The tractor was born with positive ground system, but if properly configured will operate equally well on negative ground. Reversing connections on the ammeter is part of the positive to negative ground conversion.
"And as for burning points without a resistor if that would be a problem how would a 6 volt either John Deere or Farmall with battery ignition and no resisters ever in system run for years without ever burning points"
Because Ford front distributor coils were designed to operate with the resistor, A 1.5 ohm primary round can coil was designed to operate without a resistor on 6 volts or with a resistor approximately equal to the 1.5 ohms in a 12 volt system. A 3 ohm primary coil is designed to operate with no added resistor in a 12 volt system. It is all in the type of wire used to make the primary winding. Both 1.5 ohm and 3 ohm coils have one continuous wire as the primary winding, the 3 ohm coil does not have a separate resistor inside the can.
