Ignition Coil Resistance

Inspect coil for signs of arcing or leakage. Remove primary and secondary leads from ignition coil. Using ohmmeter, check primary resistance between (positive) and (negative) terminals of coil. See Fig 1 .
Check secondary resistance between (positive) terminal and coil tower. See V6 IGNITION COIL RESISTANCE table. Replace coil if readings are not within specifications.
