Life is draining....

[Vulgar LS2]

From the battery on my 4.6 P38 (99 thor).

I replaced the battery to a bigger better one thinking that was the problem, but no it appears to be having the life sapped from it by something.

Anyone have any ideas, I've read eliots bit on the red light next to the gear selector and that is going out after 2 minutes or so as it should.

Is it time for a rag in the filler neck and a match?

For me it was the light under the bonnet. Once that was disconnected I didn't have a problem with battery drain

No light under the bonnet on my car.

check to see if your ign barrel is completely releasing when you withdrw your key....if it stays in the Becm will not shut down as it thinks the key is still in the ign lock..

I think it's releasing ok because the steering lock comes on as soon as I remove the key and the little red light next to the gear selector goes out after a couple of minutes, I believe that is the bcm shutting down.

Seen this?

Sounds like you have a parasitic battery drain. If the above isn't the cause you'll need to connect the multimeter as shown & start pulling fuses to find which circuit is the problem.

Interesting read, however I have a new problem now that it won't start, she tries to turn over but just can't.

The alarm has also gone off a couple of times and the dash display says " alarm triggered front rh door".

I think this is a problem with the remote locking, something is waking the car/computer up and draining the battery. Very common on the P38a.

I had the same problem with 1 I had. From memory remove the back right hand side panel in the boot and remove the connector to aerial in the side back window. The remote locking will only work when you are stood very close but It will solve the problem.

Remember reading a while ago similar and that one turned out to be

something to do with a bluetooth connection not being switched off ??

Silly question, I assume you have fully re-charged the battery with a battery charger?
Was the battery new, is it possible the battery is defective?
Earths all in good order? Battery connections clean & tight?

[Vulgar LS2]

Ok, just been to put it back on charge, whilst there I watched the red light again, after 2 mins it went out, then I pressed my garage remote control and it came back on. So I presume a door bell, alarm, other car fobs are keeping it awake a lot of the time.

So I've got access into the rear RH side panel in the boot and removed the blue wire that goes to the window, this has made no differance.
If I remove the little multi plug next to it this solves the redlight comming back on, but it also keeps the car imobalised and the fob will not work even from inside the boot. My fob also has a new battery and a strong range.


So my question is where do I go from here.

[P100]

OK, rhs side rear, remove the top panel and there is a small black box which is the receiver for the remote cdl. this needs replacing as it now looking at signals in the wider band than was intended. This is what is draining your battery.

A simple replacement is all that is needed, but...they are costly (£175).

Thanks Roy.


Righty hoo, she still won't start so Im going to pull the fuel line off to see if it's pumping. I've also put some petrol in it as it was low just to exclude that as a possible cause.

[P100]

be careful..trying to start it it may have scrambled the ECU code....you will have no way to know this it will have to be put on a machine that can programme this.

Where are you in the country ? do you have a good indy near you ?

Roy

[Vulgar LS2]

Hi Roy,

Im in Nottingham, no idea about a LR indy as I normally sort it myself.

What would have scrambled the ecu.

[P100]

The receiver does it when it see`s a signal to the ecu but not the correct one.. the Ecu has to send a signal to te Becm..if it does not match the car will not start until it gets the correct one !

I am in Tamworth but the car will have to come into my workshop for it to be fixed

[Vulgar LS2]

Would that allow it to turn over as mine is or just be totally dead on the ignition?

Can you send a link to your co or phone number.
You can pm through my profile.

I don't think that would stop it firing up though. This is a seperate issue to the power drain. The fking thing just won't burst into life and it's given no faults in the lead up to this either apart from not holding charge for more than 2-3days when left on the drive, and I've done nothing different, all i normally do if connect it up to the ctek for a few hours and it's right as rain.

It just gets better, it's snowing and I'll need it for pulling vans up the slope from my yard on monday .

bloody typical british engineering, great until you need it
