Ignition Coil Resistance
- Disconnect wiring from ignition coil so ignition coil is isolated from system. Using ohmmeter, check primary resistance between ignition coil positive (+) and negative (-) terminals. See Fig 1, Fig 2 or Fig 3.
- Check secondary resistance between ignition coil positive (+) terminal and high tension wire terminal (coil wire tower). See Fig 4, Fig 5 or Fig 6. Replace ignition coil if resistance is not within specification. See appropriate IGNITION COIL RESISTANCE table.
