Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ignition Coil Resistance (Protege)
Ignition coil is integrated into distributor. Disconnect distributor 7-pin connector. Remove distributor cap. Using an ohmmeter, measure secondary resistance between terminal "G" and coil tower. See Fig 5. If resistance is not as specified, replace distributor. See IGNITION COIL RESISTANCE table.
