We recently had our battery go flat on our Rangie and as the battery was around 3 years old, we bought a new one after checking the obvious – alternator, battery terminals, nothing left on, etc.

Next day, our new battery was flat – What the !!!!

Now this was not going to be easy as I had heard of newish Landrover vehicles having flat battery problems and the cost of getting these problems fixed is horrendous.

I put another battery in from the Troopy and started to find out what the problem was. The alarm and keys/remotes had to be reset which upset the neighbours for a while after having to learn how to reset the key/remote as I would have set the alarm off at least 6 times and once it is going, you either disconnect the battery or let it time out. If anyone wants to know how to re-program the key/remote, let me know, it is easy as and an easy source of revenue for Landie dealers from what I hear.

Next I put an ammeter in series with the battery and found a current drain which ranged from 2.5A to 560mA – enough to cause some grief. All 80+ fuses were pulled and only when 2 of the bigger ones were pulled did I get a current drop to around 20mA.

After a lot of research, I found that these fuses were for the computer that basically runs the vehicle other than the engine or transmission. Even opening a door tells the computer to turn an interior light on.

Still no real progress so onto the net and phone which gave be a couple of clues. I then decided to go bush offroading, then in the bush re-attached the ammeter and after 5mins of seeming 2.5A and 560mA, the current dropped to 20mA. Why is it OK in the bush and not at home???

Home again and I started turning off wireless devices in the house (no wireless stuff in the bush we hope which is why I went there to do a test) The theory was that as the remote for the vehicle is wireless, the remote receiver in the vehicle as picking up a wireless signal from somewhere and turning the computer on waiting for a code from the remote that never arrived so the computer just stayed on waiting for the code and flattening the battery.

After turning off the wireless mouse, WiFi internet, 2 x cordless phone systems, etc until I got to the wireless energy monitor that is in our power board – turned that off, hey presto, 20mA – problem solved now that we have taken that device out.

3 days of scratching the head and having SWMBO saying take it to the dealer and we found it. The dealer would never have found it.

I have heard since then of a Ferrari and Subaru owner that have a similar problem and think that I may be onto something as their dealers are stumped and both are garaged in high Radio Frequency (RF) environments and only have the problem when they are in the one garage, never anywhere else.

These vehicles are obviously "not fit for purpose", if they can't cope with the real world of electronic devices everywhere.

Mike,

I am curious, how many times have you had success running the "fit for purpose" argument against a supplier?

My mate has a TD5 Disco. Would not start. Phoned Landrover Assist.
LRA: "Sir, where are you?"
Mate: "In a shopping centre."
LRA: " Is there an Amcal chemist nearby ?"
Mate: "Yes there is"
LRA: "Would you please ask them to turn off there scanner for a minute"

They did and it started !!

It's absolutely frightening to even think of some of the reasons for the cause that a dealer would have come up with and the number of items that would have been replaced be themn let alone the final cost. Well done.

A question for Stevesub...

Over what distance was the energy monitor able to affect the vehicle? - and is the energy monitor the device marketed as "Cent-a-meter"?

Thanks

There was me thinking that "Lucas" The Prince Of Darkness was back at Solihull again.

Glad to hear you found it, and that all is OK.

Computers are a fuuny thing hey. There is a spot in Townsville where if you get stuck in traffic, at low speed, BMW's just shut down. If you are rolling alog at 70ks, all is ok. They seem to get through the "dead spot". RACQ go out, push it 100mtrs down the road and off they go again. Last I heard, everyone was still scratching their heads as to the cause.

Landrover Electrical problems yeah right. Ive had 2 a SE7 1997 and TD5 2001. Have had 3 window mechanisms snap on me, rear door seize up due to dust, and the ABS Modulators in the TD5 are prone to not work. Replacement is $3500 but got one on Ebay for $1000 from Nth USA. Yes Landrovers ride nice, look good and okay around the CBD but not nice off road with dust blowing into the vehicle. My wife kept at me about Toyota. We test drove a Prado, and it just drives like a car. And the Disco visability is lousy, not to mention the astonishing resale value of Landrovers. Toyota you rock!!

You appear to have missed your true calling as either an actuary or an electrical engineer, or perhaps you are.

So gee whizz, with the direction the auto industry is going with pure electric cars and very complex cpu's and no-crash programmes etc toward almost no driver stuff, how do we think this will mesh with omnipotent wireless networks at mega speeds, wireless hi fi systems all around and outside our houses, more powerful mobile phones ... I can just imagine someone getting home and the phone ringing and the oven saying dinner is ready to your mobile and the TV kicking on because you are home but because of all this the car is turned on and sensing a wall in front of it to avoid the crash reverses at alarming speed driverless down the driveway ...

I am hoping, perhaps against hope, that electric vehicles will be far simpler than what we have now ! Just a battery or two or three, and one or more motors - no need for complex CPU's, just a simple controller - simple enough to carry a spare.

uh.... don't get me started on those fine pieces of hardware! Against my best advice, a mate of mine went and bought a wireless kit for surveillance around the place. We put one in to see how it goes, having the slight suspicion that it will take the WiFi network down - you know the 2.4GHz was a bit of a dead giveaway. Lo and behold - it did. 2 macs, 1 pc and one cisco wifi router had to be solidly bounced [cold booted] as the result of merely powering on the camera.

The damned thing I could only suppose it would spray manure across most of the 2.4 GHz spectrum.

He then listened and grabbed a wired camera. Much more of a better choice.

Something I just learnt today about cars etc with computers, alarms, coded radios etc.. I purchased a Ctek 7000 battery charger for an AGM aux battery for the Cruiser - tricky little charger that has a 4 stage charging process and supposed to be real good for that type of battery.

Now get this for those who are changing batteries and having a fight with the alarm/engine immobiliser etc - in "Supply" mode this unit will also power the system while the battery is being changed [up to 7 amps, so I would not be turning the ignition on while doing it).

Sold me, mate. Dropped the credit card on the counter straight way.
