Ignition Coil: Testing and Inspection
IGNITION COIL INSPECTION
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 IIA CONNECTORS.
2. REMOVE DISTRIBUTOR CAP.
3. REMOVE ROTOR.
4. REMOVE IGNITION COIL DUST COVER.
5. INSPECT PRIMARY COIL RESISTANCE.
-
Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.
Cold: 1.11 - 1.75 Ohms
Hot: 1.41 - 2.05 Ohms
-
If the resistance is not as specified, replace the ignition coil.
6. INSPECT SECONDARY COIL RESISTANCE.
-
Using an ohmmeter, measure the resistance between positive (+) and high-tension terminals.
Cold: 9.0 - 15.7 k Ohms
Hot: 11.4 - 18.4 k Ohms
-
If the resistance is not as specified, replace the ignition coil.
