 hi there ive got a 2001 omega fitted with a 2.2td engine and im having a bit of a problem with stopping the battery going flat after being parked for more than one day does any one no if this is a common problem or help in any way ,many thanks rich

[Dave DND]

Get the battery itself checked - they don`t last forever

Most tyre centres or battery suppliers will often check this for free for you

tryed that one had three on it now in 12 months and they have all been tested and said to be ok all seem to be charging aswell is as if the electric fairy steal it all .

[Dave DND]

In that case, its out with a clamp meter to measure the battery drain at rest and to see where the volts are dissapearing to.

Worth also unplugging the alarm powersounder for a few days as this can often be a very good place to start

As Dave says .. first port of call the powersounder .. then its the longwinded way !!! pulling fuses to see what is doing the draining ... My initial thoughts to try are the boot light circuit and the cigarette lighter circuits ... could take a while to track it down ..

 my last car was a vectra 2.0td done the same thing it turned out to be the ignition thingy at the back of the barrel was the problem woren contacts.

If you can find someone else not using there car, then swap the battery, and see if that one drains as well. Will save u buying a new one, just to find that drains anyway

cover the battery and keep it warm you are in the coldest place.

thanks for the help guys the trouble is the has been to the auto electrian 3 times and comes back every time saying its ok and then go's flat again just wondered if things like the alternator can loose charge when parked up other than that might be time to get rid of the dam thing .

Suggest to try a different autoelectrician that knows what he`s doing.

Also, update your profile with a location, as someone nearby may be able to assist further

[Dave DND]

Have you tried the previous suggestion of unplugging the power sounder ?

 :-?

What current draw are you getting 5 mins after ign turned off?

 :-?

[SteveMJ]

Connect an ammeter in series with the battery and measure the 'off' current.

You could buy a cheap multimeter (Maplin as a guess for under a tenner) with milliamps range.

The 'off' drain should be only in the order of 10 to 100 of milliamps - I doubt a clamp meter will be adequate to do that.

One area to check is the boot light - as prblem (IIRC) on Senators

had the same problem and sent the battery back to the supplier - turned out it had a faulty cell that kept breaking down under load but checked out ok on a meter - put a new battery on and now no more problems
