Ignition Coil Test

  1. 1
    With the ignition switch OFF, remove the distributor cap.
  2. 2
    Remove the 2 screws to disconnect the BLK/YEL and WHT/BLU wires from the terminals A and B respectively.

  3. 3
    Using an ohmmeter, measure resistance between the terminals. Replace the coil if the resistance is not within specifications.
    NOTE: Resistance will vary with the coil temperature; specifications are at 20°C (70°F)

Primary Winding Resistance (between the A and B terminals)
0.3-0.5 ohmsohms
Secondary Winding Resistance (between the A and secondary winding terminals)
9,440-14,160 ohmsohms
