Right, I've had a look today, not sure what i'm really looking for with regards to the earthing point in fuse box, I'm gonna need a torch, will grab one at work tomorrow. Find that if I move the relay about the indicators start working again for a while. Was thinking it may be 2 seperate faults(the indicators and the compute/temp light)as the lights, brake lights etc all working fine. Is this a faulty relay or is it possible that its the contacts or something? Garage replaced the relay around 2 years ago for mot but the car hasn't moved since then.
Could be a faulty relay but I suspect a poor contact in the fusebox itself. Check the relay's connection in the fuse box, can you see them all clearly when the relay is removed, are they in good condition?.... When the relay is fitted, is it tight or does it move about easily? I would also suggest dropping the fusebox off it's hangers and check the back of it. Check it for condition and to see if it's got damp at all. Previous signs of damp will show itself as a green mouldy/crusty residue on the back connections. MK1's very often develop a windscreen leak just above the box, I still have one.. I have recently rewired the entire car and have corked the leak for now....
I will take some pictures for you tonight to help with some of the above where I can.
Before I do that you may want to look at my project thread as there are some pics there... links for that and my dub rides are in my sig below. not sure if anything is of any use to you....
The earthing point for all brown wired earths that are local to the fusebox should be connected to the location shown in the pic below.
If you see any earths not connected plug them in, also check that the ones that already are, are in good condition and make a tight contact.
