Ignition Coil: Testing and Inspection

IGNITION COIL 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)
- Hot is from 50°C (122°F) to 100°C (212°F)




1. DISCONNECT NEGATIVE (-) TERMINAL CABLE FROM BATTERY.

CAUTION: Work must not be started for at least 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.
