Ignition Coil: Testing and Inspection

PROCEDURE

NOTE: "Cold" and "Hot" in the following sentences express the temperature of the coils themselves. Cold is from -10°C (14°F) to 50°C (122°F) and Hot is from 50°C (122°F) to 100°C (212°F).




1. Disconnect Negative (-) Terminal Cable From Battery.

CAUTION: Work must be started after 90 seconds from the time the ignition switch is turned to the "LOCK" position and the negative (-) terminal cable is disconnected from the battery.





2. Remove V-bank Cover; Using a 5 mm hexagon wrench, remove the 2 cap nuts and V-bank cover.





3. Disconnect Ignition Coil Connectors.





4. Inspect Primary Coil Resistance Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.

Primary coil resistance (Cold): 0.54 - 0.84 Ohms
Primary coil resistance (Hot): 0.68 - 0.98 Ohms

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

5. Reconnect Ignition Coil Connectors.





6. Reinstall V-bank Cover; Using a 5 mm hexagon wrench, install the V-bank cover with the 2 cap nuts.

NOTE: when repositioning the V-bank cover, push on the cover until a "click" is felt.

7. Reconnect Negative (-) Terminal Cable To Battery
