You should be able to find this information in your service and/or repair manual. The points must stay closed long enough to allow the coil's primary current to reach an acceptable value and open long enough to discharge and produce a spark. In engines of medium to high compression this kind of voltage is necessary to reliably arc across the gap on a spark plug and make enough fire to ignite the fuel/air mixture in a cylinder. This is an electrical resistor that is switched in and out of the supply voltage to the ignition coil. Generally, the secondary resistance should be between 6,000-8,000 ohms. The changing voltage in the primary winding serves as the 'movement' needed to induce a voltage in the secondary winding. The Drive and its partners may earn a commission if you purchase a product through one of our links. Secondly, I did my spark test, no spark at plugs, then off to the distributer. It's not very much because there are only a few windings in the primary, but it's enough to jump a small air-gap, such as the one between the just-opening points in the distributor. This is where practice and patience come in handy. Using a multimeter to test an ignition coil involves connecting the multimeter across the terminals of the coil that feed the primary and secondary windings of wire inside the coil. Now were here to impart that info onto you through our guide to testing ignition coils. To check whether or not it is caused by no spark, use the following method.
