40cpe, YEP, you seem to have it all correct now. The current draw in the coil primary circuit is most important ,but most guys just overlook doing those tests. When the resistor is cold and its ohms resistance is low that allows for a higher voltage at the coil for cold starting and when the resistor warms up (ohms increases) the voltage is reduced at the coil for hot starting and also allows a longer point life because of reduced current draw. Make sure you align your contacts perfectly parallel to each other so they have a long working life. You are good to go. Regards, Kevin.
