Hey Bob M, and oher electrical gurus!

I got a little charging dilema though. The High charge switch setting gets about 12 Amps. The low setting gets none. I'm not much of an elctrician, but doesn't the high charge setting take the Field connection straight to ground, while the low charge setting puts the 2.8 Ohm resister between itself and ground? I followed the connections in the picture from my manual. Evverything works fine, except low charge. Truth is I don't mind it just the way it is, except I don't want to damage anything if it's not hooked up right.....any ides?

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!!

Wait til you see the BN. It's coming out really nice.

Anyway it won't hurt anything to run on low charge setting without the system charging - just remember to hang a charger on the battery every so often, especially after freezing weather sets in. OTOH unless you run the engine for long periods (like over 1 hour per start) it won't hurt to leave it charging on high, and will eliminate the need to separately charge the battery. ...Bob
