Project Vivat! Recreating Television History


The first job was to replace the ignition and lighting switch. It was very intermittent in both of its main functions and had been attacked with the soldering iron several times in the past as can be seen from the picture above.

A “pattern part” was obtained but this proved to be wholly unsuitable and basically disintegrated on first use(!); an original “new old stock” replacement was eventually sourced and fitted after swapping the lock barrel over (as the replacement comes without a lock).

On the steering column there is the usual “stalk” switch for the indicators on the right side (although this also seems to have been “remoted” at some point).

Another “stalk” was fitted on the left side but had been broken off sometime during a “previous life”. We had worked out that it was something to do with the headlights but without a proper wiring diagram we were guessing somewhat.

Pressing the test meter into use showed that one wire was connected to the main beam headlights and the other to the dip beam headlights(!). This was a little odd as we already have one of the floor-mounted “press” switches for the main/dip beam switching.

We decided on a slight modification to allow it to function as a “headlight flash” as this is very useful and not easy to do with the existing lighting switch and floor switch.

The dip-beam wire was reconnected to the “permanent power” fuse (that runs the horn and cab lights) and a suitable “biased” switch was obtained. Unfortunately the housing cover was damaged along with the “stalk” but this was repaired with some “isopon”, sanded down and painted black.
