Check to see if you're getting voltage to the upstream (ignition switch) side of the coil. You could have a loose connection, a bad switch, or a burned out ballast resistor. With the points closed and the ignition switch on, you should see about 9V at the coil + terminal, and battery voltage at the ignition switch side of the resistor. On the distributior side of the coil, points closed and ignition on, you should see very close to zero volts since the points are grounded. With the points open, you'll see battery voltage all the way to the side connector of the distributor. Dirty or burned points will show 2-3 volts or more on the downstream side of the coil and will give a weak spark of none at all. A shorted condenser will also kill the spark on an otherwise good ignition system
