Ignition Coil Resistance
- Disconnect wiring from ignition coil so ignition coil is isolated from the system. Using ohmmeter, check primary resistance between ignition coil positive (+) and negative (-) terminals. See Fig 1-20.
- Check secondary resistance between ignition coil positive (+) terminal and high tension wire terminal (coil wire tower). See Fig 6-25. Replace ignition coil if resistance is not within specification. See IGNITION COIL RESISTANCE table.
