Hi Steve - You've understand/describe perfectly how the BN charging system is supposed to work!

With that aside, there's several possibilities why the generator won't doesn't charge in the "low" setting: Light switch field resistor is bad (open); there's a problem in the light switch (doesn't ground thru the field resistor in the L position); the switch/mounting bracket is not grounded (fresh paint is insulating mating parts). Could also be the ammeter simply won't read the 2 - 3 amps going thru it in the low charge position (check across the battery with an accurate voltmeter - anything higher than 6.5 volts means the battery IS taking a charge).

However if you only run the tractor for short periods (i.e. not hours on end at full speed) the battery will be fine charging on high all the time. Or you can dispense with the manual control by replacing the cutout with a voltage regulator for a later model 6 volt Farmall. Not 100% original, but it will be better for the battery over the long haul.

Hope this helps, and save mid- to late-August 2005 bot bring your BN to the Churchville and Hamlin shows!!
