Distributor: Testing and Inspection
IMPORTANT: Discoloration of the cap and some whitish build up around the cap terminals is normal. Yellowing of the rotor cap, darkening and some
carbon build up under the rotor segment is normal Replacement of the cap and the rotor is not necessary unless there is a driveability concern.
1. Inspect the cap for cracks, tiny holes or carbon tracks between the cap terminal traces. Diagnose the carbon tracks using the following procedure:
1. Remove the cap. Place 1 base ohmmeter lead on a cap terminal.
2. Use the other lead in order to probe all other terminals and the center carbon ball.
3. Move the base lead to the next terminal. Probe all other leads.
4. Continue this procedure until you test all the secondary terminals.
5. If there are any non-infinite readings, replace the cap.
2. Inspect the cap for over excessive build-up of corrosion on the terminals. Scrape clean the terminals. Replace the cap if the corrosion is excessive.
Some buildup is normal.
3. Inspect the rotor segment for excessive wear. Replace the rotor if excessive looseness in the rotor segment is present.

1. Insert the shaft in the housing.
2. If the shaft wobbles, replace the housing assembly.
5. Inspect the housing for cracks or damage. Refer to Engine Controls for ignition system diagnosis.
