Ignition Coil: Testing and Inspection

INSPECT IGNITION COIL

(a) Disconnect the high-tension cords from the ignition coil.
(b) Disconnect the ignition coil connectors.





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

Secondary coil resistance:
Cold: 9.7 - 16.7 k ohms
Hot: 12.4 - 19.6 k ohms

If the resistance is not as specified, replace the ignition coil.
(d) Connect ignition coil connectors.
(e) Connect the high-tension cords from the ignition coils.
