Good 'ol leckkie again

Well after 3 problem free years I had a bit of a shock!

'96 P38 2.5 DSE

Used to get the flat battery problems, a couple of days non-use & she was dead.

Did the usual, upgraded the RF reciever, checked for BECM going to sleep etc.

Ended up fitting a 1000 ah cold-crank battery & no more probs until now!!

She was running before I let go of the key

Went out, remote wouldn't unlock, eh? Key in, unlock, but only driver-door,

key in ign. ZILCH!! No lights on dash at all, not even a glimmer.

BORROCKS, Had a rummage & pulled out the booster-pack,

WHAM, it fired straight up, ran perfect, no re-sync, no messages, just a dead radio, which I re-coded, had a look at the charge-window on the battery & it was black, should be green, ran it around for a few miles, right as rain again.
Question 1 : it was totally dead, even the radio lost its code, so why no re-sync of the key (i'm glad about that 'cos it was a bugger to do last time)

Question 2: WTF caused it? as its ok again (at the moment)

I wonder if there's a relay somewhere that 'stuck' open & allowed the battery drain.

Woja fink?

Fuse box, alternator or as you suggest a stuck relay. If the battery discharged very quickly, I'd suspect the alternator.

Is the battery three years old then?

Good point, if the battery is 3 years old could be a duff cell.

Datatek I always check mine every 3 months, water levels that is let it get low and kaput. Owning a battery fork lift helps you realise when they cost £1500 a set

Ah my batteries are sealed, no need to check.

I used to have a Crown battery fork lift, used to check it every Monday morning. Used to suffer all sorts of electrical bad connections, bit like a P38 really

I had a problem like this, and yes it turned out to be the battery. Would report the battery was ok then without warning would be totally flat...

headlight wiper not properly parked?

mine does it all the time when it has dry head lights,you can reajust them it's easy one 10mm bolt
