How Do You Test The Ignition Coil In A 1968 Chevrolet?
The ignition coil is the heart of the 1968 Chevrolet’s ignition system. It is the ignition coil that provides the distributor with enough electrical energy to fire each of the engine’s spark plugs. An ignition coil is defective if it either produces no spark, or if the spark produced is weak. Testing the 1968 Chevy’s ignition coil requires checking the coil’s primary resistance and its secondary resistance with an ohmmeter. Attach the two alligator clips from a ohmmeter to the threaded rods located on top of the ignition coil. Some ohmmeters feature metal probes rather than alligator clips, in which case simply press each metal tip against the thread rods. Note the position of the ohmmeter’s needle on the bottom portion of the ohmmeter’s scale. The needle should read at approximately 1.0 ohms of resistance. If the value is above this reading, replace the coil. This test check’s the coil’s primary resistance. Connect the wire from the ohmmeter to the threaded pole on the top of the coil
