Ignition system component check (Every 24 000 miles (40 000 km) or 2 years)

1 Before disturbing any part of the ignition system, disconnect the battery negative lead.

2 Identify and clearly mark all HT leads before disconnecting them from the spark plugs.

3 Refer to the appropriate Section in Chapter 5 and, where applicable, remove the distributor cap and rotor arm.

4 Clean the HT leads and distributor cap with a dry cloth. Scrape any corrosion or other deposits from the connectors and terminals.

Also clean the coil tower.

5 Renew the HT leads if they are cracked, burnt or otherwise damaged. If a multi-meter is available, measure the resistance of the leads. The desired value is given in the Specifications of Chapter 5.

6 Renew the distributor cap if it is cracked or badly burnt inside, or if there is evidence of tracking (black lines marking the path of HT leakage). If there is a carbon brush at the centre of the cap, make sure that it moves freely, and is not excessively worn (see illustration).

7 Clean the metal track of the rotor arm with fine abrasive paper. Renew the arm if it is cracked or badly burnt.

8 Refit the rotor arm and distributor cap.

9 Reconnect the HT leads to the spark plugs and coil.

10 Reconnect the battery and run the engine.
