TD5 Short circuit Dilema

Jason2 · Nov 27, 2014

Hi

My 2001 110 TD5 has just cut out on me so I looked at all the usual stuff and found that the main 30amp fuse under the seat was blowing !! Put a tester on it and have got a down to earth on brown & green wire where I think it goes through the bulk head.

Problem is that there is no give in the cables and i can't get to it !!

So the way I see it I either cut the bulk head rubber' in bit's to try and get to it or run another wire ! But I do want to investigate the cause of this!

Any thoughts ?

Well I'm stumped with this one.

Rubber gromet where loom goes through bulkhead looks sound so I don't see how it can be shorting there

Inside you can't see bugger all !

After pulling and pushing the loom it's not shorting anymore and starts up fine but don't want to drive it like that as it will move again and cut out whilst driving

(like it did yesterday !! )

Looking at the wiring diagram for a td5 defender, I am guessing the wire you are looking at is the 30 amp f5. This goes to 2 places, the main relay which is in the satellite fuel box behind gear lever, but also to the inertia switch under the bonnet. I would check around this switch first and jump it out if possible. Happy hunting!

Thanks Derek

I was hopeing it just went from the fuse under the seat to the main fuse box. It definatly comes back and powers the yellow solenoid for the fuel pump. No way I'm going to find where it's shorting so i will have to run another wire.

TD5s are rather prone to wiring loom faults, I've discovered. There are lots of discussions on the internet about how people have suffered bizarre intermittent electronic faults which have eventually turned out to be faults in the wiring rather than the components. The trouble is that because it's the wires rather than the components it is hard to trace with fault code readers. I think Land Rover must have acquired batch of wiring with brittle fragile insulation and copper wires that go brittle sometime in the 2000s. Some people find its the corrugated plastic conduit that wears through the insulation on the wires themselves.

Thanks for that Brown

I have just yanked on the loom where it goes through the bulkhead and it's worked fine ever since but am not happy with this solution but am at a wit's end to what else I can do

I cut a piece of plastic pipe that I wanted to push underneath the loom where it goes through the bulkhead but it won't go in !!
