Hi guys!
I have a disco 1,200tdi,from few days i have no wipers,heater blower,electric winfows/mirrors....anyi ideas where to start?

regards
Tibi

It’s not unknown that when multi circuits fail with a 200 series disco that there’s an issue with the fusible links (blown due to corrosion) they are located behind the battery and rapped in the fabric of the wiring loom that runs along the inner wing, there will be a small bulge in the loom where the positioned.

I would think that your vehicles links would have been replaced by now, but may not have been updated possibly by the fitment of a 300 series engine bay fuse box, although there was an aftermarket fusible loom produced for the early RR which also was known to suffer the same issue I believe.

Other than that check earth connections which may be in the front footwells like the 300s.

thank you much,i will check the connections

Here you go https://www.landyzone.co.uk/land-rover/pre-1993-fusible-links-problems.92317/ see the bulletin linked in post #3

where can i find this fusible link exactly?its a LHD disco,pre 93 200 tdi

It's clearely described in that technical bulletin at PROCEDURE - points 2; 3

My 1990 200tdi doesn’t have a fusible link, the main supply bolts straight through the bulkhead,
Something I am going to sort out in the near future with a 80 amp inline fuse near the battery,

It did when it left the factory and several of them.

My 1990 workshop wiring manual doesn’t show one and I have followed the loom back to the bulkhead were a isolated stud takes the feed through to the interior, I guarantee there isn’t one on my Disco that I’ve had from new,
I know on the later Discovery they fitted several inline fuse links in the main wiring harness because the earlier discovery caught light if they had a wiring short circuit,
I wouldn’t go to the trouble of fitting my own fuse link if one was already present,

So according to that diagram the whole starter circuit is not protected at all ? ...what's that ''terminal post" ST2 ?

ST2 is the insulated stud that take the main battery power through the bulkhead onto the fuse box,

As usual and for a long while from the original RR to the 200 series and very early Disco there is a question of the fusible links of those vehicles.
It appears from LRs workshop documents for the D1 the links were introduced with the (J) VIN in 1994 (change over year) so that makes it the 300 series which we all know the links are housed along the normal fuses in the engine bay fuse box.
As I know the early RRs had the links, mine did, I must have asked but never need to go there, I could just make them out as a lump in the loom of my RR behind the battery.
So the links being concealed as they were perhaps LR didn’t intend them to be a serviceable item hence they aren’t mentioned in the workshop manuals until the disco had an engine bay fuse box, l haven't check in my RR manual but I will have a look later.

In my experience of cars I’ve owned, fusible links weren’t around when my vehicles had only one fuse box, and that was always mounted within the engine bay or boot and fitted few feet from the battery.

I think maybe something is in there and well concealed as you say cos searching for the first p/n of the battery cable came up with
PRC8566 - CABLE-BATTERY POSITIVE 'CLASSIC PART' [ to - (V)JA034313 ] (so up to '92) which was superseded by this https://www.brit-car.co.uk/product....attery_to_starter_motor___discovery_1___ka_on so the same part... the gist is it's price compared with the latest versions which were definitely without fusible link https://www.brit-car.co.uk/product.php/107302/5497/cable___battery_to_starter_motor ...so why that big price if the early type was not ''special" , just cos it's a bit longer ? interesting though cos it's strange that it has single terminal
