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 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
