Ignition Coil Resistance
- Disconnect negative battery cable. Remove cover located above ignition coils. Disconnect electrical connectors from ignition coils.
- Using ohmmeter, measure ignition coil primary resistance between positive (+) and negative (-) terminals of each ignition coil. These are the terminals that electrical connector was installed on.
- Replace ignition coil if primary resistance is not .54-.84 ohms at 14-122°F (-10-50°C) and .68-.98 ohms at 122-212°F (50-100°C). Ignition coil secondary resistance cannot be measured. Reinstall electrical connectors on ignition coils, cover and negative battery cable.
