Ignition Coil Resistance

WARNING: This page is about a different car, the 1990 Saab 9000 and 1990 Saab 900. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition switch off. Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between tower and negative terminals of coil. Resistance should be as specified. See IGNITION COIL RESISTANCE table.

Check secondary resistance between positive and negative terminals of coil. See IGNITION COIL RESISTANCE table. Replace coil if readings are not within specification.
