Ignition Coil Primary Resistance Check

  1. With ignition switch in "OFF" position, disconnect ignition coil connector. Connector ohmmeter leads to positive and negative terminals of ignition coil. Measure resistance.
  2. If resistance was 0.3-1.0 ohms, proceed to "IGNITION COIL SECONDARY RESISTANCE CHECK ". If resistance was less than 0.3 or greater than 1.0 ohms, replace ignition coil.
