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).
"Hot" is from 50°C (122°F) to 100°C (212°F).

1. DISCONNECT DISTRIBUTOR CONNECTORS.
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 0hms
Hot: 0.45 - 0.65 0hms

- 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 k Ohms
Hot: 11.4 - 18.1 k Ohms

6. 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.

7. INSPECT PICK UP COIL RESISTANCE.



- Using an ohmmeter, measure the resistance between the terminals.

Pick Up Coil Resistance COLD:
G(+) - G(-): 185 - 275 0hms
NE(+) - NE(-): 370 - 550 0hms

Pick Up Coil Resistance HOT:
G(+) - G(-): 240 - 325 0hms
NE(+) - NE(-): 475 - 650 0hms

- If the resistance is not as specified, replace the distributor housing assembly.

8. REINSTALL IGNITION COIL DUST COVER.
9. REINSTALL ROTOR.
10. REINSTALL DISTRIBUTOR CAP.
11. RECONNECT DISTRIBUTOR CONNECTORS.
