Lucas-Aid

Not many people realise that Joseph Lucas developed the first anti theft device, a 50:50 chance that the car would start…

Being the proud owner of a car so equipped I could marvel at the intermittent wiper and the world famous panel light modes, dim, flicker and off.  Lets not forget the self dimming headlight too.

The rebuild of lady Marilyn is, in the truest sense of the word, a nut and bolt rebuild. I do not believe that there’s a single bolt that hasn’t been out over the last three and a half years. The exception to this was the harness. The mighty electrical system and its two, yes two, fuses had served the car well. It must have done as it hadn’t burned to a crisp when I made the mistake of using the window washers with the headlights on. In fact, the harness had stopped smoking at all, which meant either topping up the harness smoke reservoir, or changing it completely.

Jerry Preston-Ladd has developed a new harness for the Challenger E, this is the reason it originally went to him. This update is the story of that harness.

The old harness was stripped out of the car and any usable parts retained (such as the headlight relay) the rest of the junk was consigned to the bin.

There were some oddities with the wiring which I can’t blame on Lucas. The headlights for instance, these were “joined to” (read twisted around) the indicators. The front side lights were attached to nothing at all. The total rewire was a mandatory feature of the rebuild.

What was going though their mind? I know Lady Marilyn was used as a publicity car for a time and maybe this was a desired feature, but the execution was truly pants…

The biggest concentration of harness activity happens around the centre dash. This is where the gauges and switches are afterall and this is also where the fuse blocks were located. The brown power leads went in first. The dash is wired through an ammeter so everything goes through that first before shooting off to its various locations.

In this picture the finished heater controls can be seen. another lovely job and the proper look for the car. As a new heater had been fitted the levers now drive a microswitch which operates an electric water valve. A neater solution than the cable operated alternative.

 

The signal wires went next as most of the functions are relay operated to cut down on the switched load.

Connector blocks were added for the engine and gearbox (makes removal a doddle) and also for the bonnet – which needs to come off if you’re doing anything much more that peering under it.

Jerry also added a some antitheft devices to the harness. I’m not quite daft enough to detail them, but there are clever and add a degree of protection against Mr Scumbag Car-thief.

Once the wiring was in place, it could be extensively tested before being taped up for good.

There was one particularly joyous moment when Jerrry sent me a phote of the front lights. They were:-

  1. On
  2. With sidelights
  3. Controlled by a switch
  4. Not on fire.

I may have shed a tear at that point.

So, the wiring was complete, better than the original, fully fuse protected and installed with a quality that old Joseph could only dream of. Job done, happy days.
