That sounds right. The ballast resistor is bypassed while the engine is cranking, it comes into the circuit when the engine is running. When you get it running you'll find the the voltage to be around 6 volts or so. If you have another coil handy swap it in place of the one you have. The primary resistance on most coils is 1.5 ohms or less and is hard without good equipment and since you have confirmed the ballast resistor is good and you're getting no spark out of the plugs that only leaves two things that can be wrong 1. the wire from the coil to the center of the dizzy cap or 2. a bad coil.
