Ignition Coil: Testing and Inspection

INSPECT IGNITION COILS
a. Disconnect the high-tension cords from the ignition coils.
b. Disconnect the ignition coil connectors.




c. Using an ohmmeter, measure the primary coil resistance between the positive (+) and negative (-) terminals.
Primary coil resistance:




If the resistance is not specified, replace the ignition coil.




d. Using an ohmmeter, measure the secondary coil resistance between the positive (+) and high-tension terminal.
Secondary coil resistance:




If the resistance is not specified, replace the ignition coil.
e. Connect the ignition coil connectors.
f. Connect the high-tension cords to the ignition coils.
