In my experience as an electrical engineer, most "electrical" faults are mechanical in nature!

Here is a poor picture of the vehicle in question. It was a DERA concept (later QinetiQ), known as the 6x6 Combat Support Vehicle. It had hybrid electric transmission, with six independant electric motors driving the wheels.
Known as the HEDV (Hybrid Electric Demonstrator Vehicle) IIRC. Six hub-mounted motors with a two-speed epicyclic gearbox in each hub, two 80kW generators and two 80kW Zebra batteries. There's a video here: http://www.qinetiq.com/home/defence/defence_solutions/landjo/HED/HED_demo_movie.html

I don't know anything about Land Rover electrics, but noting your comments about the problem temporarily fixing itself after you'd dismantled it I'd suggest a good look at the cables and connectors might be useful. If you can dismantle the connectors and look inside, so much the better.

I will try and get a list together of what he has got but I do not want to be in breach of HMVF terms and conditions so I would prefer contact via pm rather than the forum.

PM sent - possibly twice by accident as the site seems very sluggish tonight!

A shame we've already scrapped Fearless and Intrepid or the RAN could have had some ex-RN rust buckets instead!

I'd be interested to know what your boss has got in the way of 432 parts ...

Try this one it's simple enough to make on veroboard if you dont fancy making a pcb and can go into a small plastic box.

It's around on lots of electronic sites and seems to be from the IC manafacturers data sheet, so is a none copyright item for none comercial use.

That's the wrong way round - he wants to convert 6V to 12V!

On a point of order, the DVLA is not a private organisation, it's an Executive Agency of the Department of Transport. That means it is part of government, but it's set up to behave like a commercial organisation to ensure business-like behaviours. If that means making money then I think they're doing pretty well at it!

Is it just me, or has the site been on a "go slow" again for the last two days?

You're a glutton for punishment, Iain!

Hmm - so what do we reckon it is, then? Some sort of capacitor or tuned circuit across the battery terminals? Difficult to see how it could have any effect on a diesel!
Andy

What programme is that from, out of interest? And I know we shouldn't engage in politics, but scrapping the TSR2 at that stage in its development was possibly the most stupid thing I've seen a government do.

Apparently, it's not very clever to use the stuff in marine engines. Not sure why but it's what I have read.

I think you'll find that's because of the dreaded "diesel bug" - organic biomass that breeds in the fuel and forms black lumps and sludge which eventually block filters and pipes. What interests me is how long this will take to be a problem in the MV community, bearing in mind that the causes are fuel that has been subject to daily variations in temperature and stored for several months without use. Does that sound familiar? :undecided:

Usually known as Nyvin or Unipren? I don't think the original type is still manufactured, but there's some about (thexmod carry it). Unfortunately it's usually in enormous and therefore expensive reels!

whats happening with the fort now is it going to be open to the public like fort Nelson?
Not that I'm aware of. It seems to have turned into business units and a park and ride for Queen Alexandra's hospital.

I keep driving past this several times a week - does anyone know what sort of state it's in?
Andy

So, for those "eagle eyed" ones you will have noticed I called ours a TRV yet the in service pictures show it as a Fire Unit.
Yes, I did think something had gone missing!

What's the launcher gubbins on the FV432? Swingfire, perhaps?

Welcome aboard!

The Royal Marines band, fed up with being unappreciated by senior ranks, decided to demonstrate their applicability to modern non-lethal warfare ...

I watched "Pentagon Wars" last night on DVD. The opening titles are set over film of numbers of tanks doing things they shouldn't, with ensuing interesting results!
Andy

Some bits of that look very similar to the UK facilities at Hurn and Longcross. No indoor swimming pools, though!
Andy

Yeah there was a misconfiguration in their server, fixed now (after nagging and nagging).
Thanks Joris!

Update and a question on comms set up on FV434

As Chris says, you don't need a radio at all, just an IB2 or 3 and assorted CB2 or 3s. I'm using an IB3 and four CB2s in my 432, one for driver, one for commander and two in the crew compartment. All the internal cabling and brackets were there already. Here's a link for all you need to know: http://ferret-afv.org/manuals/clansman_wiring_harness_and_control_boxes_description.pdf
