Insulation Resistance

Fig. 12 Checking ignition coil insulation resistance:

1. Check resistance by placing suitable ohmmeter leads as shown.
2. Resistance should be within specifications shown in IGNITION SPECIFICATION CHART.
3. Inspect coil for cracks, damaged or burned terminals and leakage.
4. If coil resistance is not within specifications, or if coil is damaged, coil should be replaced.
