HT leads, distributor cap and rotor arm - inspection and renewal
Ignition system - contact breaker type / HT leads, distributor cap and rotor arm - inspection and renewal

1 Clean all HT and LT leads by wiping along their length with a fuel-moistened cloth.

Inspect each lead for damage and renew if defective in any way.

2 Note the fitted position of each HT lead before disconnection. When removing a lead from a spark plug or the HT coil, pull the lead off by its rubber connector, not the lead itself.

3 The socket contacts on the distributor cap and HT coil should be cleaned if corroded. A smear of petroleum jelly (not grease) applied to the ferrule on the end of the HT lead will help to prevent corrosion.

4 Remove the distributor cap and rotor arm.

5 Examine the rotor arm and inside of the distributor cap . If the contacts are corroded or are excessively burnt, or if the carbon centre contact in the cap is worn away, renew the cap or rotor, as necessary. Check carefully for hairline cracks and signs of arcing.

6 Ensure that all HT leads are reinstalled in their correct firing order. Check that all leads are correctly routed and clear of moving or hot engine components. Ensure that all lead connections are secure and where applicable, protected.
