1975 lwb ex mod Landrover

Jan 22, 2005 32 Replies

I've just bought my first Landrover. I have the strange army 6 position switch on an extra mounting in the centre of the dash. I think I've worked out that moving one position to the left turns the tail lights on, again to the left does tails and side lights and finally 3 positions to the left does the tails, sides and headlights. But one position to the right does tails (why if ti can be done towards the left?) second position towards the right does tails and sides (why?) and finally third position to the right turns on the little convoy light under the rear cross member and leaves the dash board lights on. There is a separate switch on the side of this console that seems to shut all the lights off including the dash lights (why when it could be done using the main switch? Faster if the enemy is spotted??). There is another switch on the original dash above the heater switch that shuts off the dashboard lights alone. There is yet another square flat black switch on the centre console that has a red light on it that says test; what does it do? On the original dash there is an orange light in the top left hand corner; again what does it do? Is the wiring code different on military Landrovers and if so where can I find out what it is (if at all) This Landrover is also equipped with an oil cooler. Were all MoD Landrovers fitted with an oil cooler or was it only for vehicles going to hot countries. Finally! Is it possible to find out any of its history using any serial numbers.



TIA



PS What thread are the steering lock stop bolts :)

Good move.

I used to have an ex-SAS Range Rover that had been retro-fitted with a similar switch. This was a security switch, with a tab over it which meant you couldn't switch it on or off accidentally, and it cut all the lights, including courtesy lights. I was told it was for "covert operations". It's fine to have all the lights and dash lights off when you're on an obbo, but if you open the door and the interior light comes on...... Not sure how this relates to a Lightweight, mind.

Join EMLRA, and they will do a search for you for a couple of quid. Membership worth it for that alone.

Tests the bulb in the switch!

If the buld lights on it's own, it's because the balance of the hydraulic fluid has gone (a cylinder or pipe failed) - so it's actually a brake warning light, and the switch part is to test the bulb.

Erm, military 6-position switches have six positions, not seven. There are three in one directon, for normal use: usually HS&T, S&T, T, Off is in the centre, and two positions in the other direction, Convoy, Convoy+Side. Under the convoy setting, the brake lights should become inoperable as well.

I have not heard of this, but usually switching to Convoy will extinguish most interior lights. Certainly with a Map light & interior light these go out when Convoy or Convoy+S is selected.

This is for the brakes. You have dual-line brakes, which have a failover valve in them. Should one of the circuits fail, the red light will come on. Some vehicles have a servo fail switch as well, so the light will come on when there is no servo brake assistance.

The test button is so that you can check that the red light does in fact work - a blown bulb will obviously never light up to tell you the brakes have failed.

No idea!

If the vehicle is 12v, then a lot of the wiring will be standard landrover colour codes, additional military wiring may be different.

24v FFR models can be very different, youy best bet is Ex-Military Landrover Association, who should be able to furnish you with the correct wiring diagrams.

Some were, some weren't.

Yes, contact Dunsfold, or join EMLRA

If you mean the long adjustbale one, it's the same as the other bolts that hold the swivel seals on. 1/4" UNF. It should but up against a little stub of metal bolted under one of the bolts that hold the swivel onto the axle

Infra-Red switch? My lightweight has one, which cuts eveyting except the headlights. Those would be fitted with infra-red filters, and the driver would wear special goggles which converted IR to visible light. I've occasionally seen them on sale as single goggles -- they need to be a matched pair.

On mine, the IR switch got re-wired at some point.

Its not a lightweight, Courtesy lights? None of them either :)

Thanks :)

I'm sorry; you are quite right. Your description fits exactly.

It does seem odd..

Thank you very much. Looks like I'll have to join the EMLRA :)

Thanks very much.

I believe the passenger/co-pilot would wear the IR and would direct the driver. Given the tunnel vision effect of IR goggles I would expect it to be impossible to drive with them on

Tricky and a pain int the arse, yes. Impossible, no.

Regards. Mark.(AKA, Mr.Nice.)

All FFR's had them (fitted for radio) which yoiurs will be if it is or was 24volt. Also some others such as those for 'ot climate.

And 2 hours later he did indeed do that online.Welcome Mark.

Its definitely 12v now. Any clues to tell if it was ever 24v?

Your vehicle data plate says it was 12v

Think that might have been standard on all series vehicles at some time?

Might be for when a trailer is added, it will flash once when you indicate so you know the trailer indicators are working. I forget what the colour was but know that feature exists.

Sorry, read lwb as lwt. I'm gettin' old.

Do I get commission? :-)

We'll all call you Captain Rich from now on. Will that do?
