On-Vehicle Inspection

DISTRIBUTOR INSPECTION

NOTICE: "Cold" and "Hot" in these sentences express the temperature of the coils themselves. "Cold" is from -10°C (14°F) to 50°C (104°F) and "Hot" is from 50°C (104°F) to 100°C (212°F).

1. DISCONNECT DISTRIBUTOR CONNECTOR
2. REMOVE DISTRIBUTOR CAP
3. REMOVE ROTOR
4 REMOVE IGNITION COIL DUST COVER

Ignition Coil





5. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the positive (+) and negative (-) terminals.

Primary coil resistance:
Cold: 0.36 - 0.55 0hm
Hot: 0.45 - 0.65 0hm

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.

Secondary coil resistance:
Cold: 9.0 - 15.4 K ohms
Hot: 11.4 - 18.1 K ohms

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

Distributor





7. INSPECT AIR GAP
Using a feeler gauge, measure the air gap between the signal rotor and pickup coil projection.

Air gap: 0.2 - 0.4 mm (0.008 - 0.016 in.)

If the air gap is not as specified, replace the distributor housing assembly.





8. INSPECT SIGNAL GENERATOR (PICKUP COIL) RESISTANCE
Using an ohmmeter. measure the resistance between the terminals.

Pickup coil resistance:
Cold: G + and G -:185 - 275 ohms
Hot: G + and G -:240 - 325 ohm

If the resistance is not as specified, replace the distributor housing assembly.
9. REINSTALL IGNITION COIL DUST COVER
10. REINSTALL ROTOR
11. REINSTALL DISTRIBUTOR CAP
12. RECONNECT DISTRIBUTOR CONNECTOR
