Hi. Latest on my woes! The white cable at the relay IS getting a regular supply of 10.3v every time I turn the ignition to crank. I think my early test must have been a mistake. Testing at the back of the ignition switch also gets 10.30v...

Hi. Yes, sorry. It's a 200tdi - forgot to mention!

Hi On startup, there is a lot of squeaking coming from the belt area. I can't tell if it's belts slipping. Is there a way of testing this. I'm also worried that it could be a timing belt about to fail? On startup the last couple of times...

Intermittent is how mine was for a while so I had the under bonnet lash up and then the jumper until I sorted it. Some other relay behind the main group would click when testing mine [1990 19j] No glow plug relay on pre Defender model diesels...

Ah, could be. I don't actually know where that is, and I don't yet know what the other relays under the fuses are..... Need to find that out..... Wiring diagram (which I THINK is right for my year) also says brake check relay???

Is the clickeing the glow plug relay? Or is yours under the bonnet Nothing else clicks near my fuse box(early glass fuse type)

Thanks for this. Totally clarifies what should be happening. Mine's slightly different in that the Brown/Red is white in my case. I think my relay has 5 terminals but the one in the middle doesn't seem to have a connecting cable.

Think mine had the relay as it was a V8 (1985)

Have to admit when we had the same issue I did none of that fault finding, I just bought a switch for the price of it. If I was having to strip it out to test it all I may aswell replace it anyway, it fixed the problem in our case. You may well...

Jumper's a good idea. I'll definitely make one up and keep it in the toolkit for emergencies. Yes, agree about the relay. Seems over the top.

Few questions.. Have you/could you disturbed the rear of the ignition barrel? >> Very possibly. I need to check that out. Unfortunately it means dismantling everything I've put back. :( But hey-ho... Starter relay. Just swap this for a...

Sounds like a good set of tests. I'll get on it asap. Thanks!

https://www.ebay.co.uk/itm/235127935875 Buy the right one as they are not all the same. If you are confident the white wire is at fault could you not energies the relay with 12v just to test it? Then run a replacement wire from the relevant...

I am no electrician but sounds like, from your description you should get a live, white, when you turn the ignition to crank position. This energies the relay, circuit made by the earth wire, and let's current flow to the starter. Warning: I...

Having been away for 10 days, I've got back to these issues. I think I've sorted the earth on the temp gauge but I'm still getting intermittent problems with starting. When I turn the key to start I intermittently (usually) get nothing. There...

12.2v is a good voltage, may be an issue with the relay, swap with one of the others to test. When I was having start on the key intermittent issues I had a stand by rig of a wire from a known 12v feed with a switch in it and a double spade to...

I take your point about the birds nest. I assumed the battery was flat. It was reading 12.2v which I assumed was low. After recharge, the landy started up fine. But then wouldn't restart after a 1 mile journey - battery still should have...

The lower dash is just about the only area I have not been into. I could do with re sealing the cabin air flap in there. As for looking at the loom itself you may well find there is nothing to see unless there has been a big melt down. I have...

Thanks. Yes, I think the earths are good. It's had a recent professional rebuild onto a new chassis. It was starting fine before I got my mits on the instrument panel. But I'll check through that..... Thanks. Yes, I did suspect a drain. I...

Have you got a good earth connection to the battery? And another good connection from the engine to the chassis? If this one is bad the electrikity will try and complete the circuit any other way it can, resulting in odd things happening.

Sounds to me like you have a short in the system some where that is draining the battery. Someone bypassed the main loom to the fog for a reason. An 86 could well have a relay for the starter under the fuses, my 1990 did. But now has a direct...

Thanks Anaconda. I should add that there was a brief short at one point when i was doing the work (at a time I had the battery connected) between the fog light live feed and another connector and some clicking came from the relay area below the...

Ignition switch maybe and dash instrument earth. Obviously it's something you have touched so check your work. Hard to know what previous owners have done during an engine conversion.

More head scratching going on with my Land Rover Defender 90, 1986 200TDi (Discovery engine). So I completed some work in the dash, getting the instrument illuminators to work correctly on the proper switch rather than being hardwired to the...

You can get the instrument panel out with the steering wheel and bezels on, well mine you can and also my son's. Should mention there is evidence to suggest both of ours have rubbed slightly at sometime in their life. Steering wheel isn't really...

Hi, thanks for the great advice. Yes, I tightened the lower screws on the upper shroud first, followed by the steering wheel end which could have distorted the top shroud towards the steering wheel. I'll start again as you advise. It seems to...

I feel for you and I had in the past also faced similar situation when replacing parts around the steering column. This made it worse if they were plastics have warped slightly over time. A suggestion on how to approach would be to start with...

Hi Defender 90, 1986. Just fitted a new instrument panel and put on the shroud around the steering column Is there a best order to put the screws in underneath the shroud. When I put the shroud together it is very tight against the dash and...

Just to confirm @Hicap phill above the interior/ dash light switch as standard gives dash lights one way and interior light the other way with both off in the middle.
