HI EVERYONE, I'VE GOT A 92 3.1 AND HAD IT FOR GETTING ON 6 YEARS NOW, BUT HAVE RECENTLY HAD A PROBLEM WITH ALL THE WARNING LIGHTS COMING ON WHEN WE ARE DRIVING, AND ALSO AS SOON AS THE LIGHTS COME ON THE HEATER STOPS WORKING, WHEN THIS HAPPENS YOU CAN HEAR A CLICK BEHIND THE INSTUMENT PANEL SO I GUEST IT MIGHT BE A RELAY FAULTY. THE LIGHTS MIGHT STAY ON FOR 10 SECS OR THEY COULD STAY ON FOR 15 MINS, HAS ANYBODY HAD THE SAME PROBLEMS.
P.S I'VE CHECKED ALL THE EARTH LEADS AND THE WIRING AND IT IS FINE. (THIS IS A UK CAR).

There is a previous thread on this somewhere, quite recent. Something to do with the big blue relay in the fuse box?

It would also possibly mean the alt is not charging.

CHEERS FOR THE REPLY HARD 1 BUT THE ALTERNATOR IS CHUCKING ABOUT 13 VOLTS IN SO I DOUT THIS IS THE PROBLEM.
AND ALSO WE HAVE PULLED THE BLUE RELAY OUT BUT THIS DID NOT SHOW THE FAULT.

Just a friendly tip - on any forums CAPITALS are considered shouting. Posts are much nicer on lower case!

Sorry to be nitpicking!

[garry]

sorry paul not use to doing this many thanks, i only shout when the stupid lights come on.

Hi there

Mine was the recent query on dahboard lights, but that was on a newly imported 94 Bigfoot 3.1td. The advice was that there had been many newly imported vehicles with alternator/relay problems.

In our case the lights came on and stayed on. The blue relay was changed, and that seemed to do the trick, but not for long, so that meant a new alternator. The old one was still charging (so healthy voltage may not mean alternator is OK) but the controlling diodes etc were diagnosed as faulty. As I was planning to have a full service/check over/cam belt change I had the alternator changed at the same time. I should get the parts under a 1 month guarantee, but as the seller is 450 miles away that is still under negotiation!

We only got the vehicle back tonight but it seems perfect, and the only quwstion mark on the vehicle is some corrosion on the inside of the rear discs, which we will keep an eye on. Otherwise very pleased with an otherwise nearly pristine vehicle bought at 64,000 miles (103+K - don't have the calculator to hand!).

I would have liked another Disco (old one getting long in the tooth) but they are very expensive, and still have children to feed. Enjoying the Isuzu very much and, as my wife says, nice to have a change.

Incidently just driven 300 miles in a nearly new Nissan on hire (on business as I had to go into a remote area off road) - what an awful vehicle, poor ride, agricultural engine and very noisey. Eleven year old Trooper much better! (Sorry if anyone has one!).

yep change the blue relay they are prone to going wrong

[garry]

cheers markboy, i will get one on order on monday and i will let you know weather this solves the problem.

@ garry

I've just had a similar thing start on my 93 3.1TD - did changing the blue relay sort out the problem?

[garry]

hi rock69, since posting my problem i have changed the relay but it has not solved the problem, i must admit it does not happen as often but the problem is still there, this is doing my head in at the moment with all this snow because the heater goes of as soon as the lights come on so the windows steam up straight away( don't get the wrong idea ) just bad weather, if you find any more leads to the problem please let me know. many thanks for your intrest. garry

[Rock69]

I'm gonna take a look at it in details tomorrow, but because the problem is so intermittent i dont really know were to start.

A head in the manual is probably the first step

I'll keep you informed.
