Ignition Coil Secondary Resistance Check

  1. Disconnect ignition coil wire and ignition coil connector from coil. Connect ohmmeter leads to ignition coil "BATT" terminal and to high voltage terminal. Measure resistance and reconnect wire and connector.
  2. If resistance is 7, 700-10, 500 ohms, coil is OK, proceed to "MODULE-TO-COIL WIRE CHECK ". If resistance is less than 7, 700 or greater than 10, 500 ohms, replace ignition coil.
