Generator Not Charging

I have a 1952 TO-30 I am restoring. I can’t get the generator to charge. It has a new voltage regulator, the generator has been rebuilt, and it has a new battery. I am following the wiring diagram that you have on the Ferguson web site. I have rechecked everything. Any suggestions?

Have you polarized the generator? If your tractor is equipped with a generator and voltage regulator, they must be polarized before starting the tractor. See

Make sure the base of the voltage regulator is grounded. You can check it with a text light or VOM meter. Check each wire in the wiring harness individually with a meter to make sure it is ok. Try a different ammeter. If the ammeter is not working properly the generator will not charge.
