battery died again !!
« on: 19 May 2007, 16:53:05 »
a few months ago i went to start the car and found out that the battery was dead. as i had recently boought the car, and not knowing how old the battery was, i decided to buy a new one, ive had no problems since then- approx feb.
i went to start the car this morning, after its had a week off and it was dead. i booster packed it and it kicked into life! later it was all ok again. i have checked all the interior lights and contacts but they are all ok- so i have a drain from somewhere, anyone got any prime suspects on this one?? cheers tone.

Boot light is a favourite.

You need to check the current draw using an ammeter to prevent a wild goose chase. If there is some with the ignition off, start pulling fuses one by one until is goes away. Then you know the circuit with the problem.

cheers, i checked the boot light -but a light touch on the door sw turned it off, and just in case i have a peak through the back seat. but i will get the tester out and start the fuse pull option, i was hoping it may be an easy jump to fault,never mind eh!  tone.

Good diagnostic advice here... if you want to save resetting codes etc then connect your ammeter into the circuit before you remove the battery lead so that you dont interrupt the voltage.  (Dont switch on anything too juicy or you'll blow the ammeter/fuse though, yeah I know sounds obvious but had to add it for completeness!)

See if you can get one that will display 10A - some of the cheaper ones only manage very small currents...

Ideal  :)  You probably will get a small current draw with everything off, but it ought to be real small.  Like a fraction of an amp.  Any more than this and it will drain the battery over time...

I've seen knackered cdl motors cause this, along with hrw relays etc.  Could be a number of things, and be intermittent.

That would take a good 1.5 - 2 days I reckon to flatten it....

If the bulb is 5W (rough guess) it would take 168 hours (exactly 7 days) to completely flatten a fully charged brand new 70Ah battery.

Of course the battery won't be perfect, the discharge will slow down as the battery voltage collapses, the car needs say 20 Ah in the battery to turn over, etc. But it gives you an idea.
