Distributor: Testing and Inspection

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. 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 ohm
Hot: 0.45 - 0.65 ohm

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





6. 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 K ohm
Hot: 11.4 - 18.1 K ohm

- 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 ohm
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
