Lucas inspection lamp socket/charging socket, part #301187, (under the facia on the left-hand side for Briggs).
An occasional dash of freeing oil on the moving parts of the instruments is prudent.
The clock routinely fails after long service, either due to the open nature of the workings collecting dust, dirt & debris, or the tape surrounding the coil drying and damaging the very thin wire or connections to it. The former is easily remedied by a clock repairer who will clean and oil the workings, the latter may sometimes be remedied by remaking solder joints to the coil, although it will naturally depend on where the wire has broken.
Do not confuse the above problems with an apparent stalling of the clock after powering. The clock must be started by pressing the lower button, twisting slightly, and releasing. It may take several attempts for this to work. Current will register high (approx. 20mA+) when stalled, medium when incorrectly engaged (approx. 8mA) and low when working correctly (less than 1mA).
Brass screws on ignition switch can become damaged or dirty, leading to electrical faults across the terminals.
To remove the instrument panel -
2 screws to left and right of panel on reverse side of facia. The Speedometer cable, temperature gauge and wiring must be disconnected to remove the panel completely.
Note that the bulb holders pull out of the rear of the panel (altho they are a tight fit) to allow bulbs to be changed without removing the instrument panel.
To remove the ignition switch -
1 screw each side on reverse side of facia.
The thermometer gauge is stamped on the reverse side with 'F' or 'K61', the latter being the gauge for the electric sender.
The matching temperature sender for the electric gauge is marked only with 'Smiths Industries Ltd'.
It is believed the temperature gauge of the Lanchester Leda (14) is interchangeable.
The inspection lamp socket may only have been fitted to the Briggs, however an example was found attached to an early Barker model, under the facia, exactly 1" from the right-hand side. The wiring did not appear original and this item may have been retrofitted.
Apparently, there is a VW speedometer cable which fits correctly at both ends but is a slightly different length. If any owner has more details, especially a part number, please contact us.
Despite the AC part numbers for bulbs, the majority have been found to be a 12V, 6W, 'Rival' bayonet type. Replaced bulbs often have values ranging from 2.2W (too dim) to 8W (too hot) - check your bulbs are 5 or 6W and replace if necessary.
The green printed patches on the glass of the instrument panel (only seen when the glass is removed from the panel) are believed to be intended for production, possibly for alignment purposes.
The ignition and oil lights can easily (and reversibly) be fitted with LEDs. The modification is not visible normally but saves you ever needing to change the bulbs again in your lifetime. The panel lighting (which was even criticized at the time) is greatly improved by replacing with approx. 16, 1.8mm or surface-mount white LEDs, mounted immediately behind the glass. When fitting LEDs, remember to fit also a limiting resistor and (optionally) a zener diode.
It is also possible to re-cover the panel with a laser-printed wood effect to match the original very closely, and to print the decal for the glass.
It is believed the instrument box (but not the glass) of the Lanchester Leda (14) is interchangeable.
All images are scanned from originals, wherever possible, at 100dpi (unless otherwise noted) and must be scaled when printed to preserve the original size (eg. scale up by 3 times for a 300dpi printer).
Note, however, that due to slight scaling inaccuracies during both the scanning and inevitably the printing, these images should be taken as an approximation for reference only.
In addition, drawings, measurements and notes of materials used are intended as a guide and aid to the restorer, and not necessarily a definitive, or even guaranteed correct, reference.
The instrument panel is separated from the facia by a rectangle of extruded rubber with a circular profile, a fragment of which is shown.
Although not mentioned in the parts catalog, this 0.03" thick, stiff, black gasket was found between the clock and instrument panel. Its purpose is unclear and it may not be original.
100dpi view through the rear of the instrument panel glass.
The green sections are printed on the front of the glass (their purpose is unknown and they are not visible when the glass is in the instrument panel), the white text with black drop-shadow is written to the reverse side.
None yet.
