Ignition Coil Test
- Turn ignition off. Remove distributor cap. Remove screws retaining primary ignition leads. Remove primary leads from ignition coil. Using an ohmmeter, check resistance between primary terminals "A" and "B" on ignition coil. See Fig 1. Resistance should be .6-.8 ohm at 68°F (20°C).
- Check secondary resistance between terminal "A" and secondary terminal (coil tower). Resistance should be 12,800-19,200 ohms at 68°F (20°C). Replace coil if readings are not within specifications.
