Hello folks. New to this site hoping on answers and tips. I have a Ford 8n tractor that has a 226 industrial motor in it. I'm not sure what the difference between industrial and regular is. It's 6v neg ground. "
That should be 6 volt positive ground. If you are new to generators on auto engines,you need to buy a Motors Manual to cover 1948 to 1951 Ford cars or trucks.
One of the forgotten gems of information you will learn about is polarizing generators/voltage regulators.
If you hook up a system set up for positive ground with a negative ground,it will start and run normally,but the amp gauge will show a discharge,and all the other electrical gauges will read backwards. If this happens with you,you need to swap the battery cables to positive ground. You may or may not have to repolarize the generator/regulator. I can't remember now.
