I keep thinking about doing under the bonnet, did it make much of a difference do you think?

stop, that's not real input 😜

You can get an aftermarket one for about £55 and has done its job several times on my rocky coast farm. After a meeting with a hidden boulder it was banana shaped but had done its job protecting things further back.

First of all, a huge thank you to everyone for your help. I'm extremely touched !☺️ As for my place of residence... I juggle between Versailles ( 78 ) and Verneuil-sur-Avre ( 27 ). So I slipped under my D2 and there's indeed a little play in...

I have bought genuine from them before, I have a feeling that in general most aftermarket versions will probably be the same one regardless of price. All the same they might be just fine.

Should be a large locking washer similar to a wheel bearing lock washer. That nut doesn't look far enough on in the photo. Welcome to the forum.

I was thinking about getting an aftermarket one but presumed it would be made from tin foil.

That's what I asked you, I guess you could get the chassis acid dipped. If that's viable I would get that done. Depends on your weather conditions if it's worth getting it painted or galvanise it.

The red/white relay trigger wire stays non live and the corresponding earth is live? Maybe the relay is faulty, shorting out triggering itself, possible maybe?

Are you sure the starter is re-energising or is it just still running? Aren't some glow plug relays timed, as in they stay on for certain amount of time even if engine is running.?

It is an actual Land Rover part which isn't cheap for what it is. My son has one on his Ninety, I quite like the look of them but in reality are probably pretty useless.

Really, what about the rust inside the chassis, you can't galvanise rust. It will carry on rusting from the inside out.

Isolate the spotlight wiring for now and concentrate on finding your headlight problem first.

They're just yellow Britpart ones - nothing special. Standard height. The last lot did me for 12 years so they're clearly not too bad.

Which springs did you buy?

I've had a go at the rear suspension bushes and ball joint. I last did them in 2013, so they've been good for 12 years. I did a whole thread on this in the autumn of 2013 so I shan't repeat it here. Plus I forgot to take very many pictures...

Why don't you draw a picture of exactly what you have wired to where for better help? It's taken 2 pages for you to tell use that you have fitted a fuse and relay.

Sorry, I meant the company in the link might have one.

Leave it in some very hot water for a few minutes

https://injectionpumps.co.uk/product-category/spare-parts/bosch-spare-parts/ve-spares/ Might have one.

How can you galvanise a rusty chassis? Can you acid dip it first to remove all the rust on the inside?

They are as tight as hell, warm it up first.

I had to bleed my son Ninety with the wheels off the ground..

Maybe he has fitted some relays?

Welcome to Landyzone.

Interesting, mine pass and so do my son's on both his Ninety and D2.

Don't presume the new battery is any good, I had a Bosch one which failed within a week. If you have a flat battery, jump it and leave it running with the charge light on it will still be flat, well flatter, than when you started it.

Joints on the ends of the propshafts.
