NOTICE: "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 DISTRIBUTOR CONNECTOR
2. REMOVE DISTRIBUTOR CAP AND ROTOR
3. REMOVE IGNITION COIL DUST COVER
4. INSPECT PRIMARY COIL RESISTANCE
-
Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.
Primary coil resistance:
Cold: 0.36-0.55 ohms
Hot: 0.45-0.65 ohms
-
If the resistance is not as specified, replace the ignition coil.
5. INSPECT SECONDARY COIL RESISTANCE
-
Using an ohmmeter, measure the resistance between positive (+) and high-tension terminals.
Secondary coil resistance:
Cold: 9.0-15.4 ohms.
Hot: 11.4-18.1 ohms.
