Ignition Coil Resistance
- Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between positive and negative terminals of coil. Resistance should be as specified in IGNITION COIL RESISTANCE table. If not, replace ignition coil. See Fig 1 .
- Check secondary resistance between (positive) terminal and coil tower. See IGNITION COIL RESISTANCE table. If not within specifications, replace coil.
