quantumfoam Posted June 24, 2016 Share Posted June 24, 2016 I have recently purchased a Defender 90 300Tdi 1998 and the only warning lights that work are the engine oil and battery. All the others do not work even though the actual items work (e.g. indicators side lights, main lights etc. I have continuity checked the fuses in the engine bay and those inside the cabin (AMR5718) and all seem OK. I have also had the warning light module out and checked each of the bulbs and they all seem OK. My next step is to voltage check the wires in the two clip in wiring harnesses that attaché to the warning light module to see if when the ignition is turned on there is a voltage to each of the bulb placements especially the glow plug one as I expected that to light up then go out. Anyone have any bright ideas about something simple I am missing or have fixed a similar problem Quote Link to comment Share on other sites More sharing options...
western Posted June 24, 2016 Share Posted June 24, 2016 could be broken tracks on the printed circuit of the warning light pack. your existing one might have a LR part number printed on it somewhere. here's a new AEU2721 BUT I don't know if it'll fit your vehicle. looking further, it seems this is the only part number. http://www.brit-car.co.uk/product.php/233416/0/printed_circuit Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted June 24, 2016 Share Posted June 24, 2016 If you replace the light unit, if it is a proper 98 model, not a 97 reg'd in 98, be aware the warning lights were quite different from pre98 ones. Quote Link to comment Share on other sites More sharing options...
