Odd Part on Engine Bay Relay

[Robsey]

Hi All,

I have been going through one of my old van donor looms that I have had for ages.

Possibly from a now defunkt seller Water Wagons.
Not 100% sure as it was so long ago.
Should be from a 1987 DJ.

Anyway came across this retro fitted relay and a peculiar enclosed diode thingamibob.

As you can see, the markings look 'typed' on a paper sleeve taped in place.

One side says -
1724278. 9
The gap after the 8. is intentional.



And the other side says -
1, 0k



There is a diode symbol embossed on the body adjacent to the label.

Anyway - the obvious questions...
What the chuff is it?
And what would it be used for?.

The relay has an ignition live feed, [86]
Two linked earth wires, [85 & 87]
And this thing stuck off the other leg. [30]

Sadly no wire connected to the male end of the contraption so no wire colours to identify a potential function.

Whatever it is that is connected to the gizmo,..
With the ignition on, it is shorted to ground via the gizmo.

Google does not help at all, so...

Over to you chaps.

Something LPG system related perhaps?

1.0 K ohm? Is it a dimming relay?

[Robsey]

I cannot think what a one-way current flow 1k ohm resister would be used for.

But it is obviously a retro fit item with a fused relay, and those horrible hard plastic crimp covers.

All I can say is that it was definitely part of the wiring spaghetti in the engine bay.

On closer inspection,
The ground wire is hideously scotch-lok'd to the ground side of the number-plate illumination loom.



And the black wire that I thought was ignition live, is scotch-lok'd to the red/black wire in one of the 7-pin barrel connectors.
T7a/6
Linked to the starter circuit.



Very weird.

By the way, I didn't hack the number-plate wire, I think it came that way.

The red/black wire would be used by the DigiJet control units.
Idle Speed Stabilisation Unit, and the engine control unit.
