problem with dual point no spark

Here's what this boils down to..........The points are simply a switch to ground. On these type dual point, they overlap. This means only ONE set has to be closed to obtain continuity, but BOTH must be open to open the circuit. So with a test light or ohmeter, "at some point" in the rotation, you should have continuity from the dist. wire to the case, and at some point you should have infinity. The only other thing in there is the condenser. If the condenser is badly enough shorted, you will not have spark, and if it's leaky, none, and if it's open, none. It must be a "good" condenser. In an emergency, you can use the radio cap (hooked to the coil +) for a test substitute. So if you have power and a known good coil, it has to work.

You can bypass the ballast resistor "for testing" by jumpering power right to the coil + Don't leave that sit there for long, as you can burn the points or even ruin the coil
