Distributor: Testing and Inspection

SPARK TEST:

WARNING:
- High voltage in the ignition device system can cause strong electrical shock.
- Avoid direct contact to the vehicle body during the following spark test.

1. Remove the spark plug.
2. Connect the spark plug to a high-tension lead.




3. Hold the high-tension lead with insulated pliers 5 - 10 mm (0.20-0.39 in) from a ground.
4. Crank the engine and verify that there is a strong blue spark.
- If not, replace the spark plug or high-tension lead as necessary.



INTEGRAL IGNITION COIL
Inspection:

Primary coil winding:
1. Disconnect the distributor 3-pin connector.




2. Measure the resistance between terminals A and B by using an ohmmeter.

Specification: 0.49 - 0.74 Ohms @ 20 °C (68 °F)

3. If not as specified, replace the distributor.

Secondary coil winding:
1. Disconnect the distributor 3-pin connector.
2. Remove the distributor cap.




3. Measure the resistance as shown in the figure by using an ohmmeter.

Specification: 20 - 31 k Ohms @ 20 °C (68 °F)

4. If not as specified, replace the distributor.
