Ignition Coil Primary Resistance Check
- Disconnect ignition coil connector. Connect ohmmeter leads to "BATT" and "TACH" terminals of ignition coil. Measure resistance, remove ohmmeter leads, and reconnect ignition coil connector.
- If resistance was 0.8-1.6 ohms, proceed to Module-to-Coil Wire Voltage Check. If resistance was less than 0.8 ohms or greater than 1.6 ohms replace ignition coil.
