I agree with Randall. Tape up and isolate the green wire for now. It doesn't look "factory" and could introduce problems depending on what a previous owner used it for.
When I look at your second picture the meter reading looks like 71.4 Ohms, not 1.4. Am I seeing that right? In that picture the red meter lead doesn't appear to be touching anything.
As Randall said, go back and measure the coil operating voltage. I'll add one suggestion though. Remove the distributor cap and place a penny between the points. Then turn the key to the run position and measure between coil (+) and battery (-). If you measure 12V, there is no resistor in the circuit. If you measure 6 to 9V, the car has already got a resistance wire or ballast resistor. The penny between the points will make the circuit complete so your voltage reading will be accurate. Don't forget to remove the penny when you are done.
Let us know what you measure.
