run Farmall 6V w/a 12 battery??

John, Thanks for the info.
So until I do a full 12V conversion, I can just replace the coil with a 12V one (and keep the battery charged independantly).

Its cheaper to buy an add on external voltage dropping (12 to 6) ballast resistor (wired in series with coil ahead of it after the switch) then a full 12 volt coil though. They are available at like Rural King or Tractor Supply or Central Tractor or NAPA and usualy from 1.5 to 1.85 ohms around 30 watts.

The rest of the 12 Volt conversion aint all that expensive either cuz all you need is the genny changed to 12 volts or else try n cheat it by using a 12 volt VR (if its a VR system) or a 12 volt Cutout Relay and a correct light switch (it regulates the gennys field current).

True, a 6 volt gen wont keep her charged. I have used 6 volt gennys to charge a 12 volt battery by simply changing the 3 or 4 terminal Voltage Regulator (if it has one versus only a 2 wire Cutout Relay) to a 12 volt BUT AM NOT SAYING thats the correct or engineering proper way to do it, only that it worked. Its best to have a good genny shop convert it to 12 volts and use a 12 volt 3 or 4 terminal VR or one can still use the old 2 wire cutout relay system by replacing the Cutout Relay with a 12 volt unit.

Any working lights need, of course, to be changed to 12 volts.

The starter will work on 12 volts, although it may possibly be a tad rough on starter drives or flywheel teeth due the the higher kick in torque.
