When it got to the point of replacing the generator and battery, we switched it over to 12 volt neg ground. I got used to tapping the voltage regulator with my foot to get it to charge. Our 300 was 6 volt positive ground and was always hard to start and when it did run, it would not charge half the time.

If it charges when grounded, then you know the generator is OK and the regulator is bad. Take a jumper wire and ground the 'F' terminal on either the generator or voltage regulator.

The starter can 'take it' if you don't crank on it too long.Īt first I was thinking that the starter would try to turn the engine over backwards but this is not the case since the magnetic field in the starter gets reversed so everything works OK.

The original starter will work fine and spin the trator over much more quickly. The 12V battery is installed with the cables reversed compared to the original layout. The lights (if they still work ) would need to be switched to 12V bulbs.

When you switch over to 12v, the system then becomes a negative ground system. I changed it to 12V which is the way to go if you really want to keep using these tractors. My experience is limited too but my 'H' was a 6 volt positive ground.

Ammeter never gets to the + side, although it shows less of a discharge when he speeds up the motor. It is 6 volt, he claimed positive ground. Neighbor has a Farmall M that doesn't appear to be charging the battery.
