Ignition Coil: Testing and Inspection

IGNITION COIL INSPECTION

INSPECT IGNITION COIL
(a) Remove the air cleaner hose.
(b) Disconnect the high-tension cords and ignition coil connectors from the ignition coils.





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

Primary coil resistance:
Cold: 0.67 - 1.05 Ohms
Hot: 0.85 - 1.23 Ohms

If the resistance is not as specified, replace the ignition coil.
(d) Remove the ignition coils.





(e) Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.

Secondary coil resistance:
Cold: 9.3 - 16.0 K ohms
Hot: 11.7 - 18.8 K ohms

If the resistance is not as specified, replace the ignition coil.
(f) Install the ignition coils.
(g) Connect the ignition coil connectors and high-tension cords.
(h) Install the air cleaner hose.
