    Battery light in Tdi Defender - Help !

    OK so the last few times I've driven the Deefer, the red battery light has been constantly illuminated. I thought it might have been due to the rain or something but it seems to be permanently on when the car is !

    What's the likely culprit? Dead battery? Dead alternator ? Something else?

    Please le me know what checks I can do to track this down. Oh and if you tell me to use a multimeter please be VERY specific eg what to set the MM to etc.

    Thank You

    Yes will be the alternator dying/dead or just a loose connection on the back. Check it b4 you plunge on a newie. The originals can be rebrushed and rebearinged, they are just a nippondenso anyway. About 2-350 for a new 1.

    Dang it! got keen on hitting the post button! Any way check the voltage output on the alternator, connect the MM to the battery is easisest, put it on the seat beside you and note V, start the engine and take note if the Vs rise. If not its sus.

    Mine was a snapped bolt holding the serpentine belt tensioner on still trying to get the bloody thing out. Then I discovered that I didn't have power steering either or water pump for that matter.

    Have you had a look under the bonnet to check the wires are still attached to the alternator?

    If you can take the car to an auto electrician and ask them to check the battery etc they should check to confirm that its being charged as part of the process. This should narrow the fault.

    pretty sure Ive got a couple of working TDI ones hanging around if you need a loaner,

    check your battery voltage with the engine running if its over 12.8V the alterntors doing something switch on all the electrics and if it doesnt dip then you can keep drivign for a while till you can get it fault found.

    As said alternator

    By the fact you can drive it and worrying about the light being on tells me it not the battery.

    If it is your alternator........I upgrade to the 100amp disco unit

    The only thing you have to do is decided whether you run a disco or defender sure time belt.....I didn't bother swapping the pulleys over so I now run a disco belt

    Drop around if you like.....at this stage I'm home all day
