Indicators both on
Hi all,
Not sure if anyone can help me, as id like the 90 to be up and running after all this is over so I can drive it legally in the summer. Currently whenever I turn an indicator on the other side also starts indicating however slightly dipped. I have checked for the obvious cross wire etc. But can’t find anything that would indicate a reason. They were all working perfectly before I left the car for a couple months during the winter. Nothing seems to have changed, but if anyone has any idea do let me know. Only thing I can think of is that I’ve updated the side indicators to LEDs, but I wouldn’t see how that would be a problem.
TIA

Do you have a single indicator direction lamp on your warning panel rather than one for each direction?
If you do then the circuit relies on the filament in the indicator lamps to provide a ground.

LEDs (diodes) work in one direction so no longer provide the ground

The side repeaters (filaments) were probably still doing this, now you have LEDs all round there isn't a sufficient ground anymore.

There is a fix for this

You could put both your side repeaters back to filament lamps to prove this is the issue before spending the cash.

I'd say the same. I had a similar issue with my 110, same fix but I made the earth path myself Thumbs Up 2002 90 Td5 Station Wagon

As a quick check, disconnect the warning light panel to remove the indicator warning light bulb from the circuits Smile  1988 90 Td5 NAS soft top

Perfect thank you all. Is there a quick fix, just to add a ground or connect to a ground to fix the issue? I’m not the best with wiring so will need a simple break down Laughing

The easy fix is to buy the part, but not the cheapest. (pounds)
The alternative is the two diodes and small wire (pence) but you need a little electric know how

I don’t really want to spend £35 on earthing them, so is the diode way simple enough to do or will I need a bit more expertise?
Cheers all

You would only need the one lamp kit, not two. It's a replacement warning panel light.

The fix that dorsetsmith gave above requires doing this:

Cut Green/White and Green/Red indicator supplies to the warning light connector (leaving enough wire on the connector to work with)

Connect the Green/Red tail from the white connector to a ground (nut on the back of the gauges is good)

Solder the anode of two diodes to each of the Green/White and Green/Red coming from the bulkhead loom. Join the cathodes together, then connect to the Green/White tail on the white connector.

This combines the two indicator warning light feeds for a single lamp without the issue of back-powering the opposite side.  1988 90 Td5 NAS soft top

@BarrowG check your Flasher relay - I had exactly the same issue with both indicators being on and the relay was damp inside - visual condensation. I took it off, dried it out and sprayed with WD40 then re-sealed it.

This cured the issue and cost nothing 2017 Range Rover L405 Vogue SE V8 Diesel #16

Thanks very much Martin doesn’t seem too hard at all.

Cheers I will check this first. Where will I find the flasher relay? I do have a spare that came with my new wipacs when the others broke so could just swap them out

Hi all so I’ve just had a look and tried the different tests. I disconnect the white clip shown above and same problem happened so that could mean it isn’t the ground? I also read up else where that it could be the hazards causing a problem.
To follow up on what @Martin said about cutting wires and diodes I can’t seem to see a white/green or a green/red wire. Am I being stupid and looking in the wrong place?
Cheers

The indicator warning light has also now stopped working before taking off the white clip?

You’ll find them on the other flat white plug.
