Ignition Coil Primary Resistance Check

  1. Disconnect ignition coil connector. Connect ohmmeter leads to "BATT" and "TACH" terminals of ignition coil. Measure resistance, and reconnect ignition coil connector.
  2. If resistance is 0.8-1.6 ohms, coil is OK. Proceed to "Primary Circuit Continuity Check". If resistance is less than 0.8 or greater than 1.6 ohms, replace ignition coil.
