Hi!

I have a major electrical problem in my Discovery I -98. All of the problems below occurs intermittent.

Problem 1. It all started when i pusched the two button remotcontrol to lock the car, then the alarm started to sound. I unlock the car with the remote without any problem.

Problem 2. After this problem the right indicator started to shine constantly when I moved the indicator stick to the right. And the green indicator symbol started to shine as well. I then cecked all the fuses and they were fine. But when I pulled out fuse nr 1 in the facia fusebox (indicators and brakelight) and then lock the car with the remote without any problem. The alarm and hazard blink three times as it should. When I put the fuse back the same problem occur.

Problem 3. When i pusch the hazardswitch all the warninglights (SRS, glow, oilpessure etc) start to blink together with the hazardlights.

Problem 4. The next problem that occurd was that the car wouldent start, like the battery run flat. But after trying to start a couple of times the cars start without any problem, but with a lot of hessitating from the starter. Its like a jeopardy for two days if it starts or not. Then all of a sudden its been working for a week without any problem.

Problem 5. When pushing the hazard buttom the front wipers starts and they sometimes move slow, sometimes fast. This fault have only occurd one time.

Problem 6. After a week without any starting problems but with electrical problem with the indicator and hazard + warninglights. The cars suddenly wont start again. I tried to start the car three times but startermotor wont start the car, almost like the battery is run flat (battery fully charged the night before)Its just a clicking sound. Then on my fourth attempt to start it starts like it never have done before. With full power!

I have now checked every fuse again, and checked all the earthing points in the RAVE manual. I have also tested the MFU by doing the MFU test with the heated rear window switch. The only thing that wouldent self test is the rearwiper washer fluid.

What can be the problem, feels that I have tried everything, please give me som thoughts, tips or new inputs! Family planning to drive to Spain in February. Please help!

 

You have a bad ground somewhere. Go through and clean an tighten all the grounds on the truck.

 

Thank you for your answer!

I have worked my way trough all the cars eartingpoints with the help of the electrical trouble shooting manual on my RAVE Cd. Have I missed some place or is there any common points of earth failure on Discos?
