If those voltage measurements are with the engine stopped and the points closed, you just found the problem. There should be less than one volt upstream of the points (usually a lot less) in that event. Measuring the voltage between the coil and the points with the engine running will show an average of "points open" (full charging system voltage) and "points closed" (zero volts). That's actually what a dwell meter is reading. Running full charging system voltage to a "resistor needed" coil will damage the coil and the points very quickly.
