Distributor: Testing and Inspection

NOTICE: Cold and Hot in the following sentences express the temperature of the coils themselves.
Cold is from 10°C (14°F) to 5O°C (122°F) and
Hot is from 50°C (122°F) to 1O0°C (212°F).


1. DISCONNECT DISTRIBUTOR CONNECTOR.
2. REMOVE DISTRIBUTOR CAP WITHOUT DISCONNECTING HIGH-TENSION CORDS.
3. REMOVE ROTOR.
4. INSPECT AIR GAPS.








- Using a thickness gauge, measure the gap between the signal rotor and the pickup coil projection.

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

- If the gap is not as specified, replace the distributor housing.
5. INSPECT SIGNAL GENERATOR (PICKUP COIL) RESISTANCE.





- Using an ohmmeter, check that the resistance of the pickup coil.

Pickup coil resistance:
Cold:
G1 and G(-): 185 - 275 Ohms
G2 and G(-): 185 - 275 Ohms
NE and G(-): 185 - 275 Ohms
Hot:
G1 and G(-): 240 - 325 Ohms
G2 and G(-): 240 - 325 Ohms
NE and G(-): 240 - 325 Ohms


- If the resistance is not as specified, replace the distributor housing.
6. REINSTALL ROTOR.
7. REINSTALL DISTRIBUTOR CAP.
8. RECONNECT DISTRIBUTOR CONNECTOR.
