Flat battery - current drain?
Discussion
For the electrically-minded out there:
My battery seems to be going flat after only a few days. The car runs fine when jumped, and the battery is fine for starting after a brisk run, but a few days later is low again. It's only a year old and so should be fine, and the car gets a good run most weekends. I suspect there is a current drain somewhere (probably due to me messing around trying to get the cigarette lighter working again). Is there an easy way to test for this?
Cheers!
BTW no I couldn't get ther cigarette lighter to work!

Once the battery goes flat they're never the same no matter how old they are. So it may be worth replacing anyway. Regarding the drain - I've heard the alarm/immobiliser can cause this. Where do you live? Give Carl Baker of Car and Bike Installations a call (http://www.tvruk.tv/) - he is pretty much the authority on this stuff from what I hear...
Right were the battery is there are 2 relays. sould be a silver one and a black one.
i had a drain on the middle pin of the black 5 pin relay. i dissconected the one pin which had 2 white and orange wires going to it. turns out this was draining my battery over night!
every thing still works fine, im not sure what it does but it stopped the drain!
hope this helps

Not sure if this is easy, however connect a meter between the live cable and the +ve pole of the battery i.e. disconnect the wire and run it through the meter. Set the meter to amps (upto 1 amp should be Ok unless you have a massive drain) and you will see what current is being drawn.Now disconnect each fuse 1 by 1 and see if the current goes. If it does you've found the culprit. If not then it could be alarm or radio (my radio had a drain due to being permanently live rather than ignition live)
