Ignition Coil Resistance Test
- Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between positive and negative terminals of coil. See IGNITION COIL RESISTANCE table.
- Check secondary resistance between center tower and negative terminal of coil. See IGNITION COIL RESISTANCE table. Replace coil if readings are not within specification.
IGNITION COIL RESISTANCE
| Application | Primary | Secondary |
|---|---|---|
| Diamond Coil | .97-1.18 | 11,300-15,300 |
| Toyodenso Coil | .95-1.20 | 11,300-13,300 |
