Hi all. the battery warning lamp came on and stayed on yesterday (2007 RRS TVD8). Started ok this morning. Checked the battery after work today, 12.7 Volts with engine off, the Voltage rose to 13.7 Volts with the engine running and remained constant at 13.7 at different revs.
Is 13.7 Volts ok or is this a sign of the alternator on its way out? If it's ok any ideas why the battery light is staying on?
I should have tested it with lights and heated seats etc on to see what effect more loading has (I'll do that tomorrow).
Any ideas or advice would be much appreciated.
I did read the threads but couldn't find my exact problem listed.
Cheers,
Tony.

Further to the above post, battery lamp is still on. Tested battery voltage today, the voltage virtually remained constant at 13.5 Volts with engine running, despite the main beam, heated seats and radio all on!
All appears to be ok, so why is the battery warning lamp on?
Any advice would be greatly appreciated.
Thanks,
Tony.

Sounds like faulty diodes on the alternator, this could spell the beginning of the end for the alternator.

This happened to me earlier this year, exactly as you have said, then on the way to LR I got a bacon like smell and the voltage dropped . Luckily I made it to the dealership. Diagnosis was alternator foo@ed.

Good luck. 2007 RRS TDV8 Stornaway Grey with lots of smiles..

Thanks for that gents, how long was the light on for Sizzle before it gave up? I'm booked in a LR specialist on Monday to get a new throttle pedal (engine system fault - brake & throttle pedal incompatable positions).
Cheers,
Tony.

Just had the same come on in my car. Battery light has been on for 2 days now, does it go suddenly?

Hi Smoftah, mine kept charging for maybe a couple of hundred miles tops. Then I noticed the CD volume wouldn't increase and I was getting a message - something like "low power mode".
The alternator cost around £260 + VAT, the LR specialist forecast 6-8 hours work to replace (the radiator needs to come off amongst other things!).
I'm picking it up today so haven't paid the bill yet.
Good luck.
Cheers,
Tony.

I had my alternator changed last year at the main dealer I was recovered in to .

The Land Rover SRO time is 2.20hrs on a Range Rover Sport TdV8. There is also an SRO to test the Alternator which is 0.20hrs. So should be nowhere near 6 hours!

Cheers,

Thanks for that Tony

Best it get done sooner rather than later. Was the total bill scary?

£711 Total. One problem just seems to lead to another though. The alternator is now ok, but because they removed the negative lead off the battery, the aftermarket in dash TV has now stopped working!

Hi,

Sorry i just found the web site, My Bty warning light has been coming on and going off, finally booked it into get checked and yep the Alternator has gone. Symptoms i got bar the Bty warning light were Radio would not go above low power and rev counter kept fluctuating.

Hope this helps some one

Just to let you know, when my alternator was replaced, the "Landrover specialist" I took the car to, charged £711 to supply and fit a replacement (warranty partially covered that). The reason for this extortionate amount was that the front of the car needed removing to complete the job - bumper, radiator etc. I've since found a much more knowledgeable local landrover specialist who assures me the alternator can be accessed from inside the engine bay by removing a few pipes/boxes. He would have charged only £100 labour + the alternator!

Thanks, Mines in an approved warranty centre that have never changed one before so i am dreading the faults and aftermath mess they may cause

I've just pulled off the alternator on a 2008 td v8 3.6 today. If someone rekons they can pull the alt via the engine bay they are dreaming. took me ~ 3.5 hrs on the flat, a hoist would've been 2.5

Dunno how they get them out Martin all sorts of different ways people say
