Check for voltage at coil neg terminal, which will indicate if ballast resistor and ignition which are a closed circuit. If the coil has voltage at negative terminal, then check for voltage at positive terminal and if you do turn motor over until no voltage. If voltage still exists on positive terminal, then take look at the points. Turn off the ignition switch and connect ohmmeter to positive coil terminal and turning motor over the ohmmeter should alternately show open circuit and closed circuit - zero resistance. Also, check the capacitor with the capacitance function of your meter. Is the capacitor grounded?
