Ignition Coil Test

  1. With ignition off, check secondary resistance between coil "DEC" (negative) terminal and coil tower. See Figure and Figure. Resistance should be between 7000-13, 000 ohms.
  2. Check primary resistance between "BAT" (positive) and "DEC" (negative) coil terminals. Resistance should be 1.13-1.23 ohms (.71-.77 ohms Dura-Spark I ignition system). If resistance is not within specifications, replace ignition coil.
