HELP...Sudden loss of A/C, Radio,ECT... - Land Rovers Only

LANDY96 · 08-19-2006, 08:24 AM

I was driving with the A/C on all the way, and the radio on, and all the sudden I lost the following...
-A/C, and fan
-Radio
-Fog lights
-seat control
-dome light
-Clock
I checked the fuses, all are ok, I assume it is a ground issue.....

I don't know what else to do. I have checked the ground behind the battery, and by the master cylinder. What else can I do????

You may think this is crazy but all off those are accessories.
Have you checked your ignition switch?
When my switch failed I lost my window control radio, etc...
When I checked the back of my switch it was coming off. So I cleaned the contacts and zip tied it back together.

Okie has a good point, I think that would be the first place to look.

I am pretty sure this is not the problem, however I did open the ignition up on the back side. Where the copper striker, hits the ignition plug, it it looks ok. Think about this though, the hood lamp doesn't work, the drivers side seat controls don't work, clock..(this is supposed to work all the time) The alarm system has problems. It is like there is no electricity getting to these systems. Is there a relay, or a specific ground I can check? I am going insane here. I need to get my Rave CD back, so i can get a wiring diagram.... PLEASE MORE SUGGESTIONS!!! EVEN IF YOU THINK THEY ARE SILLY!!!!!!!!

Ok, a wild thought.....

I was reading a post about the tach giving problems as evidence the alternator has problems. Ok, well the PO put a new alternator on it, citing loss of power and other things. No mention of electronics cutting out from what I remember though. Well, my tach when I would start it, would jump up and down for a min, before settling into place. Ok, no biggie, well, I also changed my water pump last weekend, and I had to move my alternator around. I noticed that my alt, is pretty close to the valve cover, and it is touching it in some areas. Could my voltage regulator have problems, or could it be getting too hot, since it is touching the vlave cover? Or a grounding problem.

I doubt its the alternator. Do you have the same problem with the engine not running?
Take your multimeter and check the fuse box were this stuff comes from, is there power there? If you have power here then start looking for the reponsible ground connection.

I have power at the fuse box. If I did not the other periferals would not work....right...? I did get a meter, and check the fuse box. The fan and A/C did not have power though. So in my conclusion it has got to be a ground...but that is my question. Where do I look for the ground. I have access to the Rave CD, but it only goes to 1995. Not 1993? So would they be the same even though the interior had some changes?

I found this on another forum. What do you think... With the exception of the sunroof. It is identical to my problems. What do you think of the solution?

Disconnect the battery and use the ohm/continuity function on your meter to check for continuity of the battery cable to fuse box and also at one of the non functioning loads. Consider the ignition switch as you do this. Switch it on and of etc. Also you can measure from the load to ground to see if that side is connected or not. The 95 Rave should be close enought for grounding etc.

I have properly diagnosed and repaired many of these electrical issues on my land rovers over the years and those recurring phantom failures have just about dissapeared. Most were bad work at the factory. When I got my 88 in 92 it had many issues that were never correctly addressed by the dealer. Considering it was an expensive car thats pretty bad. It took a home mechanic (with some electrial experience I must admit) to solve what the dealers can't or for lots of money.

Don't give up and learn how to do this one by one. You wont be sorry and will start loving you landy even more,

Serious!

THANKS!!!!

This is good info! I have a question though, It is hard for me to decifer the Rave info. I am used to other manuals. Japanese cars to be exact. It was real easy to follow and diagnose. I don't understand, or I am looking in the wrong place for specific ground info! Rave tells me common ground, but not where they are located.....

I will check the continuity between cable and functions!!

8895rrc · 08-20-2006, 07:38 PM

Never mind the ohm meter.

This is from glancing at the Rave manual:

None of these are sharing a common ground point.

The clock stopped working? Really? There is a 10 amp fuse that protects the "always on" items like the clock and the memory to the radio. It should be in a little fuse box separate from the others but I don;t know where in oyur car. If this is blown there must be a reason for that. Try another fuse (no bigger then whats there right now). If this fuse is good and the clock does not work then check the fuses under the hood.

If this did not help then post again what you found as there is more...

Problem solved!!!

The fuse link at the Battery had a broken wire! Cleaned it, and re-soldered the connection. I was told that the whole thing should be replaced. But I didn't as of yet. I can't believe there is no mention to this anywhere.......

This apperently is a frequent problem, and there doesn't seem to be too much info around on this. I had to did deep into the LRX forum, and found someone with the exact same problem. Thanks so much everyone for your posts. I hope this information will help someone else!
