Getting pretty ****ed off now...

As the title says, I'm getting ****ed off with my alternator/battery/what ever is in between. It's a 200tdi

The battery kept dying so I changed it for a new one, this battery had died a few weeks ago due to leaving the lights on, so I thought that the cold was affecting it in its fragile state.

So new battery on, car starts, happy days. Next morning car doesn't start again!!

Start it with someone else's battery fine and put my battery back on hoping the alternator would charge it back up on the way to work (15 miles away).

Got to work and turned the engine off, then tried to start it straight away and it just clicked!

Had a look at the terminals and saw that the cable from the alternator had come away from the battery terminal so I replaced the connection and refitted, drove home and still no charge.

So I have replaced the alternator with a brand new one. But guess what.... Still no charge!

The multi meter is reading 14.05 volts with the engine running of the battery and off the back of the alternator (with out lights, radio ect on)

The battery is reading 12.66 volts with the engine off.

The battery warning light is extinguishing when the ignition is started, but what I have noticed is it comes on when I turn the engine off.

Any ideas?? Tried everything in all the searches I have done

something some where on your landrover is draining he power from the battery as it looks like its charging perfectly fine try taking your fuses out one at a time to see if it stops it draining the battery

the batery warning light will come on when you switch engine off as its not chargeing with engine off

As Dirty Tom above and nothing else.

Have you checked your earth strap. Can cause naughty electrical thingies

how is alt wired ,battery feed to b+ ignition light d+

How do you manual trigger it?

Would that be causing the battery not to charge?

Can you concentrate on just one thread as there is alsorts of extra info on your other thread.

I put it in the disco thread, then realised that it would get a better verity of answers if it was in general chat instead

To drain a fully charged new battery overnight also seems a bit exessive to me. My advice would be to disconnect cables and leave it over night, re connect in morning and if it starts first time you have a short circuit somewhere. Classics for this are inside lights, places water can get in and corrode creating a path.

I maybe teaching you to suck eggs but here is how to use meter to check for circuit fault while pulling fuses.
If everything checks out OK and voltage same over night which it should be on a new battery, reconnect the positive battery cable. Now with the negative (ground) cable off, use your meter to determine if there is a drain on the battery. Do this by placing one probe on the battery grounding terminal, and the other probe on the battery grounding cable. There should be no voltage showing.

With this accomplished, check to see if there is voltage showing between the battery ground terminal and the ground cable. If there is, start unplugging fuses one at a time. After each fuse is unplugged, check to see if voltage is still showing. If you notice a voltage drop, make a note of which fuse was removed to create that drop. Continue removing fuses one at a time until no voltage is showing on your meter. Whichever fuse was removed that resulted in no voltage showing is the circuit causing the drain, bare in mind though that you will be pulling juice for interior clock/alarm so you looking for other circuits.


Also check your earth onto car body, disconnect and clean up if corroded and not look good.

I am not to sure if vehicle has many relays but again if so one may be stuck so a couple of 'magic taps' on them may free a sticking one, you will need a haynes manual to point you in right direction. 14V charge though is ample for the battery so no issues with alternator.

Charged overnight or not..a fecked battery will only deliver one shot of CCAs...you need a new battery.

It is a new battery, had 2 now
