IGNITION COIL INSPECTION
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 IGNITION COIL CONNECTOR
2. DISCONNECT HIGH–TENSION CORD FROM IGNITION COIL
3. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the positive (+) and negative (–) terminals.
Primary coil resistance:
Cold:
0.36–0.55 Ω
Hot:
0.45–0.65 Ω
If the resistance is not as specified, replace the ignition coil.
4. INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the positive (+) and high–tension terminals.
Secondary coil resistance:
Cold:
9.0–15.4 kΩ
Hot:
11.4–18.1 kΩ
If the resistance is not as specified, replace the ignition coil.
5. RECONNECT HIGH–TENSION CORD TO IGNITION COIL
6. RECONNECT IGNITION COIL CONNECTOR

DISTRIBUTOR INSPECTION
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. REMOVE DISTRIBUTOR CAP WITHOUT DISCONNECTING HIGH–TENSION CORDS
2. REMOVE ROTOR
