What should resistance reading be on Ford ignition coil?
Keep the other lead on the positive post of the coil. Note the resistance reading on the ohmmeter. Your coil should have a reading of between 6,000 and 15,000 ohms for your Ford. Replace the coil with a new one if the readings are outside either of these ranges, as that would indicate a defective coil.
