Check the contacts, tracks and resistors ringed

That's a TD5 warning panel (with LEDs), the OP probably has the 'bulb' version which is totally different

same source for both

Great! So hopefully sort both at same time!

Yes I have the bulb version built into the removable lights pannel in the dash I think (mines a 1987 with disco 200 tdi)

yu are quite correct.. just checking Rave, it also says 1.5W bulb, not 5w as I stated.

Yes, I'll also take a guess that your diff lock light doesn't work either as that shares the same supply

yep thats never worked either

thanks mad hat man looks complicated lol.

not the bit you need to know (top rh corner)

38 is the warning light and a brown yellow wire goes back to the alternator via ignition light resistor by the looks of it.

it appears the problem is between ignition switch and warning lights. not after

37 is the oil warning light which is next to the alt light but cant see anything in common other than the board they plug in to? Shouldnt the other side of 37 be a switched positive and pressure switch switches an earth (like the reversing switch?)
As you can probably guess i'm also learning!!

If yu look @37 its a typo - with no supply. I reckon the power is supplied by the W wire, like the others.

Yep, white feeds most of them so my guess is to start on the PCB

pcb?

Isn't there a PCB on the back of the ignition warning light shroud that the bulbs push and turn in via a holder?

Probably a bit of poor printing but I think the left side of 37 should continue straight across until it intersects the next point which will be 37's supply.

true there are 2 supplies white for ignition live services and brown for battery live services ie lights

If its the warning light pack I think it is then the bulbs push in from the front once the front panel is removed. The complete warning light pack is connected to the vehicle loom by two ribbon connectors. Possibility that the connectors have become dislodged which would have the same effect
