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: 0.49-0.73 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, by using an ohmmeter.

Specification: 20-31 k Ohms [20 °C {68 °F}]

4. If not as specified, replace the distributor.
