TD5 Indicator problem

My 1999 TD5 Indicators work when the ignition is on but not when I start the vehicle. Have checked all fuses,pulled and checked the fuse box, replaced the hazard switch . Changed the indicator stalk . Is it in the ignition system? Thanks.

have you checked the relays and header for water ingress

Thanks Mystery there has been some moisture ingress so I am getting a new fuse box. All relays etc seem fine and work when ignition is on just not when engine is running. Is it possible to open the fuse box to check internally.?

Are you sure it isn't a problem coming from the ignition switch?
Altho I agree it is a bit weird that in that case the engine keeps running. But then I don't know the wiring diags off by heart!

Check all the earths, and there are a lot of them, they can cause all kind of wierd problems. I had headlamps on - engine cuts out. Slightly loose earth by the battery.

Thanks everyone. I will put new fuse box in today. If still no good I will work on ignition switch. All earths seem ok. This is the last problem left in the restoration so fingers crossed. As we all know water ingress causes issues and small leak in new windscreen didn't help but sorted that. This project has taught me patience and perseverance. My other Disco,D1, at 360K has never missed a beat so you can be lucky.

as the screen leaked check headers for water and corrosion the head un plugs to check them but care is required when re-inserting

...and make sure there isn't a problem at your trailer plug if you have one.

Thanks mystery and Stanley steamer. Will try new fuse box first and then the headers and trailer plug.

New fuse box in ,no change, so now think it might be ignition issue ,headers seem fine and dry, and trailer plug ok. Will check all earths again but running out of ideas. Got a flashing crossed B on the dash and odometer flashing.

Was that on with the old fusebox too?

Yes same on old fuse box. I suspect old fuse box was ok

Yes it was, you have to replace the BCU, this needs programming with nanocom or similar or contact https://www.ebay.co.uk/itm/133115857675

Thanks sierrafery the nanocom is a bit difficult as I live remotely on an island nowhere near a dealer. That's why I have learned the hard way with Land Rovers to do my own fixes. Might have to get a BCU from the UK. Its a shame because everything else works fine and unlike other threads I have read connected to this issue, rear windows, immobiliser etc all work. Thanks again for your help everyone.
