I recntly put a new (6 volt) battery in my 9N and a couple of days later, the generator didn't seem to be charging as it should. I bought home tools etc. from work to clean up and repair connections but still had the same problem. It would only charge about 6.2- 6.6 volts at full RPM. Mind you now ,this unit's been on the tractor a good 25 years with no troubles at all so it doesn't owe me a dime! I took the commutator/brush end off and one of the brushes wasn't quite touching the armature as much as it should. I tweaked the spring and adjusted the holder to to make it hit better on the armature and lo and behold ! it charges at 7.5- 7.8 volts now! I hope this isn't too high because I can adjust the voltage with the brush holder in the end plate. I'd never had it apart before Saturday but it reminds me of the old Delco's I used to rebuild back in thr late 70's for Mack trucks. Also ,my Dad had wired the regulator to use nothing but the cutout in the regulator. It charges so good now I'm considering putting on new headlighs and caution lights on the rear since people out here drive so fast on these back roads. Thanks for listening and if I can help anyone else I'll try.

If you have a 1-wire genny then all you can use is the cutout part of a voltage regulator.
You can adjust the genny with those brush holders. And they need to be set properly so you have a strong charging system. But that"s not the end of it. The set points are battery voltage and coil voltage; that"s the bottom line. You don"t want to damage batteries with an overcharge and you don"t want to put too much volts on the coil because they melt.
Minimum brush length is 0.350". Max out is 11.5amps at 925rpm. That is less than half-throttle. Volts would be 6.5. The cutout should be adjusted to a closing voltage 6.5 to 7.25 and the opening volts 1/2 to 1-1/2 volts less than the closing voltage or 6amps max reverse current at 6 volts minimum. It"s your tractor and you can make it do whatever you can get away with but be sure to check the volts at the coil (3.5v is all you can stand) and don"t boil the battery.
