Range Rover Classic Engine Electrics - Ignition System
Distributor Identification
Early vehicles (1970 to June 1981) have Lucas points type (35D8) distributors. Electronic ignition was introduced in July 1981. From this time, an A-suffix after the engine number denotes points ignition, and a B-suffix, electronic ignition (carb engines only – all Efi are electronic ignition).
From 1986, all distributors are electronic – either the Lucas 35DM8, having a separate ignition amplifier mounted underneath the coil, or on later vehicles, the Lucas 35DLM8, which has an amplifier module mounted on the side of the distributor itself.
From 1992 (3.9 & 4.2 litre), distributors have either a 2-pin amplifier module on the body of the distributor, or a 3-pin. The later 3-pin can be used to replace the 2-pin when fitted in conjunction with the appropriate link lead, part no. STC1212. The later 3.9 & 4.2 engines have a remote amplifier again, mounted away from the distributor.
Points type distributors can be converted to electronic ignition with Lumenition kit RB7270.
