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 rotor is not necessary unless there is a drive ability concern.
1. Inspect the cap for cracks, tiny holes or carbon tracks between the cap terminal traces. If the in side of the cap contains moisture or a filmy residue, wipe clean with a cloth lightly dampened with alcohol and allow to dry thoroughly. If the residue is hardened and cannot be removed, replace the cap.
2. Inspect the cap for excessive build-up of corrosion on the terminals. Scrape clean the terminals or 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.
4. Inspect the shaft for shaft-to-bushing looseness.
5. If the shaft is loose inside the bushing, replace the distributor.
6. Inspect the housing for cracks or damage.
