I'm not sure I understand all that you have posted.

A vehicle or tractor should be insulated by the tires from the earth so there should be no shock when you touch it whether negative or positive ground.

"The whole tractor was grounded. (Just enough to make you junp back if you touched it.)" Were you getting shocked when you touched the tractor? If so, there surely is a pinched wire or bare wire that is at fault for this.

Did you buy a 12 volt coil, or a 6 volt replacement coil? Perhaps you don't need the resistor.

Are you still running the negative terminal of the battery to the block or other casting? Is the positive terminal of the battery run to the starter, then a wire to the ignition switch, which has a wire going to the coil (via resistor) or direct?

Was the old coil grounded to the frame with the holding strap, i.e. was it free of paint under the strap? I don't even know if it should be, but I would make sure the new one and old one were alike in this manner.

You can always do a temporary by-pass of the switch and run a wire direct from the battery to the resistor or coil, then try to start the tractor. This is strictly hot wired and is temporary and briefly only to see if this might make a difference.

I'm just tossing out ideas since I don't know how a Ford is wired, etc. With all you have done/replaced you should have an excellent spark.

I would suggest you work on getting a strong spark back. Can I assume that your battery is still well charged?
