Ignition Coil: Testing and Inspection
INSPECT IGNITION COIL
a. Remove the air cleaner hose.
b. Disconnect the high-tension cords from the ignition coils.
c. Disconnect the ignition coil connectors.
d. Inspect the primary coil resistance.
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.
e. Remove the ignition coils.
f.
Inspect the secondary coil resistance.
Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
Secondary coil resistance:
Cold 9.3 - 16.0 kOhms
Hot 11.7 - 18.8 kOhms.
If the resistance is not as specified, replace the ignition coil.
g. Reinstall the ignition coils.
h. Reconnect the ignition coil connectors and high-tension cords.
i.
