Distributor: Testing and Inspection

IIA 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).
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.

Primary coil resistance:
Cold: 1.11 - 1.75 0hms
Hot: 1.41 - 2.05 0hms

- 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 - 15.7 k Ohms
Hot: 11.4- 18.4 k0hms

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

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.

COLD:
G(+) - G(-): 185 - 275 0hms
NE(+) - NE(-): 370 - 550 0hms
HOT:
G(+) - G(-): 240 - 325 0hms
NE(+) - NE(-): 475 - 650 0hms

- 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 IIA CONNECTORS.
