- Disconnect 4-pin connector from ignition coil and ignitor assembly. Using an ohmmeter, check primary resistance between terminals No. 1 and 2 for one coil. Check primary resistance between terminals No. 2 and 4 for remaining coil. Resistance should be as specified. See Fig 1. IGNITION COIL RESISTANCE - OHMS @ 68Β°F (20Β°C)Β table. If resistance is not as specified for each coil, replace ignition coil assembly.
- To test secondary resistance, connect ohmmeter between ignition coil secondary terminals No. 1 and 2, and terminals No. 3 and 4. See Fig 2. If resistance of each coil is not as specified, replace ignition coil assembly. See IGNITION COIL RESISTANCE - OHMS @ 68Β°F (20Β°C)Β table.
