I needed a positive ground regulator because the tractor was starting regardless of if he used positive or negative ground. That confuses me. So I need some clarity on the regulator with positive or negative ground. I guess I have the option of going to an alternator as well but I already have the voltage regulator and the generator so I really don't want to spend more and then just set these parts aside. Any help would be appreciated. Do I need a positive ground voltage regulator?
