CAR-IDENTIFICATION LATE SPRITE & MIDGET (1967-1979)

A model year does not necessarily coincide with the year in which the car was built. For example, it may be seen from the following chart that while a car built in January 1972 is indeed a 1972 model year car, another one built in August of that year is a 1973 model year car. There are several different reasons for this. One reason is that it is easier to bring in changes in a model's specification when production has been halted already for a holiday shut down. Another reason is that motor shows usually took place in the Autumn and Winter, displaying the following year's new or updated models. Detailed here are the Sprite and Midget model years relevant to our categories.

Cars built after the chassis numbers below were fitted with reversing lamps, which automatically operated when reverse gear was engaged. A plunger switch, in a threaded hole in the gearbox remote housing, sensed when the gear selector mechanism was in the reverse gear position. Owners wishing to fit reversing lights to cars not originally so fitted would be wise to check whether the gearbox remote housing in their car has the necessary tapped hole to accept the switch. If it has, the only major task is to site the reversing lamp(s). Those without the correct housing will either have to try to obtain one, or fit a manual switch and a warning lamp in the cockpit of the car (the warning lamp is a legal requirement in the UK for manually operated reversing lights). Wiring provisions will have to be made to connect the switch, power source and lamps. Before fitting reversing lamps (or any auxiliary lamp), local regulations should be consulted regarding positioning, quantities, power, warning lamp requirements, etc.

Two distinctly different designs of voltage control box were used on dynamo-fitted MG Midgets and Austin Healey Sprites. The chassis number of your vehicle will indicate which type should be fitted (as detailed above). If in doubt, count how many screws fix the unit to the car, study the method used to retain the cover over the electrical mechanism, or read the manufacturer’s information and terminal coding stamped on the unit. The earlier unit is the Lucas model RB106. It may be identified by its two screw attachment to the bulkhead, the spring wire clip securing the cover and its terminals, which are marked ‘A1’, ‘A’ ‘F’, ‘D’ and ‘E’. The later type is the Lucas model RB340. It is attached to the car with three screws, the cover is retained by two push-in snap headed fasteners and it bears the terminal identifications ‘E’, ‘D’, ‘WL’, ‘F’ and ‘B’. The two types of voltage control unit are not easily interchangeable. It is not correct to say that either unit will always bear the Lucas name and/or the model type number. This is due to reproductions from non original equipment manufacturers servicing the demands of the marketplace. The quality of such units should not be dismissed, because these alternative manufacturers often supply product to Lucas. Within the pages of the factory-produced workshop manual, details may be found for test and adjustment procedures relevant to each of the two types of control box. Such adjustments are to rectify problems that may have occurred during service. If components within the voltage control box are found to be damaged, it will probably be easier to replace the entire unit. However, simply cleaning the electrical contacts often cures a charging fault.
