Positive or Negitive Ground?


[ View Follow Ups ] [ Post Followup ] [ Return to Forum ]

Does anyone know for sure if a 1947 Farmall A has a positive or a negitive ground. Because for at least 18 years this tractor has been used as a negitive ground tractor. If this is a positive ground tractor would this have damaged the engine or charging system? Since the starter would have been running in reverse could the engine even run back ward? Right now I am replacing the generator and regulator. But before I start the engine I need to know for sure if this is a negitive or positive ground tractor. So that I do not damage the new parts. I have scamatics on the wiring so that will not be a problem but the ground will be.

As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U ... [Read Article]
