Cowman is correct. Coils do not have voltage they have internal resistance. If a coil has enough internal resistance to handle 12 volts with out getting hot then it can be considered a 12 volt coil. If the coil gets hot with 12 volts then a dropping or ballast resistor must be added. With the resistor added externally, normally the voltage at the coil will be somewhere around 6-7 volts. With the resistor added externally also allows for the starter relay to give full 12 volts to the coil when starting for a hotter spark.
Does this make any since, hope so?
The answer, will the JD coil work? Maybe, with a good understanding of you electrical system resistor or no resistor internal or external.
